However, if you instead open the Adjust Last Operation panel, it will list a different operator name (Loop Cut, not Loop Cut and Slide), and while you can change properties there, those changes have no effect, even though they are reflected by the operator panel.\nThis didn't use to happen in 2.79b, though IIUC the \"Adjust...\" panel is different in 2.8x from the \"Redo Last\" of the 2.7x era.\n\n1.

It also may be nice to allow setting overrides at several different levels of abstraction.\n\nThus:\n\n* Allow an optional default value that would be returned by the variable if the referenced property doesn't exist, instead of failing with an error.\n\n* Allow fallback from Layer to Scene, and then World: one World can be used by multiple Scenes, which can have multiple Layers.\n\nSince this all only makes sense for *custom* properties, maybe it can be a new mode specifically aimed at them, e.g. some kind of \"Layer/Scene/World Custom Property\", which has options for the custom property name (without the `[\"...\"]` quoting), channel index (for vectors), and default value.\n\nThese are things missing for the new driver things to fully cover the features of the View Layer mode of the Attribute material node.", "popup window call operator will crash blender\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.96\n\nBroken: version: 3.2.0 Beta\n\nThis script is use to check the active material, it can be run correct in the main window, but not popup window(change the pref window to node editor)\n```\nimport bpy\n\nbpy.ops.screen.userpref_show(\"INVOKE_AREA\")\narea = bpy.context.window_manager.windows[-1].screen.areas[0]\n\n\narea.type = 'NODE_EDITOR'\nflip_header = True\narea.ui_type = 'ShaderNodeTree'\narea.spaces[0].node_tree = bpy.data.materials['Material'].node_tree\n\nfor region in area.regions:\n if region.type == 'HEADER':\n with bpy.context.temp_override(area=area, region=region):\n if flip_header: bpy.ops.screen.region_flip('INVOKE_DEFAULT') # this line will not\n\n if region.type == 'WINDOW':\n with bpy.context.temp_override(area=area, region=region):\n bpy.ops.node.view_all(\"INVOKE_AREA\") # this line will report context error\n```\n\n- Open .blend file\n- Execute script\n[#98491.blend](T98491.blend)\n\n\n\n", "Polishing the Painting Experience\nThere are a few tasks that would enhance the texture painting pipeline that could be prioritized before advanced features like layered textures is even considered.\n\n## Existing Painting System\n\n### Small Tasks (e.g., bug fixing)\n- [ ] Graphics Tablet Lag when in Texture Paint mode in Blender 3.0 #93796\n- [ ] Undo bugs\n -

For instance really dense drawings with small lines with little to no curvature still tends to flicker a lot.\nAnother case is when the gpencil strokes intersects the scene geometry. This makes the line less thick to the post process which makes it too small.\n\n## Proposed solution:\nWe propose to implement a Temporal AntiAliasing solution. It is robust and will match Cycles & EEVEE's film filtering if using the same filtering function. This only adds one temporary buffer (low VRAM usage compared to rendering at higher resolution) and is completely self contained (works with transparency and don't interfere with other features).\n\nI propose to only implement this for final rendering since it might introduce flickering that might be annoying while drawing.\n\nHowever this wouldn't solve the issue of gpencil strokes intersecting geometry.\nFor this I propose to erode or reproject the render's depth to match the render sample of the new AA scheme. This should fix the second problem completely.\n\n## Technical details:\n- Implementation just need to be ported from Workbench which has a lighter form of TAA than EEVEE. Also [D10414](D10414) can be of great help to reduce render/convergence time.\n- Depth buffer modification can be implemented after new AA is in." ]

Previously I could create a proxy for each controller and use those to animate the linked asset whilst retaining the full functionality of the rig. Now that create proxy has been removed, I can't just override a single controller. Instead I'm forced to unnecessarily create overrides for several thousand objects!

In the `World Shader`add a `Magic Texture` node and connect one of the outputs to the `Volume` socket on the `World Output` node.\n5. You will noticed that in the viewport you can see the `Magic Texture` is projecting light onto objects in the scene, but you can't see the `Magic Texture` directly.\n6. Place a `Color Ramp` node between the `Magic Texture` and the `World Output` nodes. Now you can see the `Magic Texture` in the viewport.\n\nAnother test:\n1. Create a scene in Cycles.\n2. Change to the rendered viewport.\n3. Open a shader editor and change to the `World` shader and delete the `Background` node.\n4. Add a `Noise Texture` node and connect an output to the `Volume` socket on the `World Output` node.\n5. Notice that you can see the impact the `Noise Texture` is having on the scene, but you can't see the `Noise Texture`\n6. Place a `Color Ramp` between the `Noise Texture` and the `World Output` nodes. You still can't see the `Nosie Texture` in the scene.\n7. Place a `Volume Scatter` node in the `World Shader`, connecting the output to the `Volume` socket on the `World Output` node and connect the output of the `Color Ramp` node to the `Density` input of the `Volume Scatter` node. You can now see the noise texture in the volume if you have a light in your scene.\n8. Select the left most handle (the handle that is black) in the `Color Ramp` node and drag it closer to the position `0.5`. You will see the results you expect until you reach the position `0.5` where the volume will seem to disappear from your scene. Yet when you look at objects in the scene, the light reaching them is still affected by a volume shader you can't see.\n\nHere's a video demonstrating this:\n[Volumetrics not visibile in viewport in certain sitautions.mp4](Volumetrics_not_visibile_in_viewport_in_certain_sitautions.mp4)", "Apply scale normal flipping\nThe apply transforms operator in blender can apply negative scaling to an object.\nHowever there is two ways to do this. If you scale your model with a negative\nvalue in editmode, you get flipped normals. This is because the vertex order in the\nfaces is preserved and that is what determines the normal. In object mode however,\nthere is a flag in the render engines to flip the normals back, if they are flipped due\nto negative scale. This inconsistency creates the problem with the apply transforms\noperator. The following image shows on top the behavior in editmode and at the\nbottom the behavior in object mode.\n\n\n\nOf course both behaviors have their reasoning to exist.\n\nOne reason for the rendering flag to exist is, that instances of the same object can\nbe mirrored without causing normal problems. Obviously there is no other solution\nto that, since the underlying mesh is the same for all instances, so the render engine\nhas to handle negative scales.\n\nOn the other hand, in editmode you don't want to change the loop order for all your faces\nif you are just scaling. It makes much more sense for editmode scaling to just change\nvertex coordinates. That means you need to fix the normals manually.\n\n\nThe apply operator can only be called in object mode. From object mode the current\nbehaviour looks as if it was flipping the normals. Actually it is just applying the\ntransform \"in editmode\", which looses the negative scale information for rendering.\nThis looks like a bug to some users and is confusing for new users. Users have actually\nrequested this to be changed:\n\n4Zdbbc/\n\nI also heard this request on the BCON22.\n\nHowever the question arises, do we add another option or do we just always flip the\nnormals to make it consistent with rendering? Another question is what happens to\naddons which are using this operator if the operator gets changed in this way?\nHow many addons are actually using apply scale on negatively scaled objects?\nDo those addons fix the normals by flipping them manually?\n\nThere is already a patch available to add this normal flipping without an option:\n\nD16382", "View zoom (scale mode in particular) doesn't work well when dragging horizontally, or crossing the middle of the screen\nBroken: 2.79, 2.80, 2.81 HEAD (8c9e6f123a2).\nWorked: ?\n\nNavigation Mode Scale Is Broken - it should never be calculated from the vector zero.\n\n- Set Blender Navigation to Scale\n- Try to press Alt + click and drag in viewport to make it zooming (or click and hold the \"zoom\" icon in the viewport).\n- Try to cross the mouse arrow in the vector zero (i.e., cross the mouse around the middle of the viewport).\n- As you can see the tool start to work weirdly inverting the zooming as soon you cross the scene vector zero.\n\nNote: The other zoom modes (e.g., dolly) also present a strange behaviour when zooming horizontally.

that there is an access violation when reading at position `0xFFFFFFFFFFFFFFFF`. `node->typeinfo` does exist (is not null), but `freefunc` (and actually most of the other attributes) point to `0xdddd...`. Because of that, I think that this bug might be caused by a similar issue as described in #72833.\n\nI'm not sure if a core dump helps you, it's quite large (1GB + another GB for the .pdb file) so if you need it I can look for a way to make it available to you. I'm not a C or C++ dev so I don't know what is helpful.\n\n**EDIT**: I think this crash is caused by opening files files with nodes that were registered while the file was originaly saved but not anymore.\n\nIt's a bit complicated because it doesn't happen all the time. The particular file(s) where I observed this issue use nodes from an addon (Armory3D) which supports per-project custom nodes which get registered via a `on_load_post()` handler (so there is a delay between opening the file and registering the nodes). I'm not entirely sure, but it seems like the crash occurs when the nodes are registered again. The crash even occurs when unregistering the nodes before saving the file.\n\nBecause of that complicated setup (addon required + project setup + custom node package) I will go without an example file. If you aren't able to find the cause without one, please tell me so that I can prepare a minimal project setup for you.\n\nThank you very much!\n\n*Original issue*: 1890", "Crash (memory use after free) on freeing RigidBody world\nReproducible with current master, probably there since forever.\n\n# Steps\nWith an ASAN build:\n\n- Open `rigid.anim.blend`\n- Close Blender\n\n[rigid.anim.blend](rigid.anim.blend) \n\n(Case found while working on #86379 (When using \"Append\" rigid body objects + empty constraint, none of its constraints work.))\n", "Crash when run the script code follow\nOperating system: Mac 11.4\nGraphics card: Intel Iris 1536 MB\n\nBroken: 3.0.1(2022-01-26)\n\nBlender crashed when running the script followed in \"Scripting Window\":\n\n```\nimport bpy\n\nfor obj in bpy.data.collections['Bg_objects'].all_objects:\n obj.is_holdout = True\n```\n\nAddressSanitizer error log:\n```lines=20\n==34714==ERROR: AddressSanitizer: heap-use-after-free on address 0x00015d792c38 at pc 0x00010523645c bp 0x00016fdfa1d0 sp 0x00016fdfa1c8\nREAD of size 8 at 0x00015d792c38 thread T0\n -

While the file is being written, Blender's UI is gray and unresponsive.\n\nThe problem is not pressing, as usually it takes considerably longer to load the files in the first place. I've asked some artists at the Blender Studio and they didn't really consider the delay when quitting Blender a practical issue. Still, it gets somewhat in the way of quickly testing things with various production blend files, so it could be seen as an issue for developers more than for artists.\n\n### Possible Solutions & Impact\n\n**Simplest solution:**\n\nAs a solution we could introduce a user preference \"Save Recovery File\" that is enabled by default. Disabling this option would:\n- Avoid writing `quit.blend`.\n- Remove the \"File ‣ Recover ‣ Last Session\" menu item.\n- Remove the \"Recover Last Session\" button from the splash screen.\n\n**Alternative solution:**\n\nThe \"Recover Last Session\" operator does not poll the filesystem from its poll function. This means that the operator is available even when the file `${TEMPDIR}/quit.blend` does not exist. Changing this, such that the operator is disabled when `quit.blend` does not exists, means that the above solution would not have to remove the recovery operators when \"Save Recovery File\" is disabled. The operators would auto-detect whether a recovery file is available at all.\n\nThe upside of this solution is that it makes the \"Recover Last Session\" operator appear more reliable, as it refuses to work when it knows it cannot do its job. This would be an improvement regardless of the \"Save Recovery File\" status.\n\nThe downside is that an old `quit.blend` might be lingering around after \"Save Recovery File\" has been disabled.

This could be avoided by removing `quit.blend` when disabling \"Save Recovery File\", but I'm not a big fan of Blender explicitly removing files that are meant to recover from human error.\n\n### Discussion Topics\n\nThis task is meant to discuss the following:\n\n- Do we want to make it possible to quit without writing `quit.blend` at all?\n- If so, which of the solutions is preferred?

What is the best thing about them: the user doesn't need to worry about the animation if some point change its location.\n\nBut there is an aspect of easing equations that still can be improved. They don't follow the normal of the curve. In an animation, this mean that they can break any previous movement of a object, instead of starting from it.\n\nCurrently, this is what happen if we change the bezier control point of the start point of an easing equation Cubic In:\n{[F86114](blender-cubic.gif) size=full}\n\nFor Bounce In:\n{[F86115](blender-bounce.gif) size=full}\n\nYou can see how the animation break when the easing start, because the first internal point of the easing curve doesn't follow the previous curve normal.\n\n**The proposed solution**\nTo solve it, the first internal control point of an easing equation should be placed above the curve normal.

And these options are actually new, so I would not be worried about breaking backward compatibility for the previous easing curves that will change now with follow normal by default.\n\nThe most important thing about the easing equation is that they allow easy, smooth and automatic animations.

