This is also a first pass, there are likely many more use cases/topics to be discussed.\n\n# Problem\nCurrently, when appending a data-block, Blender appends (i.e. link and make local) the ID and all of its dependencies.\n\nThis means that if a single object in appended ten times, you will get ten copies of the object, but also of its meshes, materials, animations, etc.\n\nThis behavior may be fine in some cases, but not in others.\n\n# Default Behaviors\n## Generic Considerations\nTo avoid having many copies of the same ID, the first appended copy needs to be re-used for the subsequent appends.\n# Do we always re-use that ID, even if it has already been modified by the user locally?\n *Think first appended ID should always be re-used, reliably detecting modified IDs compared to linked one is possible, but tricky and not very efficient (RNA diffing)... There could be a mechanism though to break that reference such that next append creates a new copy of it.* **No diffing.** User has ways to make an existing local ID not re-usable anymore, and to force not re-using an ID when appending again. \n# ~~Could we use the UserPreferences settings for data copying, to decide which ID types we systematically create new copies for, and which ID types we try to re-use previously appended ID?~~\n\n## Specific Cases\nHere is a list of different use cases, possible behaviors being:\n* Link.\n* Append (Link + Make Local, aka new copy).\n* Re-use of previously appended local ID.\n\n### Append Material\n| Data type | DEFAULT | Alternative Behavior 1 |\n| --- | --- | --- |\n| Material itself: | re-use | *duplicate* |\n| Image: | NA | re-use |\n| Node groups: | NA | *duplicate* |\n| Actions: | NA | *duplicate* |\n\n### Append Object\n| Data type | DEFAULT | Alternative Behavior 1 |\n| --- | --- | --- |\n| Object itself: | *duplicate* | *duplicate* |\n| Obdata: | re-use | *duplicate* |\n| Actions: | re-use | *duplicate* |\n| Materials: | re-use | Apply Materials Rules ? |\n\n### Append Collection\n**Collection itself:*** In case of Empty-based instantiation:\n***In case of ViewLayer-based instantiation:** Object: *same as above for Object case?*\n\n# User Customization\n## Change behavior in UserSettings\nShould user be able to change default behavior in user settings, or only on a case-by-case basis when actually linking/appending IDs or assets?\n\n## Change Behavior in Asset/File browsers\nShould user be able to toggle options like \"Link everything\", or \"Never deduplicate\" ? etc.\n", "Boolean modifier: Self Intersection fails when mesh object is same for both operand types\nOperating system: Win10 (21H1 19043.1348)\nGraphics card: GeForce 1080Ti (496.76)\n\nLatest 3.0 (December 02, 02:20:21 - 9cec9b4d6e33)\n\nOperand type `collection` did not consider `self intersection` with certain condition.\nIt fails when mesh object is same for both operand types\n\n- Open .blend file\n- Change operand type to `Object`\n- Uncheck `Self Intersection`\n- Switch back to `Collection\n\nTest File:\n[boolean.blend](boolean.blend)\n[2021-12-03 13-50-41.mp4](2021-12-03_13-50-41.mp4)", " Verts/Faces instantiation recursion: child items reappear if they are collection instances\nOperating system: kubuntu\nGraphics card: nvidia\n\nBroken: 2.82a - 2.90.1\nWorked: I don't think it did in the 2.8 series\n\n\nThe lower plane is the face-instancer of a blue sphere, and a collection instance that consists only of the peg (the one to the right).

Set one of the cubes on the end to animated.\n5. Select the constraint between the animated cube you just made and the next one in line and set all limits to 0.\n6. Select the next constraint in the line and set all angular rotation limits to zero except the z angle upper limit, set that to 90.\n7. Set a keyframe on the upper limit Z axis of that same constraint on frame 1.\n8. Go to frame 40 and set the upper limit Z axis to 20 and keyframe it.\n9.