This could be controlled in the Properties like so:\n\n{[F8363009](Screenshot_2020-02-22_at_17.34.54.png), size=full}\n*(The search box is added here to reflect how the Properties will be updated when that item is also added, but is a separate feature)*\n\nIf set to ***Active***, the Properties will continue to function as it does today, only showing properties for the active item.\n\n## When there are multiple selected items\n\nWhen the user has selected multiple items, a few things change:\n\nInstead of showing the name of the object at the top, Blender tells the user how many items are selected:\n\n\nIn the list of tabs, only properties sections are shown that are common among the selected items. For example, if you select a text and a mesh object, we don't show Modifier, Mesh or Curve Properties, since these properties only exist on a subset of the selected objects:\n\n\nThis rule also goes for individual panels. Here, both a Sun and Spot light are selected, and we only see properties that are shared between them. A note at the bottom clarifies that you are only seeing the shared subset:\n\n{[F8364914](Screenshot_2020-02-23_at_18.49.33.png), size=full}\n\n## When values differ\nWhen multiple items are selected, Blender will compare values to check if they are the same, or if they are different. If they differ, we change the way properties are displayed, like so:\n\n{[F8363037](Screenshot_2020-02-22_at_17.52.51.png), size=full}\n\n\n\n## Manipulating values across multiple items\n\n\n\nFor simply setting a value to be the same. you would simply type a new value, hit Return, and that value is then propagated to the selection.\n\nFor manipulating numbers and sliders relatively, you can just drag on them (like Alt-dragging today), or type the character '=', so the user can type '= -3' to subtract 3 from the value on all selected items.", "Sculpt Mode Multires Design\nThe purpose of this task is to describe the main uses cases and functionality that should be provided by a Multires sculpting system, as well as to discuss a plan on how to implement that in Blender.\n\n\n## The main use case of Multires\n\n### The problem Multires solves\n\nWhen you are working on any art medium (this also applies for painting), you should always try to work from the general shapes to the details. In case of digital sculpting, this means that you should always try to work with the minimum number of vertices that represent the level of detail you are trying to add to the model.\nThis is also true for the current workflow we have implemented (The Voxel remesher). By default, it provides a low poly mesh (about 10K vertices), that you should deform trying to get main shape of the object you want. After that, you increase the resolution of the remesher until you have enough vertices to represent the next level of detail you want to work on, and you continue from there.\nThe reasons you want to work this way are:\n\n- Performance: It is faster (more responsive, without lag) to deform a mesh with 10K vertices than a mesh with 25M vertices. If you use a big brush size needed to modify the object proportions on 25M vertices at the same time, it is going to lag. (Unrelated note, but we should not try to optimize Sculpt Mode to support these kind of operations as they don’t make any sense with a Multires system in place).\n\n- (Most important) Noise: If you sculpt with more vertices than needed for the size of details and shapes you are trying to get, you are going to end with a lot of uncontrolled shape noise produced by the tools. This is not a specific problem with Blender brushes and tools, this happens in any software and in every sculpting system. If you use the Draw brush to add some volume on a big area directly onto a 25M vertices mesh, you are going to need need to clean manually all small uncontrolled imperfections that big stroke stroke produced if you want that to be the final surface. If you start sculpting from a sphere with 1M vertices, you are going to spend more time cleaning shape noise than sculpting or the sculpt is just going to look bad. This is why nobody works this way. You don’t generate unintended shape noise if there aren’t enough vertices to represent it.\n\n\nThat is the main problem Multires sculpting solves. With Multires, you are able to choose at any moment the level of detail that is appropriate for the change you want to make in you model, solving both the performance and the noise issues. This gives an artist a huge amount of freedom as you know you can always go back to tweak low frequency details (proportions, general volumes) after sculpting mid/high frequency details (wrinkles, skin alphas...) if you consider that they don’t look right, without loosing any work.\n\nWithout this, the rest of the sculpting workflows (the Voxel remesher, Dyntopo) are the same as sculpting with real clay or marble, you can only sculpt bigger first shapes, then mid details and them the small details. If it does not look right, there is not way to fix it, you need to delete what looks wrong and start again. This is why those workflows are often used for concepting general shapes, and you want two switch to Multires as soon as you can. Sculpting a complex model without using Multires, on any software, is extremely (and unnecessarily) hard and it requires an insane amount of skill from the artist to workaround the limitation. It is like sculpting without using undo. It is too risky to create a high poly sculpt with projected alphas without this feature.\n\nIn order to solve this problem, the main thing Multires needs to guarantee is that when you sculpt shapes on your model in the appropriate resolution level, all the other levels are updated accordingly to reflect the changes you did. This is what people often refer as ¨detail propagation¨.\n\n### Multires Design\n\nWhen designing a sculpting Multires system that provides the previously mentioned functionality, We need to take the following points into consideration:\n\n1. All Multires subdivision levels contain valid information (sculpted shapes, mask, colors...) that should never be lost or damaged. \n\n2. The user wants to modify any subdivision level, at any time, without restrictions (there should not be limits of how much the mesh should be deformed or “not allowed modifications”).\n\n3. The user wants to delete and rebuild higher/lower subdivision levels in he/she considers that the shape information that level contains is not longer relevant. \n\nFor example, if the user wants to do a high poly sculpt, he/she switches to the higher level subdivision possible that the computer allows to create the high frequency detail projecting alphas. When that is done, the user may want to switch to a lower level to tweak proportions, or to a mid level to tweak small volumes with a soft brush. All the work the user put into applying the alphas should be propagated with the lower subdivision level changes with the Multires functionality and the model should look fine.\n\nIf, for some reason (a bug or an design issue in the implementation that did not consider point 1), switching and modifying lower levels may introduce mesh artifacts in the higher ones (the ones that contains the alpha projections and high frequency details), it will destroy all the work done previously by the user in that levels. \n\nIn that case, the user is again limited to not going back to select the mesh resolution needed for the modifications he/she wants to make in the mesh. A Multires system like this is not solving the intended problem and there is no reason to use it. It provides the same functionality as any of the other sculpting workflows (Voxel, Dyntopo), but even more limited as the user can’t modify the base topology to adapt it to a new shape. It does not have any reason to exist.\n\nIf you project requires you to use a fixed predefined topology in your model (for animation, for example), subdividing the mesh manually and deforming it with a cage or a datatransfer provides the same functionality. You can also get a lower subdivision level by duplicating the model and using unsubdivide if you need it for texture baking or animation. This is not the main problem Multires should be trying to solve.\n\n \n**Any unwanted mesh artifact in the detail propagation, no matter how small it is, invalidates all Multires sculpting features and makes it not functional for its intended use case, as it leads to irreparable data corruption.**\n \n\n### Current Multires Modifier\n\nConsidering the previously design and use case description as valid Multires sculpting system:\n\n1. Multires in 2.81 does not support switching levels. This invalidates the feature completely and makes it not functional, but prevents the users to corrupt the mesh data if they use it. This is like not having Multires sculpting at all.\n2. Multires in 2.80 creates artifacts and vertex explosions when modifying any level, creating irreparable mesh data corruption. Releasing Blender with Multires in this state and without any visible UI warning could have destroyed the projects of many users in an irreparable way. Luckily, most users were not using it to create their models in the previous versions because it was also not working as intended. \n3. Multires in 2.79 and before creates a visible grid pattern on higher levels when modifying lower ones. This introduces unwanted shape noise and effectively destroys valid sculpted information, making it not functional for its intended use case. Users are limited to work considering of how much they can deform lower levels by the amount of noise they are predicting Multires will produce in the higher ones. This is not something that should be happening in a production ready implementation of the feature.\n\nThe most advances tools Blender has right now that were added in the last releases (Quadriflow, Elastic deform, IK Pose brush...) are designed to work with a Multires system:\n\n- The main purpose of Quadriflow is to produce subdividable geometry for a Multires. When you are done sculpting with Dyntopo/Voxel remesher, where you can’t have the freedom to choose the level of detail you want to work on, you can quickly generate a base mesh, subdivide it and reproject the details back. That way you can tweak again general proportions and low frequency detail.\n\n- These brush tools are designed to tweak proportions/big shapes of models, which is something you most likely want to do after sculpting more detail to have an idea of how your model looks like. Multires solves that problem.\n\n- These brushes can’t be used directly on high poly meshes. These tools needs to have disabled some sculpt mode optimizations in order to work, so they are much slower than regular brushes. In fact, if you try to use the IK pose brush directly on a high poly mesh, most likely you are going to run out of memory. If you don’t, it is going to create terrible artifacts between each segment. In order for these brushes to work as intended on high poly meshes, you need to use Multires to switch to a lower level, use the brush, and then switch to a higher level again to get the intended result.\n\n## Multires implementation reference\n\nSculptGL contains a valid and functional Multires sculpting implementation. You can try it by sculpting different details at different levels and switching between them, as well as creating and deleting subdivision levels:\n\nsculptgl/\n\nThis implementation of Multires provides:\n\n- Detail propagation that works across all levels. You can choose the desired level you want to sculpt on and that deformation is propagated correctly to all subdivision levels. There are not visible artifacts of any kind.\n\n- You can both create and delete levels in both directions (higher levels and lower levels) with subdivide/delete higher and reverse/delete lower. \n\nThese features are the minimum and required a Multires implementation in Blender should provide, as they are pretty much the definition of a Multires sculpting system. Any other Multires related feature or optimization (being part of the modifier stack, baking, shape keys, layers, exporting, reprojection, tool compatibility, Quadriflow...) should always come later. There should not be a design decisions that prioritize any other Multires feature or optimization without having those minimums perfectly working, bug free and functional.\n\n\n## Proposal\n\nGiven the fact that, as described here, Multires was never a functional feature for its intended purpose and:\n\n- The code is extremely hard to read and maintain. I still can’t understand what it is doing in some places or what was the reasoning to make it work that way in the first place. \n- New features are planned that require Multires support (masking tools, vertex colors, visibility operators). Adding Multires support for those features should not be a project bigger than the feature itself. This was the case with most of the 2.81 tools, and probably with the future planned features (Sculpt vertex colors or visibility management, for example)\n- We already have and sculpt tools abstraction layer in place. Making changes on the underlying data structures of sculpt mode should be easier than before\n- The original Multires comes from before 2.5. The basics of how it should works were never correct and a lot of features and modifications were added during the years. We are now trying to build state of the art sculpting features on top of a broken foundation that has more than 10 years. \n\nSome options are:\n\n\t- Replace Multires modifier with a simple implementation based on the SculptGL code (something we know it works) and start again from there. We can keep the current Multires modifier for compatibility, but we need to evaluate if supporting the features and fixes described in this task on the current code (and make it work exactly as the SculptGL Multires) is going to take more time than implementing something based on the SculptGL code from scratch. We also need to look that the new features that are planned and evaluate how hard they are going to be to add to the current Multires code (colors, per face data...) knowing that the SculptGL implementation already supports them.\n\t\n\t- Try to add this functionality to the current Multires modifier. In that case, the priority should always be supporting the functionality described in this task first, and the bring all the rest of the features back. In that case, it would be needed better documentation and code organization to be able to integrate new features into it easily.

It serves as an example of a feasible real-world application which would be broken by this kind of behaviour. Perhaps the original vertex weights act as a sort of base heightmap for a terrain model, and the changes made by the Subdivision and textured VertexWeightMix modifiers add an extra layer of detail. In this case, the clear and useful behaviour would be for behaviour to be continuous in the transition from 0.01 to 0.00.

I checked the face count and it was just 150k faces which is not a lot at all. It's definitely a modifier problem because when I apply the subd modifier the lag goes away completely even when sliding twice the amount of edges around. I thought that was maybe a hardware issue so I opened task manager and while sliding edges with subd on I get like 4 fps with severe stuttering to top it off. All that while the cpu was at 10% usage and 5% gpu usage with memory barely touched (6gb used out of 64gb). I have nothing else running in the background like an ativirus or music app, I have the latest version of windows 10, latest gpu and chipset drivers, latest bios etc... I even have gpu subdivision enabled without autosmooth to make sure it actually works properly. I even run an sfc/scannow to check for other kinds of issues but nothing changed. Subd in edit mode however is not only slow when sliding edges and vertices but also in adding loop cuts or insetting faces. It is extremely frustrating so it would be great if you could fix this. I know edit mode was not made to handle massive polycounts but 150k is again not a whole lot and definitely comfortable to run on my PC.

Why not support passing in a bounding box & return it's result, or a polygon and return the lasso result?\n\n *This could be handled as a separate step, mentioning it here to note that it's a possibility but not part of this proposal.*\n\n- We could return an object that stores multiple values, this means if we need to add additional context to the result, it wont break scripts.\n\n```\ne.g: \n```\n\n```\n result = context.region.find_on_screen_node(location)\n if result:\n print(\"Found\", result.node, result.node_group)\n\n```\n\n\n### Scope\n\nWhile this need not implement all data-types initially, these are data-types that could be supported.\n\n- 3D View\n\n - Objects (all types)\n - Armature Edit Mode: Bone, Head/Tail\n - Armature PoseBones: Bone (only)\n - MetaBall: Inner / Outer rings.\n - Mesh Elements: (Vert/Edge/Face)\n - Curve: Vertices & Handles\n - Lattice: Vertices\n - Grease Pencil: Vertices\n - Particle Edit Mode: Vertices\n - Stroke path bezier handles.\n - Gizmos? *(not sure about this one)*\n\n- Image View\n\n - UV Elements: Vertex, Loop, Face\n - Mask: Vertices & Handles\n\n- Node Editor\n\n - Nodes\n - Node Sockets\n - Node Links?

Create a scene in Cycles.\n2. Change to the rendered viewport.\n3. Open a shader editor and change to the `World` shader and delete the `Background` node.\n4. In the `World Shader`add a `Magic Texture` node and connect one of the outputs to the `Volume` socket on the `World Output` node.\n5. You will noticed that in the viewport you can see the `Magic Texture` is projecting light onto objects in the scene, but you can't see the `Magic Texture` directly.\n6. Place a `Color Ramp` node between the `Magic Texture` and the `World Output` nodes. Now you can see the `Magic Texture` in the viewport.\n\nAnother test:\n1. Create a scene in Cycles.\n2. Change to the rendered viewport.\n3. Open a shader editor and change to the `World` shader and delete the `Background` node.\n4. Add a `Noise Texture` node and connect an output to the `Volume` socket on the `World Output` node.\n5. Notice that you can see the impact the `Noise Texture` is having on the scene, but you can't see the `Noise Texture`\n6. Place a `Color Ramp` between the `Noise Texture` and the `World Output` nodes. You still can't see the `Nosie Texture` in the scene.\n7. Place a `Volume Scatter` node in the `World Shader`, connecting the output to the `Volume` socket on the `World Output` node and connect the output of the `Color Ramp` node to the `Density` input of the `Volume Scatter` node. You can now see the noise texture in the volume if you have a light in your scene.\n8. Select the left most handle (the handle that is black) in the `Color Ramp` node and drag it closer to the position `0.5`. You will see the results you expect until you reach the position `0.5` where the volume will seem to disappear from your scene. Yet when you look at objects in the scene, the light reaching them is still affected by a volume shader you can't see.\n\nHere's a video demonstrating this:\n[Volumetrics not visibile in viewport in certain sitautions.mp4](Volumetrics_not_visibile_in_viewport_in_certain_sitautions.mp4)", "Cycles: Caustics don't work when volume boundary between casting and receiving surfaces\nOperating system: MacOS, Windows\nGraphics card: Apple Silicon, Nvidia RTX3090\n\nBroken: 3.5.1, 3.6 Alpha\nWorked: -\n\nWhen there is a volume boundary between a caustic casting and receiving surface, the caustics vanish. \n\nOpen the attached .blend file.

The duplication automatically selects the new object in the 3D viewport but this selection differs from that shown in the outliner. This means dragging to, say, a new collection does not work as expected (only the parent object is moved leaving the child behind).\n\nThe set up (this is the attached blend file):-\n1. Create two cubes (or any meshes) and parent one to the other to form a hierarchy.\n2. Add the object(s) to a collection.\n3. Create another top level collection which is empty.\n\nThe aim:-\nTo duplicate the object(s) (not the collection) and copy the duplicate to the second (currently empty) collection.\n\nThe steps:-\n1. Right click the parent object in the outliner and choose \"Select Hierarchy\". Note that the outliner shows the selected objects with a blue background bar (as expected).\n\n2. In the 3D viewport, use Shift or Alt D (doesn't matter which) to create new duplicate objects. Note that the 3D viewport shows the duplicate parent and child selected. The outliner shows a new object selected (with blue bar) but the tree is collapsed so we can't see the child.\n\n3. In the outliner, click and drag the selected parent object to the empty collection. Note that only the parent moves, the child is left behind. This child has then to be dragged separately.\n\nAfter step 2, every visual cue leads the user to believe that the duplicate hierarchy is selected. And this is the intuitive behaviour expected. But expanding the outliner tree shows the child object is not, in fact, selected (no blue bar). So an additional step of having to reselect the hierarchy is required before step 3.\n\nThe main issue is that with lots of objects and detailed hierarchies, just forgetting that additional \"select hierarchy\" step before dragging means that child objects can be scattered all over the place away from their parent and the user is left picking through the large list trying to sort it out.\n\nThis may not be a bug, it may be working as designed. But I cannot think of a use case where the current functionality would be useful so I'm assuming it's a small selection bug.\n\n", "Shader color affects Shadow Pass in Cycles\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080 Super with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.68\n\nBroken: version: 3.1.0\n\nShadow Pass is not working as it should in Cycles.

The general goal is to bring those operations back to a constant (`O(1)`) or logarithmic (`O(log(N))`) complexity.\n\n**Description**\n**Use cases:**\n*Need specific test cases.*\n* Undo changes in object mode in a heavy scene.\n* Undo changes in pose mode in a heavy scene.\n* Duplicating objects in a heavy scene.\n* Adding many objects in a scene.\n\n*Note:* There are two types of “heavyness” in scenes (that can be combined of course):\n * Scenes that have many objects and/or collections.\n * Scenes that have very heavy geometry, either in the geometry data itself, or generated from modifiers like subdivision surface.\n\n**Design:**\n # Dependency graph should not have to re-evaluate objects that did not change.\n ** This is mainly a problem currently during global undo, as all data-blocks are replaced by new ones on each undo step.\n # Handling naming of data-blocks should be `O(log(N))` (it is currently close to `O(N²)`, or `O(N log(N))` in best cases).\n **This will require caching currently used names.*** We will probably also have to handle smartly the numbering in that cache, if we really want to be efficient in typical “worst case” scenarii (addition of thousands of objects with same base name e.g.).\n - Caches/runtime data helpers should be always either:\n - Lazily-built/updated on-demand (code affecting related data should only ensure that the 'dirty' flag is set then).\n *** This approach can usually be easily managed in a mostly lock-less way in a threaded context (proper locking is only needed when actually rebuilding a dirty cache).\n ## Kept valid/in sync all the time (code affecting related data should take care of updating it itself, code using the cache can always assume it is valid and up-to-date).\n ***Such cache should be easy to incrementally update (it should almost never have to be rebuilt from scratch).****This implies that the cache is highly local (changes on a data-block only ever affect that data-block and a well-defined, easy to reach small number of “neighbors”).*** In general keeping this kind of cache valid will always be harder and more error-prone than approach #A.\n *** This approach often needs proper complete locking (mutexes & co) in a threaded context.\n \n *Note: The ViewLayer's collections/objects cache e.g. currently uses the worst mix of #A and #B - it is always assumed valid, but updating it requires a complete rebuild from scratch almost all the time.*\n\n *Note: Approach #B is usually interesting only if a complete rebuild of the cache is **very** costly, and/or if the cache is invalidated very often while being used.*\n\n**Engineer plan:** `-`\n\n**Work plan**\n\n**Milestone 1 - Optimized per-datablock global undo**\nTime estimate: `6 months`\n\n* Re-use as much as possible existing data, and try to swap newly read (modified) data to the original memory, during 'memfile' undo step. Updating the depsgraph should then be much less work.\n** #60695 (Optimized per-datablock global undo)\n** [D6580: WIP/Demonstration patch about undo speedup project.](D6580)\n\n**Milestone 2 - Lazy collection synchronizations**\nTime estimate: `1 month`\n* Fix view layer collection syncing (to not require looping over all objects, or to be ran much less often...).\n** #73411 (Fix ViewLayers cache building)\n\n**Milestone 3 - Data-blocks management performances with many of them**\nTime estimate: `5 months`\n\n# Investigate how to best handle naming conflicts issues.\n**Most obvious idea would be store all used base-names in a GHash (one per ID type), along with used indices. Needs further design though.** #73412 (Improve name conflict handling in ID management)\n# Investigate the best way to cache bi-directional relationships info between data-blocks.\n**We already have a start of this with `BKE_main_relations_create()` & co, but it is heavily under-used and needs better design to be usable more widely.** #73413 (Cache data-block relationships info )\n# Fix/Improve handling of the Bone pointers (which are sub-data of `Armature` ID) stored in poses (which are sub-data of `Object` ID).\n**Ideally such horrible pointers should not exist ever. They are a very solid recurrent source of bugs in Blender.** Not sure how to best deal with them, at the very least we could add some generic ID API to ensure those kind of caches are up-to-date?\n\n\nSee also #68938 (Blender editing performance with many datablocks).\n\n**Later**\n\n* Dependency graph rebuild to be `O(1)` or `O(log(N))` (it is also `O(N)` at the moment). *???? would assume linear would already be nice performance for such a code?*\n\n**Notes:** -\n\n---\n", "Blender full crash during smoke+noise baking \"EXCEPTION_ACCESS_VIOLATION\"\nOperating system:

This could mean that GPU textures could be shared, until the user starts modify-ing one.\n* GPU textures for movies and sequences can only be shared when they reflect the same frame number. Currently a eevee cannot handle drawing multiple frames from the same image data-block. A work around for this is to duplicate the image block. For the short term we could also not support sharing GPU textures for movies and sequences at all as this isn't used that much to our knowledge.\n* Both single tiled and multi-tiled images should be supported.\n\n## Implementation\n* Use a single GPUTexture cache. Store GPU textures with a key. Key could be some values stored as a string. Per key a group of GPU Textures can be retrieved (Tiled, TileIndex, Image, left/right) etc.\n* Additional benefit is that usage tagging can be done faster as we don't need to go over all the image data-blocks in the scene.

We import bpy in the main process\n> 2. This brings in the `C:\\Users\\TGubs\\Code\\Python\\blender_test\\venvs\\3.6.832\\Scripts\\2.79\\scripts\\modules` to the top of sys.path because the Blender runtime needs it\n> 3. The `multiprocessing.Pool` instantiation grabs our bad `sys.path`\n> 4. Since modules aren't portable across the `multiprocessing.Queue` our new processes are going to try to import the modules again\n> 5. Search along `sys.path` for `bpy`: I found one at `C:\\Users\\TGubs\\Code\\Python\\blender_test\\venvs\\3.6.8-32\\Scripts\\2.79\\scripts\\modules`!\n> 6. Error: can't locate or import its dependency `_bpy` (mostly because that is a Blender runtime convention that does not apply in Python)\n\n\n\n## Hacky Workarounds\nI also found a couple of hacky workarounds:\n1. backup `sys.path` before `import bpy`. And restore it right before instantiating the multiprocessing object. Once done, revert your change. [Code](23#issuecomment-514826760), or\n2. guarding the `import bpy` to avoid re-importing it:\n\n```python\nfrom multiprocessing import current_process\nimport multiprocessing as mp\n\nif current_process().name == 'MainProcess':\n import bpy\n\n\nif __name__ == \"__main__\":\n manager = mp.Manager()\n```", "Can't Animate Texture Mapping Offset For Particle Hair\nWindow 7 64bit 8gb\nnvidia 660\n\nBroken: 2.72 RC\nWorked: I thought this was possible all the way back into the 2.4 series.\n\nAdd a single keyframe to particle texture mapping coordinates.\nMove to another frame and type a new number in the *Offset* mapping field and it will jump back to the number of the first keyframe.\nIn this state there is no way to animate the*Offset*.

Maybe a complex procedural texture, static background or ray-traced AO/curvature.** Light maps may also be considered part of this, though I personally would not recommend to use them for Cycles or Eevee and not focus on this use case.\n* One-off bakes\n**Examples may be to create a base to start texture or vertex painting, to use in geometry nodes, etc.** The current workflow is reasonably well suited to this, but automatic creation of images or vertex color layers and preview of the result would be helpful.\n** Perhaps best integrated as an operator/tool in paint or edit modes.\n* Other\n**Light map baking for export: how important is this still in modern game engines?** Baking as a part of a geometry nodes network?\n**Baking to transfer attributes between objects: use Data Transfer modifier instead?** ... ?\n\n### Proposal\n\nThere is not a single workflow that is ideal for all uses cases. I suggest to have two workflows that I think will handle the most important ones well, and can work for others with some extra effort. The Bake panel in the scene render properties would be removed.\n\n**One-Off Bakes**\n\n* New operator to quickly bake to images or attribute\n* Operator pops up a dialog, with choice for bake type and relevant settings\n* No settings stored in the scene. Only operator properties, remembered for the next operator execution\n* Operator creates new images or attribute if none exists, or bake to active one\n* Likely exposed in vertex, sculpt, texture paint mode, and in the vertex colors panel\n* No selected to active baking support here\n\n**Material Based Bakes**\n\n* New Bake Texture shader node\n**Bake type and relevant settings** One bake type is an input socket with arbitrary shader nodes plugged in\n**Image or attribute to bake to** Bake/Clear button\n* New Material datablock settings\n**Bake panel in material properties shader node editor, visible when there are any Bake Texture nodes** Bake/Clear button for the entire material\n**Collection property for \"selected to active\" baking, no use of selection state.** Any other shared settings\n\nWith this system, it's possible to create a reusable shader node group for a baked material, or manually add a few Bake Texture nodes for specific cases.\n\nA big advantage of this approach is that the baked result is also immediately previewable in the viewport and usable in the final render. No need to set up bake settings in one place, and a preview shader node setup in another place.\n\nMore details to be worked out\n* Likely need an Image socket type, to make shader node groups really reusable?\n* How to handle baking multiple materials into one, special material slot that all materials bake into? \n** Potentially confusing to have two ways to bake, using either this special slot or as part of regular material slot\n* Precise workflow to clear bakes and decide if baked/unbaked is show in viewport and render\n\n### Python API\n\nWe expect add-ons will continue to be needed for more advanced use cases and automation.

I compare it to the Curve Deform modifier as an example of proper deformation. Now, you may say it's an unfair comparison given that curves have an explicit twist that you can modify, unlike hairs. But even without controlling the initial twist of the hair, it's broken in a couple of ways.\n\nFirst, it deforms the mesh unevenly, with some vertices twisting more than others, even in a case where vertices are completely equidistant around the origin and both origins are aligned, like the cube in this image. The selected face and the edgeloop here should be squares but aren't, unlike in the curve deform modifier \nSecond, when changing the length with the Position Slider, the whole thing seems to change twist at once. Instead of having a consistent twist on each point of the path [Particle Instance Mod bug2.mp4](Particle_Instance_Mod_bug2.mp4)\nAs a side note, when using Along Path, finding how to orient your mesh to the hair is unintuitive, always using the global Y axis as the length axis in which I added subdivisions but then twisting weirdly when changing the Axis option in the modifier, I settled for Z in this example.\n\n\nAttached is the same file used in the video, you can open it and move the Position slider in the Particle Instance Modifier, the scale of the Curve Deform modifier example is driven by it so you can see both changing in real time.\n\n[ParticleInstanceTwistBug.blend](ParticleInstanceTwistBug.blend)\n\nWhy do I think this is happening? Well, if you select the object with the particle system, go to the particle properties, and change the length of the hair under the Render>Timing>End subpanel, you can see the problem is the same, basically the twist changes with length. Maybe the modifier should do something different and get the twist from the whole length particle and then scale the mesh instance before deforming or something like that, idk\n\n", "Curves edit mode Bezier handle editing\n- [ ] Add handle selection attributes\n- [ ] Support handles in selection operators\n\t- [ ] Selection picking\n - [ ] Box select\n - [ ] Lasso select\n - [ ] Circle select\n- [ ] Support in transform operator\n\t- [ ] Take into account automatic and aligned handle types\n - [ ] Convert types when transforming with set handle positions node behavior\n- [ ] Add \"Set Handle Type\" operator with options for each handle type (no \"toggle free/align\" option)\n\nRealistically, adding proper support for Bezier curves in curves sculpt won't be feasible, as long as handles positions, types, and selections are stored in separate attributes.

In those cases the simulation inputs are used unmodified as simulation outputs.\n\n\nIf an iteration is computed during node evaluation then the simulation outputs are defined as follows:\n1. When cached data is available for the exact current frame the outputs simply expose the cached data.\n Simulation inputs are ignored.\n \n\n2. When cached data for the current frame is not available, but exists for an earlier frame, an iteration is performed with the necessary time step.\n Simulation inputs are ignored.\n Iteration inputs are cached data.\n \n\n3. When previous data is unavailable or invalid, then the current simulation inputs are used and piped straight to iteration inputs.\n This is only correct for the start frame (to keep results deterministic), so on other frames a warning should be shown if no cached input is available.\n \n\n# Invalidating Caches\nA cache becomes invalid if the scene data is changed such that the output for the current frame will be different. This could be because\n1. The simulation input on the start frame is different.\n2. Scene data used during the iteration (e.g. an Object Info node) changed.\n\nIn practice it will be difficult to determine precisely when changes do or do not affect the simulation. False positives have to be expected, that is: invalidating the cache when it wouldn’t have to be. This is because we have to rely on coarse depsgraph dependencies. It is preferable to invalidate the cache unnecessarily than to keep cached results and miss potential changes. Over time the dependencies affecting nodes may be refined for more stable caching.\n\n## Reset\nThe term \"reset\" describes the point when a simulation reverts to the initial scene data, typically when animation jumps back to the start frame (Point 3 in [Stepping](#stepping)).\n\nConditions that can cause a reset (only when cache is invalid!)\n* Jump to start frame\n* Jump to other frame, with a warning\n* Start frame is changed (might invalidate cache)\n\nA reset should not happen just because the cache got invalidated. For example: A particle simulation might use an object as emitter. The user moves this object manually during simulation, which constantly invalidates the cache. However, the particle simulation should not *reset*: all the current particles remain in the simulation.\n\nThe last valid simulation state is always retained even if the rest of the cache is invalidated. That way simulations can be tested dynamically.\n\n# Baking\nBaked caches are never invalidated automatically.\n\nIf a baked cache exists then the simulation input should never be used and no further iterations should happen. The simulation output is always read from the cache.\n\nA baked cache must be freed explicitly, at which point it reverts back to a dynamic cache.\n\n# Notes\n* “Memory cache” vs “disk cache” distinction should not be relevant to most of the examples below.\n* Undo is effectively a file load operation too.\n", "Support socket icons in the Group Sockets Input/Output type enum\n{[F10225900](image.png), size=full} (crude mockup)\n\nThe issue is that the socket colors are not icons, but maybe they should/could.", "Occasional render glitches when using simulation zones on an object without a material.\nThis bug has an easy workaround, mostly posting this so anyone running into the same issue knows the solution.\n\nOperating system: Linux-5.15.0-79-generic-x86_64-with-glibc2.35 64 Bits, X11 UI\nGraphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 530.30.02\n\nBroken: version: 3.6.2\nWorked: N/A, 3.6 is the first version with simulation nodes.\n\nIn Eevee, rendering an object with a simple simulation zone applied in geometry nodes and no material assigned to the object results in some rendered frames being blank or displaying odd glitches.\n\nThe workaround is to simply assign a material to the object.\n\nCheck out the attached .blend file for reproduction.\n\n", "Pose Library: Collection pop-up when creating new poses in Action Editor\nWhen creating poses from the Action Editor it should be explicit to which catalog the new asset should be added.\n\nBy default the Unassigned option should be highlighted, so users can post-pone this decision for later, similar to when marking data-blocks as assets.\n\nThis is part of #103265.\n\n---\n\nSome initial code snippets for anyone interested on tackling this: [P3408](P3408.txt)", "Allow changing the active modifier on linked objects\nUnzip the files from [active-modifier-linked.zip](active-modifier-linked.zip)\n\nOpen `linked.blend` and try to change the active modifer.

This could be controlled in the Properties like so:\n\n{[F8363009](Screenshot_2020-02-22_at_17.34.54.png), size=full}\n*(The search box is added here to reflect how the Properties will be updated when that item is also added, but is a separate feature)*\n\nIf set to ***Active***, the Properties will continue to function as it does today, only showing properties for the active item.\n\n## When there are multiple selected items\n\nWhen the user has selected multiple items, a few things change:\n\nInstead of showing the name of the object at the top, Blender tells the user how many items are selected:\n\n\nIn the list of tabs, only properties sections are shown that are common among the selected items. For example, if you select a text and a mesh object, we don't show Modifier, Mesh or Curve Properties, since these properties only exist on a subset of the selected objects:\n\n\nThis rule also goes for individual panels. Here, both a Sun and Spot light are selected, and we only see properties that are shared between them. A note at the bottom clarifies that you are only seeing the shared subset:\n\n{[F8364914](Screenshot_2020-02-23_at_18.49.33.png), size=full}\n\n## When values differ\nWhen multiple items are selected, Blender will compare values to check if they are the same, or if they are different. If they differ, we change the way properties are displayed, like so:\n\n{[F8363037](Screenshot_2020-02-22_at_17.52.51.png), size=full}\n\n\n\n## Manipulating values across multiple items\n\n\n\nFor simply setting a value to be the same. you would simply type a new value, hit Return, and that value is then propagated to the selection.\n\nFor manipulating numbers and sliders relatively, you can just drag on them (like Alt-dragging today), or type the character '=', so the user can type '= -3' to subtract 3 from the value on all selected items.", "History filled with \"Double click to

This works, but the connection is shown as error in red.\n\nIdeally \"Slice String\" would accept a field for \"Position\" and \"Length\", so arbitrary parts of the string can be extracted for each geometry duplicate. The output of \"Slice String\" should also be a field.\nI'm not sure if there's a way to handle this without an error in the geometry nodes.\n\nOverall, it seems Blender is lacking string-fields, because the \"Equal\" node also defaults to fields for all types except strings.

Texture nodes can be though of as a geometry nodes field, and when evaluated in the context of geometry nodes they are.\n\nHowever they can also be evaluated outside of a geometry node tree. In particular, they can be evaluated on:\n* Geometry domains vertex, edge, face, corner, for geometry nodes and baking of textures to attributes. Possibly also sculpting and vertex color painting.\n* Geometry surface, for image texture baking and painting.\n* 2D or 3D space not attached to any geometry. For brushes, 2D image painting, physics effectors.\n\nTo support the last two cases in the geometry nodes infrastructure (but not the geometry node evaluation itself), a new field context named `TextureFieldContext` is added. This represents a continuous texture space, that may be mapped to a geometry surface or not. It has one domain, `ATTR_DOMAIN_TEXTURE`.\n\n**Compilation and Execution**\n\nThe texture nodes compilaton and evaluation mechanism uses much of the same infrastructure as geometry nodes, but is separate to be usable in different contexts. It's meant to be possible to execute texture nodes efficiently many times, for example paint brushes are multi-threaded and each thread may execute the nodes multiple times. This is unlike geometry nodes where multiple threads may cooperate to execute nodes once.\n\nThe current compilation mechanism is as follows:\n* Multi-function nodes are compiled into a `MFProcedure`, which bundles multiple multi-functions into one for execution. Geometry nodes do not currently use this mechanism, but it is designed for this type of evaluation. This is rather inefficient currently for individual points, but should get more efficient when evaluated in big batches.\n* Remaining nodes are input nodes, and execute `geometry_node_execute` as part of compilation, which then outputs fields and values. The execution context for these nodes is limited, unlike geometry nodes there is no geometry, object or depsgraph.\n* For evaluation, fields are converted into `GVArray` using the provided geometry.\n\nWe could consider making geometry available and to the compilation and caching the compilation per geometry, though it's not clear there will be nodes that need this. Alternatively we may cache just the `GVArray` per geometry.\n\n**Fields**\n\nInput nodes return fields, which are then turned into `GVArray` for evaluation. For the texture domain, this is a virtual array that interpolates attributes. There may be some possibility here to share code with data transfer field nodes, or nodes that distribute points and curves on surfaces and inherit attributes.\n\nShader nodes need additional fields that are not currently in geometry nodes:\n* Generated / Rest Position / Orco\n* Normal, taking into account face smooth flag and custom normals\n* UV maps (planned to become available as float2 attributes)\n* Active render UV map and color layer\n* Tangent\n* Pointiness (Cavity)\n* Random Per Island\n\nIt's unclear to me what the best way to specify these as fields is, if we should add additional builtin atttribute names or `GeometryFieldInput`. Some of these like Pointiness would also make sense to cache as attributes, and make available to external renderers.\n\nOne constraint is that it must be efficient to evaluate only a small subset of the domain. For many field inputs and operations this works, but there are some that will compute a data array for the entire domain. This can be enforced by just not making such nodes available as texture nodes, or caching the data array on the geometry.\n\nFor sculpt and paint modes, there is a question if and how we can make all these attributes available. The challenge is that it has different mesh data structures (bmesh and multires grids), which are not supported by geometry nodes. Additionally, recomputing for example tangents and pointiness as the geometry changes during a brush stroke would be inefficient, especially if it's for the entire mesh and not just the edited subset.\n\n**Batched Processing**\n\nFields and multi-functions are not optimized for evaluating one point at a time, there is too much overhead. That means we want to process texture evaluations in batches, and all (non-legacy) code that uses textures should be refactored.\n\nFor geometry nodes, modifiers and 2D brushes this is most likely straightforward. However for 3D brushes, particles and effectors it will be more complicated.\n\nThere is currently a mechanism to single evaluations possible while code is being converted. However this is rather inefficient, with quite a bit of overhead in `MFProcedure` execution. It may be possible to do some optimizations there for legacy code that we may not be able to easily convert to batches.\n\n**Node Graph Transforms**\n\nTo support sockets like Image datablocks, and to automatically insert Texture Coordinate or UV Map nodes for textures coordinate sockets, we need to transform the node graph. The texture node layering will also need to do significant node graph transformations. In order to share code with Cycles and other external engines, it may be best to do this as part of node tree localization.\n\n**Relation to Other Node Systems**\n\nThere are many node evaluation systems in Blender, and the question is if we can somehow share this implementation with anything else. I don't think the CPU evaluation can be directly shared, but will make the old texture nodes evaluation obsolete at least. The GPU implementation can probably be largely shared with shader nodes, and that implementation could be refactored to use DerivedNodeTree for consistency and to simplify that code.", "Geometry nodes preview, clipping Region in the viewport its not working\nOperating system: Linux-5.15.0-58-generic-x86_64-with-glibc2.35 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.161.03\n\nBroken: version: 3.4.0 Alpha\nWorked: Never\n\nCaused by: c55d38f00b\n\nTo be compleatly honest i don't remember if this was a limitation of the preview node or not and i was unable to find the answer. \nSo as the title says viewport clip in viewport doesn't work in the geonodes overlay preveiw\n\n\n- Try to preview any data from geometry nodes. \n- alt+b to do a viewport clip\nshould look like in the left side of the image above, but it seems that a second geometry with the info from geo nodes in alpha blend mode its not being clipped \n\n" ]