I tried it on the public release of 3.1 and encountered the same issue. Today I have reproduced it on 3.2.0. I do not believe this has ever worked.\n\nWhen rendering a view of a smoke simulation (or any volumetric shader) where the material on the far side of that simulation/volumetric uses displacement, there seems to be an effect surrounding and inside the volumetric which causes the displacement texture to jitter, its reflections rapidly altering between frames causing an appearance almost like the texture/object or light source is vibrating/moving. The effect, when viewed on small smoke simulations, appears almost like heat distortion and may be useful for achieving that effect in other desired scenarios. When viewed through large volumetric shaders (such as fog) it creates an effect over the entirety of the object using displacement and is very distracting.\n\nFrom a default Blend, create an object. On this object create a texture that uses displacement and has displacement & bump truly enabled. Then, run a smoke simulation either via a quick smoke or particle simulation or, create a large object that then uses a displacement texture. Then render the scene such that the object with the displacement texture is on the far side of the smoke simulation/volumetric object. A well-lit environment, dense smoke, and a complex texture (high scale noise for small fine displacement/bump details) that makes use of glossy areas will make the effect easier to see. Disabling/removing displacement from the texture (and disconnecting the socket) will correct the issue at the cost of loss of displacement.\n\n\nThings I have tried to get around this problem:\nI have drastically increased, decreased, enabled, or disabled, the following settings to no avail.\nWith regards to the domain:\n- Adaptive domain\n- Noise\n- Empty space: higher values (up to 1.0) did seem to have an influence on the size of the distortion area but could never eliminate it. \n- resolution divisions\n- time scale minimum\n- precision volumes\nWith regards to the smoke texture:\n- Sampling\n- interpolation\n- homogenous\n- step rate\nWith regards to rendering:\nOptix denoising and openimage denoise - I will attach an example of each.\nvery high samples\nI also made sure/tested a domain and/or smoke which does not pass through the surface or near the actual surface of the displacement texture. \n\n - attaching several GIF examples at lower framerate playback.\nI believe the jittering in the full foggy stadium in the reflection of the moon and distance areas when displacement is off is simply due to the lower samples I used for that test render.\n[Bug.blend](Bug.blend)\n\n\n\n\n\n\n\n\n\n[31 displacement issues.mp4](31_displacement_issues.mp4)", "modifier display/render driver not responding.\nOperating system: Windows-10-10.0.22621-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 527.56\n\nBroken: version: 3.4.0\nWorked: unknown\n\nIf I have my Mask display/render driver from another objects display/render setting, changing controlling obj disp/render doesn't take effect without coaxing.\n\n1.

When using touch, two fingers will scroll up and down. In Blender, two finger touch should work like an Apple touch pad or Apple magic mouse: two finger movement will orbit the view; holding down command zooms, holding down shift pans. Instead, it simply does nothing.\n\nBlender.app, default cube. Place two fingers down on a Wacom Intuos Pro tablet and move them around; it should orbit, but nothing happens. Well, the bottom status bar flickers back and forth as though command/shift or alt is pressed. \n\nThere are two reasons why this happens. \n1. Blender has incorrect Cocoa/AppKit code. I worked on AppKit for ~13 years at Apple. Below is a diff that addresses some of the issues. The code attempts to keep track of m_multiTouchScroll, but this isn't needed. It should key off of hasPreciseScrollingDeltas instead. I tested this diff with: Apple Magic Mouse, old school Apple scroll wheel mouse, Wacom tablet; all things work the same (except Wacom, which has the bug I'm reporting fixed). There is also a comment about intuos5, but that seems to be incorrect and outdated, but I don't have an Intuos 5 to test with.\n\n[0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch](0001-Fix-scrolling-with-wacom-tablets-using-them-as-a-tou.patch)\n\n2. Wacom's tablet touch drivers do link-checked behavior based on the bundle identifier \"org.blenderfoundation.blender\". In other words: they change the touch behavior when they see the target application is Blender. Wacom needs to fix this, but I'm not sure how to log a bug report for them.\n\nTo prove this, I created the sample application:\n\n[TabletTest.zip](TabletTest.zip)\n\nThe sample application has the blender bundle identifier set, as seen in this screen shot:\n\n\n\nIn ViewTest.m I log the flagsChanged:\n\n``` - (void)flagsChanged:(NSEvent *)event\n```\n{\n NSLog(@\"%@\", event);\n}\n```\n```\nIf you run the app and do a two finger scroll in the window you will see some flagsChanged logged, which is very strange because Shift/Alt/Cmd have not been pressed! Wacom is faking them for some reason, and changing the scrolling data, which messes up Blender.\n\nChange the applications's bundle identifier to \"org.blenderfoundationXX.blender\" (you can simply edit the info.plist) and run it again; it will then behave correctly.\n\n\n\nI don't know how to fix item 2 for Blender; I'm fixing it in my own build of Blender by changing the bundle identifier to org.blenderfoundation.bl3nder after it is built. I looked into identifying the events, and I can could identify the source as coming from the wacom driver but I can't fix them. \n\nI'm trying to find a contact at Wacom to have them fix this, but once it is fixed we still need item 1 fixed. \n\n\n\n", "Unable to see cursor point properly when R/S/G keys are used\nOperating system: macOS-12.5-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 575 OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.8.101\n\nBroken: version: 3.2.0\n\nAccessibility issue: Unable to see cursor point properly when R or S or G keys are used\nPlease fix copy code from 3D Viewer when push the R or S or G appear color there then paste code into Timeline to become color can see without full black.\n\n- Cursor point can not be seen properly when R/S/G keys are used in timeline (in particular theme as shown in video)\n\n\n\nSee youtube Fh6OYqW2AfU\n", "Simple ball shooting animation not working as before\nOperating system: win7\nGraphics card: gtx970m\n\nBroken: 2.80, 2.81a, 2.82a, 2.83-1239cab11ff9\nWorked: 2.79b\n\nI've tried to create a simple shooting ball and while the effect was ok with blender 2.79b it won't work the same\nway on the specified \"broken\" versions.