More details would have to be looked into for an actual design.\n\n### Motivation\n\nLinking objects in Blender has the inherent design limitation that it also links the object's transform, which means you can't transform an object that was linked. This is a very basic and important operation. With library overrides, that issue is mitigated; however IMO we should look at this as a feature for production use-cases, not as something for more informal, low-overhead usages. This would be a complex solution for the user to manage for a simple problem. They need rather deep understanding of how Blender data-management works to manage library overrides.\n\nEspecially for the Asset Browser, it would be good to have a simple solution that behaves as users expect. Apparently what they do expect is that they can simply link objects, while being able to transform them still. Not being able to edit other object properties seems fine.\n\n### Possible Solutions\n\nFor collections we have actually addressed this issue by supporting linked collection instances. That means, while the collection and its contents are linked, the collection is placed relative to an emtpy that is local to this file. So by transforming the empty the entire collection is transformed. The idea of instancing can be brought to objects so transforming linked objects becomes possible in effect.\n\nSome ideas on how object instancing could be supported on linking:\n* **Object is made local, the mesh, materials, etc stay linked** Simple to implement - downside is that object properties, modifiers, constraints, physics and the like would not be linked anymore.\n* **Instancing via empty.** This would be very similar to collections. An empty can instance an object which means it acts as a parent of the object.\n* **Wrap into collection instance.** Effectively the same as instancing via an empty, but the user would see an intermediate collection. It's simple to add this, but kind of forces an implementation detail onto users.\n\n### Other Approaches\n\nInstead of trying to support object instancing, other things could be done on linking:\n* **Automatically create library overrides for transforms**. Another simple solution technically and at least saves the user from having to know about or setup the library overrides when linking. But obviously pushes users towards using library overrides, which they sooner or later will still have to deal with.", "Geometry Node: New Sample Curve\nAdding support for a random attribute to the sampling node exposed the problem of attribute evaluation ignoring the calculated curve. This design variant is intended to treat the sampling of values from calculated curves as a new attribute-based сontext.\n| [2022-08-01 14-00-56 (video-converter.com).mp4](2022-08-01_14-00-56__video-converter.com_.mp4) |    |\n| -- | -- |\nThe crux of the problem is that a random attribute, when sampled, must be able to have a position behavior. Other behaviors are not covered yet, but may be added later.\nSampling attributes do not belong to the curve and have their own size. Their interpolation may not be linear, but based on the type of curve, which increases the speed for large objects.\n\nExample: sampling a random vector from curve points. You want the vector to keep its length. But even the original implementation of normals kept the length just because of the normalization. Nonlinear interpolation in spline space for a vector has the ability to rotate it without loss of length and incorrect deformations.\n\nOr you want to sample a color. You can set the color for the breakpoints and... Whoa, those are just linear transitions! Handles cannot be used. They are not a domain and this design does not violate that. Simply by sampling an attribute, you can sample it not only from breakpoints, but from handles!\n\nAlso, in addition to entering an attribute as the domain of the sampled curve, a segment data node is offered. This low-level node is for primary access to cache data. The sampled attribute input node uses this as its signature. But it can also be useful for the user to be able to use this data, for example, to visualize the operation of a bezier curve.\n\nWhen sampling, 3 types of values must be present in the scope of the context:\n - Curve data obtained from the visible version of the curve\n - Curve data sampled from its points and handles\n - Sampling destination data. To keep things simple, if multiple post-sampling values are going to be used with geometry definitions, it's best to do this before the sampling node to keep the output of the node to a minimum.\n\nAlso sampling features:\n1. The option of sampling a vector in normal/target space + sample position can be used as a variant of the curve mesh deformation\n2. Sampling at an arbitrary point creates freedom to obtain information about the curvature of the surface.\n\n---\nCurve Input:\n - Spline type (Select current type curves / index of type)\n - Select Spline By Type (By type index)\n\n---\nChanged Nodes:\n - Sample Curve\n - Input:\n - Curve\n - Factor / Length\n - Curve (Index)\n - Attribute (Random type) (use SampleCurveContext)\n - Output:\n - Value (Random type)\n```\n\n```\n - Position:\n - In SampleCurveContext return evaluated_positions\n - Normal:\n - Same Position\n - Curve Tangent:\n - Move TangentFieldInput to Fields Input and add it in SampleCurveContext same position\n - Index:\n - Same position.

But there are plans to extend this to:\n* Drag & drop\n* #68933 (Collections for Import/Export)\n* Geometry nodes\n* Asset system\n\nFor this we need a unified system to handle I/O for various file formats, to provide consistent functionality across these areas and avoid code duplication.\n\nIt will also make a better user interface for the import operator possible, with a single `File > Import` menu entry where you can then pick a file and see the appropriate options, without having to determine the file format first. Drag & drop similarly should be able to recognize the file type automatically.\n\n## Design Proposal\n\nAdd new `IOHandler` type that can be subclassed, similar to operators or render engines (maybe a better name can be found).\n\nIt would include:\n* List of file extensions (or method to determine if a filepath matches)\n* Method to create import / export settings\n* Method to make UI layout of import / export settings\n* Method to import a file\n* Method to export to a file\n* Method to provide metadata about file\n\nThe precise functionality needs to be determined by looking at the various use cases. But a few general points:\n* Settings:\n**Can be stored as ID properties.** Potentially the defined properties may depend on the use case, for example an import operator may have additional properties relating to how it affects the scene, compared to collection I/O which may be more local.\n* Import:\n** This could work similar to library linking .blend files. That is, importing would populate its own main database with datablocks. The operator, geometry node, assets system would then receive this main database and use, copy or link the datablocks as appropriate for each. This gives each use case more control over the ownership, and by not affecting the main .blend database there should be no side effects from running the import method.\n* Export:\n**Exporters typically export depsgraph evaluated scene data. They also have options for exporting only selections or the entire scene. There is some potential here for an abstraction that provides the relevant subset of evaluated scene data to the exporter, but the right API for this is not obvious.** On the other hand for syncing with Omniverse or other collaborative tools, the data you import and export needs to match, so then you might be exporting original scene data? This might be something we do for USD only and after the basic I/O handler is in place, it's unclear if this would be part of the same system and how it would fit in.\n* Assets:\n**Currently assets must always be datablocks from .blend files, but ideally any importable file would be indexable by the asset browsers as well. For this it's important to be able to quickly read metadata, maybe read or generate a preview image.** Being able to get the file as a set of datablocks in a database could allow reusing existing code more. Even image files could be read as an image datablock for example. However the asset system might already have plans for its own abstractions here, we need to check how it fits.", "Toggle to Edit Mode call error when the Blender use linked a object data from another file\nOperating system: Linux 5.10.2\nGraphics card: Intel Haswel (4-th Gen ) HD Graphics 4600\n\nBroken: 2.92\n\n\nToggle to Edit Mode call error when the Blender use linked a object data from another file\n\n\n1) Create any object in a scene and save this file \n2) Create a new blend file and link the object from previous saved a file with `File` → `Link..` and then select this object.\n3) Then convert linked object to local object with `Object` → `Relations` → `Make Local...` → `Selected Objects`\n4) Select the object and press Tab that go to Edit Mode. \n5) Error - Unable to execute 'Toggle Editmode', error changing modes\n\nor download both files and then open linked.blend:\n\n[source.blend](source.blend)\n[linked.blend](linked.blend)\n\n", "Library Overrides: Making an override (for a linked object in the scene collection) creates a duplicate object\nOperating system: Linux-6.1.18-200.fc37.x86_64-x86_64-with-glibc2.36 64 Bits, WAYLAND UI\nGraphics card: AMD Radeon Graphics (renoir, LLVM 15.0.7, DRM 3.49, 6.1.18-200.fc37.x86_64) AMD 4.6 (Core Profile) Mesa 22.3.7\n\nBroken: version: 4.0.0 Alpha\nWorked: --\n\nLibrary Overrides: Making an override (for a linked object in the scene collection) creates a duplicate object\n\n- open `main.blend`\n- (there is a linked object in the scene collection)\n- `Object` > `Library Override` > `Make`\n- A separate (overridden) Cube object is created in the scene collection (along with the linked object still there)\n\nNOTE: doing the same from the Outliner (RMB > `Library Override` > `Make` > `Selected`) seems to work as expected\n\nas a comparison:\n- open `main_with collection.blend`\n- (there is a linked object in a collection [not the scene collection])\n- `Object` > `Library Override` > `Make`\n- The overriden Cube object is just there without the linked object Cube being present\n\n", "ID Deduplication on Append - UX \nThis task is about which behavior should be default when linking/appending IDs, and assets, and how much/how users should be able to customize those behaviors.\n\nNOTE: Currently this is mostly listing topics to be discussed.

Options are to toggle the mode or cycle through sub-modes. Both have their pro's and con's so there are no plans to use second-time presses.\n\n**Is overwriting edit-mesh modes acceptable?**\n\nBy switching directly into vert/face/edge modes, this will overwrite the mixed modes which the user will need to manually set every time they enter edit-mode. Holding Shift while changing selection modes will extend the selection as it does currently.\nEven though this isn't such a common functionality, it would be good to avoid breaking peoples workflows.\n\n----\n\n*Updated by @pablovazquez based on notes from the UI meeting on 20 May.*", "Geometry Nodes Baking\nAs mentioned on the [blog]() the goal is to support the following features:\n* Editing procedurally generated geometry destructively in the viewport.\n* Prepare and manage simulations for the render farm which shouldn't need to run the simulation itself.\n* Explicitly cache parts of the node tree to avoid recomputing them after every change.\n* Re-time animated geometries, i.e. access geometry generated on one frame in another frame.\n\nAt a high level these goals are achieved by allowing the user to bake still or animated geometry at arbitrary positions in a geometry nodes tree using a new Bake node. The baked data can then be used without having to recompute the inputs of the Bake node. It can be edited destructively using Blender's existing edit modes. Furthermore, the baked data can be imported at specific frames.\n\nImplementing all of these features in one go would be too big of an undertaking, so below are smaller releasable milestones that can be worked on one after another.\n\n## Milestone 1: Bake Node\n\nAfter this milestone users will be able to bake still or animated geometries at arbitrary positions in the node tree. The main use cases are:\n* Prepare simulations (with optional post-processing) for a renderfarm.\n* Speedup working with very heavy node trees (e.g. static landscape generation) by explicitly caching the generated data.\n\nThere are a few requirements for this milestone:\n* New Bake node with a dynamic number of sockets for geometries and their attributes.\n* Baking works by pressing on a bake button in the node itself.\n * For baking the user has to choose between still or animated geometry and optionally a frame range.\n * A bake directory on disk has to be choosen.\n* Deleting the baked data should be possible from the node as well.\n* Potential settings and the baked data are stored per Bake node instance. A Bake node that is in a reused node group is counted as multiple Bake node instances. The actual data per Bake is stored in the geometry nodes modifier on the object.\n\nIt may be enough to keep UI changes local to the new Bake node.\n\n## Milestone 2: Manage Bakes\n\nIn production files, there are typically many simulations and other heavy effects that require baking. The goal of this milestone is to give the user tools to manage many bakes.\n\nThere are multiple parts to this which could potentially be split up into somewhat independent tasks, but I keep them together until further discussion happened:\n* Support naming Bake node instances.\n * While working with just Bake nodes in the node tree, this is less important, because the location of the Bake node in the tree \"identifies\" it to the use. When dealing with many Bake node instances at once, one can't rely on their location but needs to use names.\n * Just using node names does not work well for this, because a node only has one name but might be reused many times.\n* Support tagging Bake node instances.\n * As we've seen in the intro, not all baking happens for the same reasons. Therefore it is important that tools that work with multiple bakes can filter what bakes to work on.\n * Supporting custom tags can help the user organize baked data.\n* UI for dealing with all bakes in a scene or file.\n * There should be some kind of UI list that shows all the Bake node instances.\n * It should show which data is currently baked and which not.\n * Filtering can happen using tags and object selection.\n * Various new operators can work on multiple bakes at the same time: bake, delete bake, set bake directory.\n* Python API for dealing with baked data.\n * While the UI we provide for managing baked data should be good enough for most use cases, it seems unrealistic that we can provide all the tools that a larger production needs out of the box. Therefore, it is necessary to make it easy to manage bakes from addons as well.\n\n## Milestone 3: Import Bake\n\nThe Bake node does two things implicitly, it indicates where in the node group the baking happens and it also imports the baked data. Having both of these in the same node is desirable for most use cases, but sometimes it's benefitial to split both tasks. For example:\n* Baking an animated geometry and the loading it at different frames for re-timing.\n* Load multiple baked frames of the same Bake within the same frame.\n* Baking a geometry in one .blend file and then loading it as a cache in another.\n\nAll of these use-cases turn our baking format into a more general purpose interchange format like Alembic that is Blender specific. Baking into other formats will be possible eventually as well, but it not part of this project. Using a custom format allows us to optimize it for our needs and avoids the problem that Blenders data does not always map 1 to 1 to how data is stored in common formats. Also see [this](105251) task.\n\nThe import can be done with a new Import Bake node which takes a (file) path and a frame as input and outputs the geometry. There are some problems that need to be overcome:\n* The Import Bake node ideally has the same sockets as the corresponding Bake node, but this can't be guaranteed when they are in separate .blend files.\n* While not supported yet, it will be possible to pack baked data into the .blend file. Therefore, the path input is sometimes a path on disk and sometimes some internal identifier.\n* It should be possible to use the combination of a Bake node with one or more Import Bake nodes within a node group without having to hard code the file path for all of these nodes. Therefore, it seems reasonable that the Bake node also outputs where the baked data is stored. Also see [this](29266) older proposal.\n\n## Milestone 4: Editing Baked Data\n\nThe idea is that the user can just go into edit, sculpt or other modes on the baked data and edit it in place. For animated geometries, every frame can be destructively edited separately. The goal here is not to record all manual edits the user did. After baking again, the edits will generally be gone.\n\nWhile this might seem like a small feature, if done right, it can have huge impacts on the way people work with geometry in Blender in the long-term. That is because it could theoretically allow us to get rid of the idea of \"original geometry\" in Blender (e.g. the mesh referenced by `object->data`). To give a glimpse into what could become possible: Adding a cube object could just add an \"empty\" object with Cube node in geometry nodes. This allows the primitive mesh to remain procedural. Going into edit mode could implicitly (or explicitly) add a Bake node and bake the cube so that it can be edited destructively.\n\nAs for this milestone, the target use cases are more minor and mostly revolve around fixing up \"bad\" data in animated geometry. For example, in a particle simulation, a single particle got too close to the camera and blocks the entire view. It should be possible to just delete it manually. \n\n## Parallel Track 1: UI for Unused Nodes\n\nThere are various situations in which nodes in a node group are unused:\n* Nodes not connected to the output.\n* Nodes that would compute the unused input of a Switch node.\n* Nodes that were used to compute a simulation that is now cached.\n* Nodes that compute the inputs to the Bake node which is now baked.\n\nCurrently, there is no obvious way for the user to determine which nodes have been evaluated by the last evaluation. However, this information would be very useful because it allows seeing at a glance when data is cached/baked.\n\nLogging the set of nodes that has been evaluated is relatively [straight forward](107780). However, we still need the a good UI for these nodes. The obvious solution is to just gray out these nodes. While that can work, it's not ideal because the nodes can and should still be editable and graying out usually indicates that the user is not expected to edit them.\n\n## Parallel Track 2: Store Baked Data in .blend File\n\nWe already support packing external files into .blend files. That system just needs to be enhanced to also support baking entire folders full with baked data. Ideally, it is possible to load the baked data lazily when loading a .blend file, but that's probably quite a bit more challenging. It remains to be seen how much of a performance hit loading all frames at once has.\n\n", "Search of nodes from multiple strings\nFor the math nodes it would be good to have a way to search \"dot\" and add the attribute vector math in the \"dot\" mode.", "Mitigate the risk of wrong shape key selection in sculpt and edit mode.\n# The Issue\n\nA major weakness of any layered editing system is that it matters which layer is selected for editing operations, but this selection is not apparent in the actual editing space, because layer effects are by definition combined into a single result for display.\n\nFor instance, unless the single key mode is turned on, the effects of all relative shape keys are summed up into a final shape, which doesn't change no matter which one is selected.\n\nThis means that it is easy to apply editing operations to the wrong selected layer, including a possibility that the undo stack will be exhausted before the mistake is noticed.\n\nAn additional risk factor is that shape influence sliders are located in the same list, and a hurried misclick on a slider can change selection.\n\n# Proposed Solution\n\nThe industry standard way to mitigate this risk is layer locking: layers that are not currently being worked on can be locked by the user, in which case all editing operations that would affect that layer will instead abort with an error.\n\nBlender already supports this with Vertex Groups and weight painting - even though with groups it is more obvious which one is selected, and locking has additional effects related to normalization.\n\nI propose adding this feature for shape keys (implemented in #104463):\n\n\n\nSince it is a standard approach that is used by any advanced image editor, most users would likely be already familiar with the concept. However there are some details in its application that need discussing.\n\n## Scope Issue\n\nThe primary design question is which operations should react to layers being locked, balancing mainly implementation complexity and the effectiveness and convenience of the feature.\n\nIn implementing the prototype I decided that the main criteria should be:\n\n* Operations that affect vertex positions, and thus shape keys.\n\n* Operations where the shape key selection matters:\n\n For example, applying object mode transformation updates all shape keys. Thus the selection doesn't really matter, and respecting locks would inconvenience the user that is working on the scene layout, rather than individual object details.\n\n* Deform-only operations:\n\n Even though selection may affect the final vertex positions, operations that change topology necessarily change all shape keys. For that reason, topology manipulation also belongs in an earlier stage of the design pipeline than shape key creation, even though it may be necessary to do it later sometimes for various reasons. Finally, topology change is seldom not accompanied by using transformation operators that respect the locks.\n\n### Current Scope\n\nThis is the current scope of the checks in the prototype:\n\n* All Edit Mode <u>transformation</u> operations.\n\n Specifically, everything invoking the generic transform system initialization code.\n\n* All <u>Sculpt brushes</u> that affect vertices, and not colors or masks.\n\n Specifically, everything invoking the generic brush stroke initialization code.\n\n* <u>Smooth</u> and <u>Laplacian Smooth</u> operators in Edit Mode.\n* <u>Blend From Shape</u> operator in Edit Mode.\n* <u>Propagate To All Shapes</u> operator in Edit Mode.\n\n This one is a bit of a problem, because technically shape selection doesn't matter here: it snaps all shape keys to the current position. However currently I implemented a check to abort if any shape key is locked on the principle that it is a shape key operation. Maybe it should only check the main Basis, or work in some other way.\n\n* <u>Mirror Shape</u> and deleting shape keys.\n\n* A few other operators...\n\nThis [spreadsheet](edit?usp=sharing) containts an exact listing of which operators should and actually do check for locks.\n\n# Discussion\n\nIt is necessary to discuss whether the main criteria, or this specific list needs changing. For instance, I'm not confident that I remembered all operations that match the criteria for the checks.\n\nAnother minor design point is whether attempting to edit a locked layer should be an error (shows a message under the cursor) or a warning (appears in the status line).\n\nSince the checks are done by operators rather than low-level code, add-ons would have to implement them too where relevant. I wonder how many would be affected, and whether some API additions to help them do that easily would be necessary.\n\nThere have also been some questions raised in #104463, like:\n\n> - Are shape keys a special case? (is there other data we might want to lock).\n> - Is the current implementation disallowing editing in all anticipated situations? There seems to be quite a few ways to transform vertices that aren't included here, applying transform, moving object origins, ... to name a couple, probably other mesh tools too. It may feel like an incomplete feature if these are left out, yet, this means we need to add check in many more places.\n> - Are there ways this can be implemented in a way that doesn't frustrate users. For example, you load someone elses file, select objects and want to apply transform. If they have locked a shepe-key it could mean having to manually select and disable the the locks. Users may request a ways to disable locks on all selected objects, maybe going along in this direction is fine, but we can anticipate some of these issues and consider functionality that doesn't add unnecessary overhead. \n", "Delete geometry node performance regression writing to multiple vertex groups in 3.1\nOperating system: Windows-10-10.0.19042-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.84\n\nBroken: version: 3.1.0\nWorked: 3.0.1 and older\n\nCaused by f5e5a0987a\n\nUsing a combination of Delete Geometry node along side the Armature modifier makes the node run slower and slower the more vertex groups armature is using.

The main reason is that those separate IDs which are not serialized as part of simulation baking. Ideally, baking materials would just work, at least in the most common circumstances.\n\nWhile this task is about materials, the same thoughts also apply to other referenced IDs like object/collection instances.\n\nThere are two main possible solutions:\n1. Serialize materials as part of the simulation state.\n2. Only store a reference to the material in the simulation state.\n\n### 1. Serializing Materials\n\nSerializing materials has the benefit that it could just work. We'd have to store all the materials for every geometry in the simulation state in cached frame. Though, it's possible to deduplicate this to some degree of course. Serializing materials would also involve serializing the node graph and potentially even more referenced data like images. At some point we most likely want things to stay referenced, so the problem is just moved to a different place. Another problem is that the materials are essentially recreated on every frame. Blender does not really have the ability to work with materials that are not in `Main` currently.\n\n### 2. Storing References\n\nStoring a reference to the material mainly means storing a material name and an optional library name in the simulation state. Then, when loading the simulation state, the materials available in the .blend file are mapped to the loaded geometry. Conceptually, this is also very straight forward. Materials can still be edited like they always have been. A potential problem is that if materials are renamed or removed, they can not be linked correctly anymore. However, that is somewhat expected with linking already. While this approach is easy design wise, there are some technical difficulties: The main problem is that we only know which materials are used by the baked data, once the data is loaded. And, to make matters more difficult, we might only know which baked data to load once depsgraph evaluation has started. That can happen when e.g. the file path to the data on disk is dynamically build/choosen during evaluation (this is not supported right now, but likely will be at some point).\n\nThe problem with knowing which materials will be used by the geometry is that materials are part of the dependency graph. As such, all materials we wish to use for rendering have to be added to the dependency graph *before* evaluation starts. As of right now, it's not possible to lazily add materials to the depsgraph once it becomes known that it is required.\n\nThere are a couple different possible solutions with different trade-offs:\n* A. Always add all materials to the depsgraph. This would be a simple solution, but it's obviously not scalable. Even less so if we wish to use the same solution for other kinds of referenced data like objects.\n* B. Only support linking baked data with materials that are referenced by material slots on the object or original geometry. This means that if the simulation state happens to contain materials used by e.g. other imported objects, those will not be linked correctly.\n* C. Detect all materials \"reachable\" from an object and always add those to the depsgraph. This might have noticeable overhead when potentially large parts of `Main` have to by scanned by many objects. It also wouldn't work in all cases. For example, if the simulation has been baked, and then the .blend file changes in ways that the material is not reachable from the object anymore. Then the material would not be linked correctly.\n* D. Store a name-to-material mapping on the modifier. This mapping could be created/updated automatically when baking or at other points in time. Only materials in this mapping can be linked when loading simulation state. If the simulation state contains a material name that is not in the list, we could show a warning and automatically add it to the list with the press of a button in many cases. With this approach, the user also has the ability to replace a material after baking easily. The mapping could also have per simulation zone overrides for more control.\n\n-----\n\nCurrently, my preferred solution is referencing the materials by name in the simulation state and use option D to do the linking at evaluation time.\n\n", "Geometry Nodes: Going back to frame before simulation cache returns no geometry if frame is out of scene frame range\nOperating system: Linux-5.17.15-76051715-generic-x86_64-with-glibc2.35 64 Bits, X11 UI\nGraphics card: Quadro RTX 6000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 515.48.07\n\nBroken: version: 4.0.0 Alpha\n\nOut of scene frame range:\n\n\nInside scene frame range:\n\n\n- Add geonodes modifier\n- add simulation zone\n- run simulation to build up the cache\n- Go to frame 0\n\n", "Geometry nodes material index attribute not working correctly on generated/instanced geometry\nOperating system: Linux-5.8.0-7630-generic-x86_64-with-glibc2.32 64 Bits\nGraphics card: Quadro RTX 6000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.32.03\n\nBroken: version: 2.93.0 Alpha\nFYI, the history on this:\nprior to 1a81d268a1 this was working in editmode (but not objectmode)\nafter 1a81d268a1 no material was shown in the viewport at all\nthen with 6583fb67c6 we had first material showing again, but setting index was not working in either objectmode nor editmode\n\nchanging the material_index attribute does not seem to have an effect on created/instanced data, even though the material index seems to change accurately in the spreadsheet and the material slots are set to `Object` type.

But from the time I remove the image block its contents will always be zero even if I redo the rendering.\n\nThe only way I could successfully update the contents of the image block was after, first, I followed *Sebastian Koch*'s solution and then wrote some code to remove/add all nodes and their links to get either depth map or surface Normals and did the rendering again. But the whole point of me trying to store pixels into Numpy arrays was to avoid doing re-rendering to get around the IO overhead. I could have instead stored two files (for both depth map and Normal maps) throught two Output nodes with rendering only once.\n\nFirst, if this behavior does not look like a bug, I would appreciate the community provide me an easy solution to do what I want. Second, It would be great if you can improve Blender's Python API and add ways of easily accessing rendering results in memory so that people like me who want to do millions of rendering do not need to deal with the delays cause by IO to transfer rendering results from memory to hard drive and can easily store the results into Numpy arrays and store them on disk in chunks. \n\n", "Geometry Node: Input Color node: Custom color and value color is the same property\nOperating system: Linux-5.15.0-60-generic-x86_64-with-glibc2.31 64 Bits\nGraphics card: NVIDIA GeForce GTX 1060 3GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 515.86.01\n\nBroken: version: 3.4.1\nWorked: Never.\n\n\nCustom color and value color is the same property.

That is, within a single Grease Pencil object and you have strokes in front of and behind a solid object, you can see the strokes behind the object through the strokes in front of the object even though the object is completely opaque. This is problematic because I am trying to animate some linework on all sides of a surface of a 3D object.\n\nI am attaching a .blend file here that illustrates the problem. Later I'll describe how I created this file.\n[TransparentGreasePenci.blend](TransparentGreasePenci.blend)\n\nTo observe the problem:\n\n - Open the .blend file\n - Observe a sphere and 2 grease pencil objects (one has blue strokes and the other has red strokes)\n - Rotate around the scene\n - Observe that through any of the blue strokes in front of the sphere you can see artifacts of the blue strokes that should be hidden behind the sphere. You cannot see any of the red strokes from the other GP object behind the sphere.\n # Observe that through the red strokes in front of the sphere you can see artifacts of the red strokes that should be hidden behind the sphere.\n\nI don't know if this behavior is expected or not. While it could be a cool effect, it completely defeats the workflow I was trying to achieve or it will force me to split my Grease Pencil strokes among multiple GP objects. If I had to guess, it looks like the GP objects are rendered to a separate buffer and merged, which means they only get a single Z value to compare with other 3D geometry. Of course, I haven't looked at the code yet.\n\nHow I created the example:\n\n - Create a sphere\n - Create an empty Grease Pencil object\n - Change the material color to blue\n - Change the Stroke Placement to Surface\n - Add a mirror modifier\n - Draw strokes on all sides of the sphere\n - Observe the problem described above\n - Create another empty Grease Pencil Object\n - Change the material color to red\n - Change the Stroke Placement to Surface\n - Draw strokes on the front and back of the sphere\n - Observe the stroke visibility issue described above\n\n", "Grease Pencil Xray strokes appear as mask\nOperating system: Win 10 x64\nGraphics card: NVIDIA Geforce 1060 GTX\n\nBroken: blender 2.80, 1ae6aaad43ad, 2019-03-22\n\n\nrendering glitch when Grease Pencil lines are hidden because of Xray but also appear because of 2D ordering\n\n\n\n\n\n\nWith surface projection, draw lines on a GP layer set as 2D depth order on both side of a mesh.\n\nWith the right angle selected, the hidden lines (because of the Xray deactivated and the mesh being in the way) actually cut the lines that should be visible.

If you scale your model with a negative\nvalue in editmode, you get flipped normals. This is because the vertex order in the\nfaces is preserved and that is what determines the normal. In object mode however,\nthere is a flag in the render engines to flip the normals back, if they are flipped due\nto negative scale. This inconsistency creates the problem with the apply transforms\noperator. The following image shows on top the behavior in editmode and at the\nbottom the behavior in object mode.\n\n\n\nOf course both behaviors have their reasoning to exist.\n\nOne reason for the rendering flag to exist is, that instances of the same object can\nbe mirrored without causing normal problems. Obviously there is no other solution\nto that, since the underlying mesh is the same for all instances, so the render engine\nhas to handle negative scales.\n\nOn the other hand, in editmode you don't want to change the loop order for all your faces\nif you are just scaling. It makes much more sense for editmode scaling to just change\nvertex coordinates. That means you need to fix the normals manually.\n\n\nThe apply operator can only be called in object mode. From object mode the current\nbehaviour looks as if it was flipping the normals. Actually it is just applying the\ntransform \"in editmode\", which looses the negative scale information for rendering.\nThis looks like a bug to some users and is confusing for new users. Users have actually\nrequested this to be changed:\n\n4Zdbbc/\n\nI also heard this request on the BCON22.\n\nHowever the question arises, do we add another option or do we just always flip the\nnormals to make it consistent with rendering? Another question is what happens to\naddons which are using this operator if the operator gets changed in this way?\nHow many addons are actually using apply scale on negatively scaled objects?\nDo those addons fix the normals by flipping them manually?\n\nThere is already a patch available to add this normal flipping without an option:\n\nD16382", "Transform generalized custom-data correction support\n\n**Motivation:**\n\nHaving to manually adjust custom-data is tedious\nwhile there is a UV correction option,\nit's limited to vertex & slide.\n\nThis proposal is to generalize the option so it can be used for any\ntransform mode.\n\n\n**Solution:**\n\nThis proposes to add two kinds of custom-data correction methods.\n\n- Correct based on surrounding geometry, this is suitable for\n```\nvertex & edge slide.\n```\n *The existing logic for vertex & edge slide can be used here.*\n\n- Project Custom-Data\n\n```\nThis would project geometry onto the surfaces of the original mesh\nto calculate the custom-data.\nThis would allow geometry.\n```\n\n```\nThis could be used for other transform modes besides vertex/edge slide.\n```\n\n\n**Limitations:**\n\nThis option works best when adjusting small regions of geometry and often won't work well moving large regions of faces.\n\nThere is a limit to how much UV's can be corrected in this case without re-unwrapping/projecting\n*(which is beyond the scope of this proposal).*\n\n\n**User Interface:**\n\nThese would be shown in the tool options panel, we could keep the transform option too (although this isn't essential).\n\n----\n\nThere is a risk that users accidentally leave this enabled and transform their UV's when moving the geometry.\n\nSince we have other fairly obscure options (transform origins for example), it may be best to show these are enabled while transforming (as we do for auto-keyframe).\n", "Incorrect combined texture baking with subsurface material\nOperating system: windows 10\nGraphics card: gtx 1070\n\nBroken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen)\nWorked: (optional)\n\nBaking result is different from what I have seen in render and has strange artifacts.\n\n\nOpen attached file and run combined baking with default settings.\n[test_bake_2_79.blend](test_bake_2_79.blend)", "Alpha channel of Textures can't be deactivated in UV Editor\nOperating system: Windows10\nGraphics card:Geforce GTX 970M\n\nBroken: 2.91.0\nWorked: 2.83.0\n\nWhen you load an Image/Texture with an alpha channel in the UV editor, you can't turn the alpha channel off anymore, the image will stay black.\nIt worked in older Versions from 2.80 up to 2.83, there you only have to click on **Color** in **Display Channel** options.\n\nOnly areas that aren't black in the Alphachannel will be visible, in my examples I work with textures that need an all black Alpha channel.\n\njust load any Texture with Alpha channel in UV editor viewport\n\n\n\nHere an Screenshot from Blender 2.83.0 where it worked\n\n\n\n\nand here an screenshot of Blender 2.91.0, the same Texture is used, I also tried different settings under Image, but nothing works\n\n\n", "Shader nodes.

The modifier would remain, but would likely be used less.\n\nThere are a few reasons for this:\n* OpenSubdiv GPU acceleration in the viewport and adaptive subdivision in Cycles need the modifier to be last in the stack. The available settings, behavior and implementation would be more clear if this was controlled outside of the modifier stack.\n* When we add modifier nodes support, the concept of a last modifier in the stack becomes fuzzy. Being able to pass along a subdivision surface Mesh to another node without actually subdividing is important for performance and to leave subdivision to the renderer.\n* For best performance with GPU acceleration, we don't want Blender to also subdivide the mesh on the CPU at all. But operations like hair positioning, particle emission and snapping still need to take into account the subdivision surface. If the Mesh datablock contains all the subdivision surface information, these could potentially work on the limit surface without subdividing the mesh on the CPU.\n* Simpler smooth normals handling, see #68893 (Smooth shading usabilty).\n* File formats like USD have native subdivision surface primitives.

While the file is being written, Blender's UI is gray and unresponsive.\n\nThe problem is not pressing, as usually it takes considerably longer to load the files in the first place. I've asked some artists at the Blender Studio and they didn't really consider the delay when quitting Blender a practical issue. Still, it gets somewhat in the way of quickly testing things with various production blend files, so it could be seen as an issue for developers more than for artists.\n\n### Possible Solutions & Impact\n\n**Simplest solution:**\n\nAs a solution we could introduce a user preference \"Save Recovery File\" that is enabled by default. Disabling this option would:\n- Avoid writing `quit.blend`.\n- Remove the \"File ‣ Recover ‣ Last Session\" menu item.\n- Remove the \"Recover Last Session\" button from the splash screen.\n\n**Alternative solution:**\n\nThe \"Recover Last Session\" operator does not poll the filesystem from its poll function. This means that the operator is available even when the file `${TEMPDIR}/quit.blend` does not exist. Changing this, such that the operator is disabled when `quit.blend` does not exists, means that the above solution would not have to remove the recovery operators when \"Save Recovery File\" is disabled. The operators would auto-detect whether a recovery file is available at all.\n\nThe upside of this solution is that it makes the \"Recover Last Session\" operator appear more reliable, as it refuses to work when it knows it cannot do its job. This would be an improvement regardless of the \"Save Recovery File\" status.\n\nThe downside is that an old `quit.blend` might be lingering around after \"Save Recovery File\" has been disabled. This means that it could appear as if you could still recover, but it would load an older file. This could be avoided by removing `quit.blend` when disabling \"Save Recovery File\", but I'm not a big fan of Blender explicitly removing files that are meant to recover from human error.\n\n### Discussion Topics\n\nThis task is meant to discuss the following:\n\n- Do we want to make it possible to quit without writing `quit.blend` at all?\n- If so, which of the solutions is preferred? Or is there another way to deal with this that's even better?\n- Do we want this as a general option, or something that's enabled only when \"Developer Extras\" are enabled?\n", "Python Operator.report does not show in status bar when overriding context\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 2080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 497.09\n\nBroken: version: 3.2.0 Alpha\nAlso broken all the way back to 2.79.\n\nAn operator's `report()` call does not show a message in the status bar or info editor when the operator is not invoked by the user.

I compare it to the Curve Deform modifier as an example of proper deformation. Now, you may say it's an unfair comparison given that curves have an explicit twist that you can modify, unlike hairs. But even without controlling the initial twist of the hair, it's broken in a couple of ways.\n\nFirst, it deforms the mesh unevenly, with some vertices twisting more than others, even in a case where vertices are completely equidistant around the origin and both origins are aligned, like the cube in this image. The selected face and the edgeloop here should be squares but aren't, unlike in the curve deform modifier \nSecond, when changing the length with the Position Slider, the whole thing seems to change twist at once. Instead of having a consistent twist on each point of the path [Particle Instance Mod bug2.mp4](Particle_Instance_Mod_bug2.mp4)\nAs a side note, when using Along Path, finding how to orient your mesh to the hair is unintuitive, always using the global Y axis as the length axis in which I added subdivisions but then twisting weirdly when changing the Axis option in the modifier, I settled for Z in this example.\n\n\nAttached is the same file used in the video, you can open it and move the Position slider in the Particle Instance Modifier, the scale of the Curve Deform modifier example is driven by it so you can see both changing in real time.\n\n[ParticleInstanceTwistBug.blend](ParticleInstanceTwistBug.blend)\n\nWhy do I think this is happening? Well, if you select the object with the particle system, go to the particle properties, and change the length of the hair under the Render>Timing>End subpanel, you can see the problem is the same, basically the twist changes with length. Maybe the modifier should do something different and get the twist from the whole length particle and then scale the mesh instance before deforming or something like that, idk\n\n", "Simulation issues with new hair object converted to legacy particle hair\nOperating system: Windows-10-10.0.22000-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.94\n\nBroken: version: 3.3.1\n\nSimulation of particle hair system (legacy) which was converted from new hair object has issues.

It seems that it really depends on where the vertices line up. I've been cutting window slots out of ridged galvanized steel plates using boolean cubes and it's worked for every other object. However, this one particular piece in my scene has been causing endless trouble for me despite being the exact same procedure. Seems as though I need to put my boolean objects in the EXACT RIGHT place for them to work right. I found that adding a ludicrous number of subdivisions w/ the subsurface modifier can somewhat help, but it greatly depends on whether or not I position my cubes in the right spot. It is preventing me from placing my windows where they need to go on my scale accurate historic building recreation. I don't know why this object is being so temperamental but it is blocking me from making any progress on this side of the building and I'm afraid I'll keep running into the problem later on.\n\nI may post additional demo files that showcase more boolean issues as I frequently run into problems of faces not being filled properly, crappy vertex extrusions, objects being weirdly combined instead of differenced, and many more annoyances. I hope booleans can get a lot more love from the developers so that they work as intended.\n\n\n\nI'm not entirely sure how to reproduce an issue like this. It mostly plagues more detailed models but can happen anywhere and depends on object positions, alignment, topology, and so on. Attached is a problematic file.\n\n**Attached file information**\n[F12870489](brokenBooleans.blend.zip) There are several issues present. For one thing, the boolean modifier is struggling to cut a simple rectangle out of a plane. It is adding geometry to certain parts, cutting out geometry that shouldn't be cut out, and is not accurate at all. I've noticed that using the \"fast\" option usually yields better results than using the \"exact\" option. However, in the case of this object, it actually breaks it EVEN MORE! Try selecting the \"cutoutGalvanizedSteel\" (planar object) and setting the booleans to \"fast\" to see a new problem emerge. Adding a solidify modifier to the very top of the stack will fix the issue. However, booleans should work on planes, too.\n\n[F12871474](BorkedBooleans.blend.zip) Many different problems. Boolean objects are displayed as wireframes. If you see a boolean as having geometry, it's because it is being added by the Boolean modifier. The boolean modifier likes to add the boolean's geometry to the source mesh sometimes, even when it is set to difference or intersection. In issue 2, there is a mesh problem in the boolean. If you enter edit mode, you can see that the problematic vertices are selected. They crash the boolean operation altogether. Merging these vertices will solve the issue, but for more complex boolean objects, this may not always be an option.\n\n[brokenBooleans.blend.zip](brokenBooleans.blend.zip)\n[BorkedBooleans.blend.zip](BorkedBooleans.blend.zip)", "Improve UX for interaction of modifier stack and node editor\nWhen a non-nodes modifier is selected as active modifier there is no indication or way to change that in the geometry nodes editor and it's very confusing for the user, especially when the properties editor is not displaying the modifiers panel.\n\nThis is related to #84927\nA potential solution has been proposed there as well (move towards interface similar to shader editor and material slots).", "Curves don't have 'All Edges' option for wireframe\nBroken: 2.80\n\nMesh objects have the toggle for its viewport display wireframe to render all edges, but curve objects don't.\n\n\nOpen the attached file and look for the 'All Edges' option.\n[Wiref.blend](Wiref.blend)\n", "Shader nodes.

[ "Collada: Todos\n## OpenCollada\n\nMoving opencollada bugs to TODO has been done since this has so far not yet been effectively maintained.\n\nThis is not a step to remove collada support, however if in the next year there is little work done in this area we may have to reconsider.\n\n----\nI propose the first goal to get blender exporting armatures, animation & geometry to 1 application successfully as a first goal.\n\nSince the 2.4x python script was capable of this, it should not be so hard.\n\nExport to SecondLife can be our first target, this has the advantage that secondlife is opensource therefor easier to get hold of for testing.\n\n### Plans\n\n**Short term goals (Blender 2.64)**\n\n- [ ] Make export and Import more robust. Idealy reimport of an exported collada file should recreate the original data.\n- [ ] Organize module testing. Please feel free to provide test cases and results on the Export page (dead link)\n\n**Long term goals**\n\n- [ ] Investigate in ways to improve the Collada module. Currently 3 possible approaches are investigated:\n - [ ] Fix the current Bugs and make the OpenCollada based module stable and fit for purpose\n - [ ] Refactor/Rewrite the module based on OpenCollada\n - [ ] Create a Python based solution.

Notes: |\n| -- |\n| - This is a direct dump of Scripting (without cherrypicking the [still] valid items)\n| - Changed the broken python documentation links |\n\n\n**Unstable or poorly tested**\n- [ ] BMesh operators currently use int's for enums that have undocumented values. blender/blender-addons#34914\n\nFixes that still need doing.\n**Internal API Problems**\n- [ ] Class registration needs to be reworked. as well as some internal bugs fixed.\n- [ ] RNA api has a bug where 'raw_type' defaults to INT but is not set for MFace verts in makesrna.\n- [ ] ID data returned from functions is not included unless the type is an ID itself.Returning a mesh will work but not a meshes face for eg. See bpy_rna.c - /- [ ] XXX this is missing the ID part! []/\n- [ ] Dynamic enums currently refer to invalid memory when accessed from python, we need a way for python to hold the memory until its done with the dynamic enum.\n\n**Low Priority Py API**\n- [ ] Re-Registering classes leaks memory, would be good to resolve this. (see comments in bpy_rna.c)\n- [ ] 'Safe Mode' - where writes to invalid memory are detected.\n- [ ] Implement import hooks rather than replacing import/reload pep-0302/\n\n### Python/RNA API Design TODO\n- [ ] Add a way to cancel running scripts from the user interface, with no console this becomes very problematic (Esc --> KeyboardInterrupt for example).\n- [ ] Currently there is no way to write packed images from blend files, support for this should be added to exporters. eg: image.pack_write(\"somepath.png\")\n- [ ] Addressing operators/panels/menus, should we translate all names fromSOME_MT_menu --> some.menu, ONE_PT_panel --> one.panel ? would mean the UI code could reference them by this more pythonic syntax.\n- [ ] need to decide how 2.4x api's will fit in with new apis. PyNodes, PyConstraints.\n- [ ] convenience function to get selected verts/edges/faces to prevent expensive iteration over meshes. Something like: me.verts.selected\n- [ ] Design a method to allow custom UIs to filter properties/options. Useful for Blender GE too (example: which constraints are supported (#26804). Complex matter for which rna needs to be extended?\n- [ ] Zero bytes are not supported in RNA byte string types, see blender/blender-addons#32581\n- [ ] Better python API and undo stack integration, see #38386\n\n**Inconsistencies**\n- [ ] bpy.ops.mode_set(...) has different mode-names than bpy.context.mode. E.g. TEXTURE_PAINT vs PAINT_TEXTURE''CoDEmanX:'' Getting mode from bpy.context.mode for mode_set() is inappropriate, use '''bpy.context.object.mode''' instead!\n- [ ] bpy.ops.object.move_to_layer() takes a boolean array of 20 elements (like in Blender GUI), but most functions require 32 elements. bpy.ops.object.add() for example.\n- [ ] bone.matrix returns a matrix, but requires a list when assigning to it. This also goes for some of the other matrix attributes of bone, editbone and posebone. [appears to be resolved as of 2.67?]\n- [ ] the term 'size' is used incorrectly in some cases, where it should be 'scale' instead. Review and correct: search.html?q=size&check_keywords=yes&area=default\n- [ ] keyframe_insert(), options for insert or replacing existing keyframes, threshold for detecting doubles see: bpy.types.bpy_struct.html#bpy.types.bpy_struct.keyframe_insert\n- [ ] The ID data block path returned by RNA_path_full_ID_py (rna_access.c) for node trees only works for node groups, which are stored as true ID data blocks in bpy.data.node_groups. For material/compo/texture nodes which are part of Material/Scene/Texture respectively the function can not determine the correct path. Best solution would be to get rid of nested ID data blocks altogether blender/blender-addons#35720\n\n### Python RNA access\n- [ ] Remove mesh vertices / edges / polygons (without bmesh module)\n- [ ] Shorthand for active vertex / active edge (bmesh module)\n- [ ] Active vertex / edge index for meshes (like Mesh.polygons.active)\n- [ ] Remove Shape Key\n- [ ] Remove Curve Points\n- [ ] Particle edit mode\n- [ ] Start/stop the physics sim\n- [ ] Sculpt mask custom data\n- [ ] Add / remove rigid body + constraints + world\n- [ ] Add / remove transform orientation\n- [ ] Add / remove Text curve object Textboxes\n- [ ] Add / remove Particle Systems\n- [ ] Sequencer, ability to load and images blender/blender-addons#40663\n- [ ] Pixels and resolution are not available with multilayer EXR or Render Result images #53768\n\n### Python Console\n- [ ] Append to (and remove from?) SpaceConsole .history and .scrollback\n- [ ] input() is not supported #40592\n\n### General todo items\n- [ ] Operator redo (toolbar) could also change the last InfoWindow print of the python operator equivalent.\n- [ ] mathutil.geometry.intersect_point_quad_2d works inpredictable for non-concave or quads with singularity edges #30831\n- [ ] modules/rna_xml.py: BoolVectorProperty and CollectionProperty issue blender/blender-addons#32882\n- [ ] Drivers should be able to access '''self''' for bones and objects.\n- [ ] Add the ability to report() without an operator, internally use

that there is an access violation when reading at position `0xFFFFFFFFFFFFFFFF`. `node->typeinfo` does exist (is not null), but `freefunc` (and actually most of the other attributes) point to `0xdddd...`. Because of that, I think that this bug might be caused by a similar issue as described in #72833.\n\nI'm not sure if a core dump helps you, it's quite large (1GB + another GB for the .pdb file) so if you need it I can look for a way to make it available to you. I'm not a C or C++ dev so I don't know what is helpful.\n\n**EDIT**: I think this crash is caused by opening files files with nodes that were registered while the file was originaly saved but not anymore.\n\nIt's a bit complicated because it doesn't happen all the time. The particular file(s) where I observed this issue use nodes from an addon (Armory3D) which supports per-project custom nodes which get registered via a `on_load_post()` handler (so there is a delay between opening the file and registering the nodes). I'm not entirely sure, but it seems like the crash occurs when the nodes are registered again. The crash even occurs when unregistering the nodes before saving the file.\n\nBecause of that complicated setup (addon required + project setup + custom node package) I will go without an example file. If you aren't able to find the cause without one, please tell me so that I can prepare a minimal project setup for you.\n\nThank you very much!\n\n*Original issue*: 1890", "Show warning when saving a .blend file with that has been saved with a newer version before\nThe following scenario is a big difficult with our versioning code:\n1.

For example, when using the `index` output of the `Particle Info Node` to compute a texture coordinate for each particle used to compute individual colors for the particles produced strange results.\n\nHere a working example for 120 x 120 particles (as reference)\n\n\n\nAnd here a non-working example for 200 x 200 particles (zoomed on the bottom-right corner)\n\n\n\nSide note: In all the examples, the particles are there, but the instance object representation is missing.\n\n\nExecute the following Python script within Blender's text editor.

The property should be lockable by the user in order to fix any unwanted scaling on a specific axis.\n\nAnother solution is to add properties that is a factor (multiplier) to the scaling/stretching per axis.

Pressing undo once will only remove the last Grab brushstroke as expected but also revert the active brush to the Draw brush which is not expected.\n\nAfter loading factory settings, the problem doesn't exist. What causes it to happen is if you add an additional New Main Window and set it to the UV Editing workspace and combine the UV Editor area and the 3D Viewport area to make just one large UV Editor area.

The idea here is to ask the question “if Multires was working exactly as intended (no bugs, no TODOs, all possible optimizations...), is that what we want for the sculpting/painting modes?”\n\n## Pros\n\n- **Tangent space sculpting layers**: This is a feature that even specialized software doesn’t support and which is really important for retouching VFX animation. By having multiple ##CD_MDISP## datalayer, it should be possible to tweak the influence of each one of them on the final displacement. As these layers are in tangent space, this supports any transformation on the base mesh without applying the layers displacement in random directions. \n\n- **Supports features that require base + displacement**: Features like displacement eraser or displacement smear rely on having the sculpt geometry stored as a base and a displacement. The current Multires design makes supporting these features straightforward. When Multires is not being used, it is still possible to implement these brushes by creating an operator that generates a base (by smoothing the mesh multiple times) and a displacement. So, this is not a feature that relies on the design of Multires, but it makes it better integrated.\n\n- **Sculpting and rendering different levels**: It is possible to use sculpt mode to deform the limit surface and let the modifier evaluate the displacement of other level. With a delete lower operator and unsubdivide, it should be possible to create a temporally base mesh for any level so it can be sculpted as a limit surface.\n\n- **Easy to integrate with rigs**: For the rest of the animation system, multires is just like having a vector displacement texture on top of a model. Animating models with sculpted displacement does not require any further workflow or features from other modules. \n\n- **Saves a lot of memory**: As it does not store any topology information for the higher levels of the sculpt, it is memory efficient both when sculpt mode is in use and when saving the files.\n\n- **Faster PBVH building times**: as the BVH primitives are the grids, building the tree is faster than building it for the individual triangles of a mesh.\n\n\n\n## Cons\n\n- **No references or indices for edges and loops**: Mesh algorithms that require storing information or topology queries based on edges can’t be implemented. This means like features like fairing, geodesic distances or a better cloth solver can’t be directly available from the ##SculptSession## (I still don’t understand why the current cloth solver works, but its performance is really bad). In order to have those features working, I can only think of workarounds like converting the grids to a mesh or adding some kind of map to store the grids topology as edges and vertex references, which adds extra code that needs to be maintained and misses the point of using grids directly to save memory.\n\n- **Computed and displayed resolution does not match**: When working on level 1 of a quad mesh, all vertices will have 4 duplicates which will be deformed independently when computing the brushes and tools. For the user, this means that performance and vertex count won’t match the sculpt mesh that is being rendered. This makes Multires usually slower on level 1 than on level 5. It also creates unexpected results when adding a single subdivision to a mid/high poly mesh, as the vertex count will increase at a rate users won’t expect.\n\n- **Allows vertices with invalid data state**: This design allows to have a vertex with multiple mask, colors or visibility values. This can be solved with stitching the grids, but this should be something that the design should not allow. It is the cause of constant bugs in all tools that require storing data per vertex. (see #79317)\n\n- **Performance depending on grids dimensions**: In lower levels (on a 2x2 grid), the number of duplicates exposed to the tools is so high that creates performance problems. When the grids are too big, performance decreases because the tool iterations are per grid. This causes that multires optimal performance is only achieved in levels around 5. This is something that users don’t expect. For example, subdividing 4 vert plane 8 times will create a reasonable vertex count for sculpting, but because grids at level 8 are so big, sculpt mode will always update at least a quarter of the plane regardless of the size of the brush.\n\n- **PBVH limited to building per grid**: In order to get the PBVH building speed, grids are used as primitives. This means that the number of nodes can’t never be higher than the number of grids. On higher multires levels, this is a problem as the PBVH can’t have as many nodes as it should for optimal performance. \n\n- **Undefined behavior with undo and shape keys**: The relation between shape keys in the base mesh, sculpt layers and multiple ##CD_MDISP## layers is not clear. We don´t know if shape keys should also contain the info about the displacement of the grids, if they should only deform the base mesh or both. What undo should do with features like propagation and reshaping from sculpt mode is also not clear. \n\n- **Incompatible design with automatic apply base**: With the current Multires design it makes total sense to not apply the deformation to the base mesh automatically. The workflow is more similar to painting a displacement texture than to subdivision based sculpting. As it is exposed in the UI as it was a standard subdivision based sculpting system, this often confuses users. As the main use case for having subdivisions in sculpt mode is to be able to control the surface noise, it does not make much sense that level 0 is not directly available for that.\n\n- **Unpredictable displacement interpolation in edit mode**: (To be checked with @JosephEagar ). It looks like it may not be possible to properly implement grid interpolation in edit mode due to numerical stability problems. \n\n- **No support for other custom data layers**: The only datalayer that is supported in Multires is the mask, which is hard coded. Multires does not have any system in place to support editable datalayers in the grids. Mode info in #80609.\n\n- **Depends on editable limit surface**: As the high poly version of the sculpt is stored as displacement on top of the limit surface, any other Blender tool that changes the limit surface will break it without any warning to the user (for example, changing the crease values in Edit mode). See #81958\n\n- **Extremely hard to develop and maintain**: Blender most advanced sculpting tools don’t rely that much on displacing vertices, but more on topology algorithms for calculating transformations (pose, relax, boundary, expand...). Making and debugging these tools to work on grids usually takes 70% of their development time (I measure it when developing the boundary brush). A feature that may require a slightly different topology query (which is often trivial to implement for ##Mesh##) requires an amount of development for Multires that is usually bigger than the tool itself. \n\n- **No friendly workflow with other softwares**: Having surface detail stored as displacement in Multires is convenient to work inside Blender, but what other software expect is to handle surface detail at render time with UDIMS and vector displacement textures (Blender supports both). If you have an animated scene with multires, for exporting it to other software you need to bake all the displacement at its highest resolution per frame, which is not ideal. Even if Multires displacement data can be stored as a separate file, it can’t be read by any other render engine. \n\n\n\n\n## My opinion\n\nThe main technical limitations are about exposing the grids directly to the sculpting code. Because of this, I think that it makes sense for Multires to be used as a different feature. By design, Multires use case is closer to being an alternative to vector displacement for rendering than to a subdivision based sculpting system. To me, it makes sense for Multires to support features like storing displacement into the grids, baking the deformation of modifiers to the grids, reshaping a base mesh based on a displacement, unsubdividing and storing the grids as separate files (it already does all that). What I don’t see any value is in being able to edit the grids displacement directly with the tools. For users, Multires should be exposed in the UI as something similar to baking a vector displacement texture to use in rendering, or “ptex based displacement”. After the fixes and the features added in 2.90, Multires is completely functional for this use case. \n\nI would rather prefer starting discussing the design of a dedicated subdivision based sculpting system and leave Multires for what it does well instead of keep trying to add workarounds a hacks to make it meet the requirements of something that was not designed for. We need to consider that supporting the existing and planned features (like sculpt vertex colors or layers) in the current Multires will take a lot of development time that can be used for something else. \n\nFor Multires, I imagine the workflow to be like:\n- The user creates a subdivision based sculpt with a dedicated subdivision based sculpting system (not Multires).\n- When done, the user adds a Multires modifier to the high poly version and uses rebuild subdivisions. This will convert the sculpt to a base mesh + displacement. It is the same concept as baking a displacement texture from the high poly mesh into level 0, but slightly more convenient as it does not require UVs and geometry will look exactly the same as the sculpt.\n- After having the new low res based mesh, the user can rig and animate the mesh with displacement.

I have described what my problem is [here ]]. I do not necessarily want to simulate clicking but it turns out that I cannot update the contents of 'Viewer Node' image block. Finally, I thought the best way would be to automatically have backdrop enabled. So I followed the instructions given [[ https:*blender.stackexchange.com/questions/72742/depth-data-works-but-not-in-background-mode | here ](https:*blender.stackexchange.com/questions/102790/how-to-trigger-lmb-click-events-to-activate-a-specific-view-node-and-update-cont) by *Sebastian Koch* thinking that I should be able to dynamically add/remove view nodes and update the contents of the image block automatically. Although I could access to the pixels, but But this does not happen!\nI wrote the right code to do exactly what I show in [this video ]] but the pixels in \"Viewer Node\" image block do not get updated, as they do in the video. Not only that, I tried activating newly-added Viewer nodes manually (as described [[ https:*blender.stackexchange.com/questions/102790/how-to-trigger-lmb-click-events-to-activate-a-specific-view-node-and-update-cont | here ](https:*youtu.be/YCv5qdKLkZo)) but I am still unsuccessful in updating the pixels in the image block. I also tried removing the image block in Python and then continue adding new Viewer nodes. But from the time I remove the image block its contents will always be zero even if I redo the rendering.\n\nThe only way I could successfully update the contents of the image block was after, first, I followed *Sebastian Koch*'s solution and then wrote some code to remove/add all nodes and their links to get either depth map or surface Normals and did the rendering again. But the whole point of me trying to store pixels into Numpy arrays was to avoid doing re-rendering to get around the IO overhead. I could have instead stored two files (for both depth map and Normal maps) throught two Output nodes with rendering only once.\n\nFirst, if this behavior does not look like a bug, I would appreciate the community provide me an easy solution to do what I want. Second, It would be great if you can improve Blender's Python API and add ways of easily accessing rendering results in memory so that people like me who want to do millions of rendering do not need to deal with the delays cause by IO to transfer rendering results from memory to hard drive and can easily store the results into Numpy arrays and store them on disk in chunks. \n\n", "Assign shortcuts: add support for enum menus\nOperating system: Windows-10-10.0.17763 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 388.13\n\n\nBroken: version: 2.80 (sub 74)\nWorked: (optional)\n\n\nFor group menus, can't assign shortcuts by right click, and no python tooltips on this. maybe it's not bug, but really need it.\n\n\nscreenshots:\n\n\n\n\n\n\n", "Geometry Nodes: Only re-evaluated log do update available attributes in drop-down menu\nBroken: version: 4.0.0 Alpha\n\nThis is a fairly insignificant UI bug.

I had initially thought it was simply a problem rendering in Cycles but for my first render, I forgot to switch from CPU to GPU and noticed it rendered fine. So I did a few more tests and it renders fine with CPU every time, but not with GPU.\n\n[VelvertTest.blend](VelvertTest.blend)\n\n", "Image sequence playhead for particle system textures never advances past first frame of sequence when particles are baked\nOperating system: Windows 10/64\nGraphics card: NVIDIA GeForce GTX 1060\n\nBroken: 2.93, 3.0.0\nWorked: n/a\n\nWhen I create a particle system that relies on an image texture containing an image sequence to control density, the playhead for that image sequence remains \"stuck\" on the first frame of the image sequence when I bake the particle system, regardless of the output length of the composition. This is true regardless of what type of image sequence is used (i.e. frames in a container such as .mp4 or .mov, or sequences of images such as .exr, .tif, or .png) or what playback options for the sequence are set (i.e. Cyclic and Auto Refresh can both be checked; it won't matter).\nRenders of an un-baked particle system using a moving texture to control particle density in Cycles are unusable.\nRenders of an un-baked particle system using a moving texture to control particle density in Eevee are occasionally usable (although unreliable: one must make absolutely certain that no frames are cached before attempting a render).\n\n**Expected behavior**\nMy expectation is that the playhead for an image sequence using a texture to control particle density would advance when the particle system is baked. It should appear both in stage preview and final rendered output that the source of particle emission appears to move, which is to say it should accurately track the black and white areas in the image sequence.\n\nCreate an empty Blender stage;\nAdd a plane to the stage;\nCreate a texture based on any black-and-white-only image sequence (i.e. a white circle whose position changes with time, superimposed on a black frame); the sequence can be either containered-image or discrete-image;\nCreate a particle system for the plane;\nAssign the texture to the particle system, leaving only the \"Density\" influence in the texture checked;\nMove the stage playhead to frame 0 of the composition;\nClick \"Delete All Bakes\" to clear any baked frames, also change number of particles in order to delete frames in memory;\nClick Play on the stage;\nHalo objects should be being emitted from the white areas in the texture as they move around in the texture (the emitter will appear to change position);\nMove the stage playhead back to frame 0 of the composition;\nClick \"Delete All Bakes\" to clear any baked frames;\nClick \"Bake All Dynamics\" to bake the particles;\nClick Play on the stage;\n\nSteps done in following file:\n[particle-density-demo.rar](particle-density-demo.rar)\n\nBoth on the stage and in rendered output, particles will be emitted only from the location on the plane that corresponds to the white area as it was on the first frame of the image sequence.\nAnd if someone could show me where in the code this stuff is handled, I'd be more than happy to take a look.", "Particle Info Node does not return particle information in light nodes\nOperating system: Windows 10 Home\nGraphics card: Nvidia GTX 1080 \n\nBroken: 3.2.0 e05e1e369187\nWorked: N/A\n\n\nThe [Particle Info Node](particle_info.html) does not properly output values when used inside light nodes.

On **X11**: Computer freezes for about 5 seconds before all monitors cut to black. After about 5 seconds on a black screen, the login screen appears and I can log in as normal, as if I logged out. All of the applications have closed.\n 2. On **Wayland**: Render finishes rendering, but many of the objects appear broken; they are semi transparent or appear as if they were using the holdout shader. Returning to the viewport causes all objects with transparency to flicker randomly and appear distorted. Occasionally, the desktop of the computer itself will become broken and artifacted, only logging out or restarting fixes it. This usually isn't possible, however, as after a short while everything all displays cut to a black screen. Unlike X11, however, the only way to recover from this is to restart the PC by holding down the power button.\n\nThis issue **only occurs on linux and does not occur on my Windows 10 partition**, even with the exact same settings and scene. It also only occurs when actually trying to render the scene. In the viewport everything works just fine, even on rendered view where everything looks the same as it should in the render.\n\nThis issue seems to occur regardless of the GPU Usage; even when I limit the GPU clock and power draw significantly it still happens.\n\nThe attached .blend file is an example of a simple scene which triggers the bug.

They can decide which tools and modes will use it. \n\nIf they don't want to change how X-Ray affects box/circle/lasso selection, they can use Automatic X-Ray. When they start to drag select it will turn X-Ray on, and when the selection is done X-Ray will turn off. They can decide which tools and modes will use it. \n\nInclude some operators. User can show any combination of them in the Header. If everything necessary for the tool and mode is enabled, the button for the operator will be lit up. It's modular, so there are many ways for the user to setup their shortcuts. Make new icons for Auto X-Ray and Select Through, the ones in my build were made by Alexey Adamitsky.\n\n**Viewport Facing Select**\nAt 4:17 in the video above.\n#109357\n\nBlender _does_ select unseen Mesh, and not in a good way like Select Through. If user can see some verts of an edge or face, they're potentially selectable regardless of their visibility. If it isn't truly random which unseen edges and faces this applies to, it may as well be. The 3 drag selection tools select the same wrong things, but if the viewport camera is moved or rotated, this will usually mean that different unseen edges and faces are now selectable.\n\nThe opposite is also a problem, where user cannot select visible mesh. If user zooms out, has a complex mesh, or a shallow angle on it, selection bitmap will only capture some of the mesh and give a patchy bit of what the user wanted. Long term, need to increase resolution of selection bitmap, whatever that would mean. Maybe Vulkan affects this in a positive way, maybe it has nothing to do with it. \n\nFor now I made Viewport-Facing Select to deal with this. Put it in Toolsettings. It works in near select, X-Ray, or both. When user drag selects with box/circle/lasso, it compares mesh normals to the viewport. If they aren't facing each other within the threshold, they won't be selected. Has a range from +/- 0.999999. Greater or equal to 0 means the mesh normal is pointed in the direction user has it set to. The higher they set the threshold, the more the mesh needs to be facing in that direction. A value of 1 should mean the viewport and mesh are aligned, but was only working from the front perspective (numpad 1) and from nowhere else regardless of ortho. Max threshold of 0.999999 is functionally the same as having it at 1 except it works from any angle. Negative values can select unseen mesh.\n\nAll Verts setting saves performance without compromise, because Blender doesn't select unseen verts. They're dimensionless, and since there's only one position for them to be drawn in, they shouldn't be in the selection bitmap unless they're visible.\n\nFront Verts will select verts based on their normals,. Some of the verts at the edge of a mesh are excluded. Verts of Front Face will fix that, it selects verts if they're part of a face with a viewport facing normal. There's also rear facing counterparts to these, they do the opposite where they'll select stuff pointed away from the viewport. Not sure if they're useful but it's easy to include.\n\nThe settings for edges work the same as verts. Using edge normals will exclude things the user probably wants to select, and Edges of Front Face will correct that. Same goes for face settings, except Front Faces are what give accurate selection. Faces of Front Vert will select faces that have at least one vert with a viewport facing normal. This means it can select unseen faces, which is what I'm trying to avoid, but maybe it's useful for something.\n\nSometimes user will be able to see a face even though it has a rear-facing normal, and VFS won't select it. Usually this is because they are dealing with two triangles that have no business sharing the same quad, but that's going to happen from time to time, and they'll need a way to select them. Besides turning this feature off temporarily, triangulating or otherwise fixing the mesh, single-clicking, or rotating the camera, they can drop the VFS threshold into the negative. How negative they go depends on what they're willing to live with, and it gets worse the lower they go. I keep it at zero, because at least I have a chance of noticing things I didn't select. Hard to keep track of random selections that you can't see. It's not perfect, but it's predicable, and should work with most geometry.\n\n**Object Origin**\nAt 7:35 in the video above.\n#109373\n\nMy implementation of this feature is incomplete, but functional. Circle and lasso are forced to select objects by their origin, while box cannot do this. Put a checkbox in the Keymap so user can control this. Call it Select Object Origin. With my build box origin seems ok, but circle is a little off and lasso has enough problems with non-origin that I left it out. There's an addon that does this fine though from what I've been told. I looked at it but I couldn't figure out how to give object mode access to vert info, just kept getting errors so I left it at that for now. Addon is called [X-Ray Selection Tools](DaLdj)\n\n**Unsolved Mesh Select Issues**\nAt 8:32 in the video above\n\nIntersect doesn't work with Touch or Enclose face in X-Ray and Select Through. Don't know why, looked at it a few times, doesn't make sense to me. With my build it will fallback to a Center select instead. Figured it's better to do something close to what is expected rather than nothing.\n\nEnclose face works in near select, but it's hard to use if user can't see all the verts of a face. If there is a visible face, but some of it's verts that would otherwise be on screen are behind something else, the selection bitmap thinks they don't exist. This means that it also thinks that part of these faces are outside the selection area, even though they aren't, and they get excluded from selection. One thing user can try is avoiding the selection bitmap entirely. Turn on Select Through, and set Viewport Facing Select to work in X-Ray, Verts of Front Face, Edges of Front Face, and Front Faces. Threshold at zero is best in my opinion. Now they get a decent result, but have to deal with the baggage that comes with Select Through and VFS. They don't always get everything they can see, at least when encountering some weird faces that have triangles pointing in very different directions. Also, they're going to select like X-Ray so if there's something that is facing the viewport, but they don't have line of sight, they're going to select it without actually seeing it.\n\n**Drag Direction**\nAt 9:56 in the video above.\n#109726\n\nBlender let's you assign a direction to click-drag in the Keymap. There are 8 of them, which is nice, but it's confusing and inaccurate if all you need are 2. Provide some alternatives in Preferences->Input->Mouse. I'd like to put them at the top of the keymap in that preferences area, but I noticed how that thing will disappear if you load a keymap or use one other than the default. Didn't look into it yet. \n\nKeymap Drag Direction has 3 options. Eight, which is what Blender does, Left Right, and Up Down. The tradeoff for the new ones is that they're exclusive. If you use Left Right, the only Keymap items Blender will match with are Any, Left, and Right. Unless something has been manually set to a direction, there shouldn't be anything besides View Axis, the ones where you hold ALT and Middlemouse while dragging in the direction that corresponds to the view you want.\n\nWith Blender's way, try to set Box select to Extend when dragging left aka West, and Subtract when dragging right aka East. If user doesn't initiate a mouse drag within 45 degrees of left or right, they get a Tweak Event instead of what they expected. There's a way to make this work better using the keymap alone. They can set Extend to Any, and Subtract to East, Northeast, and Southeast. The Keymap item set to Any needs to be after the other 3 or they'll be undetectable. Not intuitive, and I didn't figure out this was possible until after making this feature.\n\nWith the new ways I made there's 3 operators that will set drag direction. If a Keymap item is undetectable, it will warn the user about it. Not ideal, but nothing bad will happen, it's just telling them that this Keymap item won't do anything because Blender can't see it anymore.\n\nDrag detection has some perpindicular bias. If the user is on the Left Right setting, and they drag up or down far enough before moving to the right, they're going to get the Left Keymap item instead of the Right Keymap item that they intended. If they're on Up Down, and move horizontally before going up, they would get the Down Keymap. With Blender's Eight way, assuming they set it like I described, the dominant Keymap item is the one that is set to the Any direction. The Left Right and Up down options are a lot more precise so it's hard for this to happen. The Eight way calculation rounds to the nearest int, so it treats every mouse drag within 45 degrees of a cardinal direction like it went straight vertical or horizontal. This problem can be mitigated by increasing drag theshold in Userprefs->Input->Mouse.\n\n**Selection Radius**\nAt 12:48 in the video above.\n#109729\n\nSingle-click an edge, vertex, or facedot and there's a pretty big area the user can grab it from. Faces in near select have zero radius, so the cursor needs to be right on top of them. Make this adjustable and consistent. Preferences->Editing->Miscellaneous-> Adjustable Click Select is where I put it, but that is not a good spot. It makes faces act the same as the others, and the user can change the size of the selection radius. Blender gives unselected mesh a slight bias, this can be turned off. Very minor detail that would not likely be noticed.\n\n**Conclusion**\n Nothing is really done all the way, but it is closing some gaps. Lot's of things can be moved, renamed, tweaked. That's what I'd like to do, and maybe some of it can make it into real Blender.\n\n", "Rip edge-move for curves\nCurrently with meshes you can press Alt+D to add a vertex at one side of the verts edges and drag it *(based on the mouse cursor location)*.\n\nThis same behavior could be added to curves.\n\n- the basic behavior with single vertices selected is simple\n- with multiple segments are selected this becomes more involved (see how this works for meshes).", "bmesh.ops.subdivide_edges doesn't report all inner edges in 'geom_inner'\nBroken: 2.91, 2.92 master\nWorked: never?\n\n\nI'm not sure if it's a bug or if there's some underlying reason for this behavior.

We can work around this by iterating all **vertices** from 'geom_inner' list, and taking all edges linked to them that are not also part of the 'geom_split' list returned by the op, but it feels like this information should just be provided in the 'geom_inner' list.\n\nLoad the attached file and run the script.\n\n[subdivide_geom_inner_issue.blend](subdivide_geom_inner_issue.blend)", "Measure Tool does not abide by snap settings.

In the modal operator equivalent (Shortcut C) it's just about pressing + and - or using the scrollwheel but this is not an option for the Tool. Generally there are no shortcuts for Tools before they are initiated. If the settings need to be changed then this needs to happen in the Tool Settings in the header or sidebar.\nBut changing the radius via that slider in the settings is awkward and appears visually glitchy since it's intersecting with the UI itself.\n\n\n\n## Proposals\n\nSo how can this be fixed. Ideally the solution should be as straight forward as possible without reshuffling the keymap. But it is very important that this is a general solution that can also be used for other brush-like Tools in the future (like proposed retopology tools that also rely on a brush radius)\n\n**1. More integrated modal shortcuts**\n\nOnce a Tool is initiated (usually by click & dragging) it uses the modal operator. This means that when using the Circle Select Tool and click & dragging, the radius can be changed with the mouse wheel & the + and - keys. \nThe current issue with this is that the Gizmo drawing is conflicting with the Tool Radius and that any changes to the radius are not updated in the tool settings.\nKeeping these 2 more in sync would be one solution or at least a great added feature.\n\n\n\nIt should be updated to the way the annotate eraser tool works but with more accessible shortcuts for radius changes if the mouse wheel is not an option (pen users)\n\n**2. Include Brush Tools in more modes**\n\nAnother solution is to redesign the Circle Select Tool (and any tools, present or future, that work similarly) as a brush like in sculpt mode or the painting modes.\nThis means that when the Tool is active it does have a set of shortcuts that can change the tool settings before the tool is initiated.\n\n**Conflicts**\n\nAlmost all are already taken like the typical F for brush size changes. It's not clear what shortcut can be used. \nAlso any shortcut that would be available must then be exclusively used for those brush tools to avoid any conflicts. \n\n**Solutions**\n\n1. Find or make an available shortcut for brush tools radius. But this shortcut then needs to be left exclusive of those tools.\n2. Override needed shortcuts when brush tool is used (In this case F for the radius). This does introduce difficulties and extra tool switching in edit mode though. \n3. Reuse the shortcut C that is used for the Circle Select Tool to change the radius once the tool is active. This will be awkward and incompatible with future tools that will work similar though.\n\n## Open Topics\n\n- Can it be achieved to use both solutions to improve brush like tools?\n- Are there possibly other ways of solving the conflicts in proposal 2?\n- For proposal 1, what shortcuts could be better for adjusting the brush size? + & - are on the numpad and the brackets are too far to the right and on for example German keyboard layouts not very accessible.", "Texture Paint mode tools swap when exiting maximized area\nOperating system: Linux-5.17.5-76051705-generic-x86_64-with-glibc2.35 64 Bits\nGraphics card: Quadro RTX 6000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.68.02\n\nBroken: version: 3.3.0 Alpha\nWorked: unknown\n\n[texture_paint_tool_swapping-2022-05-10_12.52.16.mp4](texture_paint_tool_swapping-2022-05-10_12.52.16.mp4)\n\n- Go to texture paint mode\n- open second image editor\n- maximize the area of the 3D viewport\n- change the active tool\n- un-maximize the area\n", "Sculpted models in Solid or Wireframe viewports do not update in other Material or Rendered viewports when changes are undone (Undo).

However, I also want to be able to see how the sculpt looks under more finalized lighting settings in real-time while I edit and experiment with different sculpting or placement of facial features, for example.\n- I am constantly undoing brush strokes in a sort of error-correction method of sculpting. Naturally, reducing undoing strokes would be more efficient overall, but not being able to see the reverted mesh from undoing strokes absolutely debillitates confidence of an artist when they're suddenly not working on the most updated model.\n- This can cause bad sculpting errors as one looks from one viewport to the other to \"sanity check\" or simply check progress and be fooled into thinking that the models are synced, when they're actually desynced. The artist might not notice this and continue sculpting, which will update both views again, but it can cause unintentional sculpting errors.\n\nI'm not sure if this was a conscious design choice (2.82 also has this problem. I did not test pre-2.79 versions), but if it was, it makes absolutely no sense why there is even the possibility of anything desyncing between viewports, no matter how the artist works.

Currently, there are some inconsistencies and confusing behavior that need to be addressed. Here is a list of current issues and some new proposals.\n\n - **Brush Radius:** Currently, the brush size can be changed via this slider in draw mode.  The name displays \"Radius\" and the tooltip reads \"Radius of the brush in pixels.\", but this is not consistent with the thickness of the strokes. If the user sets the **radius** to 100px and the *Stroke Thickness* option in the object data properties is set to *Screen Space* the stroke has a **diameter** of 100 pixels. If the *Stroke Thickness* is set to *World Space* the stroke has a **diameter** of 0.1 meters. A simple solution is to change the UI name from \"Radius\" to \"Size\" and clarify in the tooltip that the thickness or diameter of the stroke is meant.\n - **Radial Control:** When the user changes the brush size via the radial control (shortcut {key F}) the control has a **radius** of the given pixel value, not (like mentioned before) a **diameter** of the pixel value set.  \n - **Brush size in World Space** When the *Stroke Thickness* in the object data properties is set to *World Space* the displayed thickness of the strokes in that grease pencil object are calculated via the following formula: `((line_change + stroke_thickness) * pressure * pixel_factor) / 1000.0f` E.g. when all adjustment values are set to their default value then **1px (stroke thickness) = 1mm (world space)**. Currently, there is no way for the user to know this. The UI gives no indication of this and the manual also does not mention it. A possible solution is to change the units of the brush from pixels to meters and also do the right conversion so that the size is correctly displayed in the UI.\n - **Drawing in screen space/world space:** The user can change the stroke thickness (screen space/world space) in the object data properties. That means that *all* strokes in the grease pencil object will be either drawn using the screen space thickness in pixels or the world space thickness in meters.

Cycles appears to force some sort of rounded/inverted cylinder normal at some point after the BSDF, leading to shading artifacts.\n\n\n\n\nNote the line down the middle of the strand/curves on the Cycles version. This is usually at the point where the (default) normal is facing fully away from the light source.\n\nThis happens on both the legacy particle system as well as the newer Curve based hair. It happens on both Rounded Ribbons and 3D Curve primitives.\n\n**Longer version**\n\nI want to render stylized fur. The approach I use is to copy the normals from the underlying mesh to the particle system or hair curves, and disable shadows. This makes a very smooth, toon-like shader.\n\n\n\n\nThis is based off of my old addon, encode-normals but normals passed as attributes from geometry nodes have the same issue, as do normals set right in the material itself, so it's not an issue with my addon or node tree.\n\nIn the example blender file, I have two planes facing upward. One has a legacy particle system and the other has a new hair curve. Both sets of strands/curves have a material where the normal is forced to be (0, 0, 1), or straight up, to show the base case. \n\nIn Eevee I get the toony flat shading, where each strand is basically a solid color. \n\nIn Cycles, I end up with part of the strand in shadow, and if you look closely the emulated rounded normals appear to be an \"inside out\" cylinder, so the line tends to show up where the light direction and normal of the fake \"cylinder\" are perpendicular (i.e., where light is grazing the outermost part of the cylinder)\n\nI can't turn this rounded normal off or override it. It's coming from something outside the BSDF. This completely breaks my stylized shader in Cycles and is an unintuitive behavior. Normals can be overriden on a material in any other situation/primitive that comes to mind.\n\nSteps I've tried:\n1. Setting normals from encoded vertex colors (addon)\n2.

I have an environment with foliage billboards that appear like they are slightly head-locked and they sway around a lot when moving in VR. I later realised I could reproduce similar artifacts outside of VR and then realised that disabling denoising avoided the artifacts in the editor and in VR.\n\nIt seems that Eevee's denoising introduces some kind of latency related to how the alpha blending is handled which results in temporal, visual artifacts while the viewport's perspective is changing.\n\nI'd say the reproduction below probably doesn't represent how significant the artifacts feel in VR but I think it highlights the same underlying issue (the same two workarounds that affect the editor, also help in VR).\n\nTurn on Viewport Shading: Material Preview or Rendered\n\nDelete cube\nAdd plane\nAdd material (default principled BSDF is fine, though in my case I'm working with emissive shaders and I have a modified build of Blender supporting equirectangular image textures that let me access their alpha channel)\nSet material Base Color to an Image Texture.\nCreate a new image and generate a Color Grid to set as the base color. (with or without Alpha)\nSet material blend mode to 'Alpha Blend'\n\nGyrate/pan/orbit the viewport view. (Note the artifacts are related to the viewport navigation that needs to move around, and just moving/rotating the plane itself won't show artifacts)\n\n(For the Color Grid the artifacts mainly look like shimmering, and glints on the white letters. That's quite different to the original artifacts I saw in VR for my use case but still it seems to represent the same underlying issue.)\n\nUnder render properties, toggle Viewport Denoising and perform the same viewport movements to compare.\nWith Viewport Denoising back on, switch to using Alpha Clip instead of Alpha Blend and again compare.\n\n[eevee-denoise-artifacts.blend](eevee-denoise-artifacts.blend)", "3D Viewport clipping support\nThis task is to keep track of which features support view-port clipping (Alt-B).

[ "Tooltip for the Drag tool setting\n## Issue\nRecently for Blender 3.0 the \"Drag\" option in the header tool settings was included for most active tools.

Finally, hiding some interface elements will not have business functionality and a bunch of complications in the code.\n\n**More about the problem:**\nThe hide (in interface) and unavailable (for processing) sockets is now used to hide the visible (used) list of sockets.\nThis has consequences:\n1. All sockets exist all the time.\n2. Links to them still exist.\n3. It is not possible to create new sockets without code complexity (previously, for node groups new sockets are created manually in some code places).\nAnd this brings a lot of complexity to the code.\nJust examples: [D16784](D16784), [D16772](D16772), 2b4cb893e7, ...\nAnd trubbls for python users: #103395 (Node: Incorrect node socket indexing when connecting with python)\n\n**The main task:**\nAt the moment, this problem can be solved in several parts :\n1. Different sockets for different node configurations:\n a. Group nodes create their sockets based on node tree declaration: [D16850](D16850).\n b. Individual nodes create a statically assigned set of sockets depending on the state of the node: [D17081](D17081).\n c. Nodes for working with multiple data layers (shaders, compositor): based on scene data or some other data. There may be subtleties here. Example task: #70802.\n d. Physics Nodes: Based on what data should be stored in the simulation.\n2. Support for multiple types on a socket as generic socket type:\n a. Argument list of supported types for socket declaration.\n c. Type of socket declaration, that mean evaluation-time type of socket based on context (similar to template node groups)\n\nAlso, since the constant deletion and creation of sockets has its consequences, some behavior needs to be recreated. Now it will have more control, which in theory should improve usability:\n1. Simulating data storage for a temporarily remote socket [D17136](D17136) :\n a. It is possible to store data of node group sockets.\n b. Value conversions when changing the group socket type.\n2. Handling implicitly deleted links for their possible return to their original place.\n\n**Code cleanups:**\n1. The result of a complete switching to explicit processing of real sockets may be the complete removal of visibility flags for sockets. Or at least move them to the category of deprecated.\n2. As well as the complete removal of the code that processes them." ]

[ "geometry nodes are recalculating when adding a disconnected node to the tree\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12\n\nBroken: version: 3.0.0 Alpha\n\nThe tree is calculating unnecessarily, for example:\n\nadd a lot of points to a cube, and instance some cubes on it. Enough so that the delay is noticable when you try and tweak the cube size.\n\nNow press shit a, and S to search, and type val, then click on the value node to drop it down. The tree is calculating before the node appears, even though it's not going to be connected to anything at this point. This is extremely problematic for complex trees, because the user will have to wait to drop the node down, and then again as soon as they wire it up. \n\nThis may also mean that the node tree isn't being smart about only updating the result of nodes which have no changes either of their own parameters or of other parameters/links/nodes downstream. This is a massive performance problem if it's the case. I got around this problem in my real time compositor addon by storing the hash of all downstream paramters in each node, so that it only recalculated portions of a node tree where the downstream hash had changed, rather than the entire thing. It's a huge performance boost if you can do that here too. In my case I only stored hashes in nodes I choose to cache, and then store the result on disk, but probably in geometry nodes it there could be a cache node that allows the user to choose between disk or ram.\n\n", "Geometry Nodes is re-evaluated even when nothing changed in the main tree\nBroken: version: 3.0.0 Alpha\nWorked: Never\n\nWhen I add a new node to a nodetree things can be slow, even if the node is not connected to the nodetree.\n\n* Open [wavy procedural wall ](wavy_procedural_wall.blend).\n* Add any new node (e.g., Attribute Fill)\n* Delete the node, add another node, tweak the values of the node ...\n\nEven though the nodes are not connected to the maintree it is slow to tweak them / add them/ ...\n\n**Cases that need to be optimized**:\n- [ ] Add new unconnected node.\n- [ ] Tweak unconnected node.\n- [ ] Delete unconnected node.\n- [ ] Add reroute\n- [ ] Object is moved but the node group does not depend on the transform." ]