This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. 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.", "The display will be damaged when the node editor in Fullscreen Area mode (ctrl alt spacebar)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: AMD Radeon(TM) R7 Graphics ATI Technologies Inc. 4.5.14736 Core Profile Context 20.11.1 27.20.12033.2007\n\nBroken: 2.93 as well as version: 3.0.0 Beta\nWorked: Haven't tested before 2.93.\n\nThe display will be damaged when the node editor in Fullscreen Area mode (ctrl alt spacebar).\n\n* Switch workspace to Geometry Nodes\n* Add a new Geometry Nodes modifier/datablock\n* Ctrl+Alt+Space to go fullscreen (not Ctrl + Space)\n* Select or move a node\n\nFile:\n[bug.blend](bug.blend)\n\nGIF：\n", "Incorrect Fresnel layer weight shading on backfacing geometry\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: Radeon (TM) RX 470 Graphics ATI Technologies Inc. 4.5.13587 Core Profile Context 20.4.2 26.20.15029.27017\n\nBroken: version: 2.91.0 Alpha\n\nFresnel layer weight creates a sharp boundary instead of a smooth falloff when viewed on backfacing geometry.\nIn this example there are 2 hemispheres with the same material, but the left one has inverted face normals.\n\n\n[fresnel bug.blend](fresnel_bug.blend)\n", "Geometry Nodes Mesh Boolean unexpected difference result\nOperating system: macOS-13.1-arm64-arm-64bit 64 Bits\nGraphics card: Apple M1 Apple 4.1 Metal - 83\n\nBroken: version: 3.5.0 Alpha\nWorked: none\n\nGeometry Nodes Mesh Boolean Difference does not work as expected.\nNode setup:\n\n\nUnexpected boolean difference:\n\n\n- Open the attached .blend file\n- Press G to move the selected Cube.001 and the small cubes will flicker.\n# At certain positions of Cube.001 some of the small cubes will disappear when they should not.\nThanks!\n[test06.blend](test06.blend)\n" ]

[ "Make saving of `quit.blend` on exit optional\n### Description & Scope of Problem\n\nEvery time Blender quits, when it has something on the undo stack, it will write the current \"undo file\" to `${TEMPDIR}/quit.blend` ([manual](open_save.html#last-session)).\n\nSaving `quit.blend` can take a while when the file is large. While the file is being written, Blender's UI is gray and unresponsive.\n\nThe problem is not pressing, as usually it takes considerably longer to load the files in the first place. I've asked some artists at the Blender Studio and they didn't really consider the delay when quitting Blender a practical issue. Still, it gets somewhat in the way of quickly testing things with various production blend files, so it could be seen as an issue for developers more than for artists.\n\n### Possible Solutions & Impact\n\n**Simplest solution:**\n\nAs a solution we could introduce a user preference \"Save Recovery File\" that is enabled by default. Disabling this option would:\n- Avoid writing `quit.blend`.\n- Remove the \"File ‣ Recover ‣ Last Session\" menu item.\n- Remove the \"Recover Last Session\" button from the splash screen.\n\n**Alternative solution:**\n\nThe \"Recover Last Session\" operator does not poll the filesystem from its poll function. This means that the operator is available even when the file `${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", "Menu label does not update after \"Remove Shortcut\" from context menu\nOperating system: Darwin-19.5.0-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 455 OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.9.15\n\nBroken: version: all\n\nAfter \"Remove Shortcut\", the menu label is not updated properly.\nJust for a moment, but it's noticeable.\n\n**Only in the case when the \"Remove Shortcut\" menu item (mouse cursor actually)\nis located above the deleted item or above separator.**\n\n", "Folder permission dialogs appearing when Blender is started for the first time in macOS Monterey\nOperating system: macOS-12.1-x86_64-i386-64bit 64 Bits\nGraphics card: Apple M1 Apple 4.1 Metal - 76.3\n\nBroken: version: 3.0.0\nWorked: never (macOS Monterey issue)\n\nWhen running a newly downloaded version of Blender (or running a new custom build) in macOS Monterey, Blender asks for permission to access the Desktop, Documents and Downloads folders. This happens even before the main Blender app window is visible.\n\nThese permission dialogs are triggered, because Blender tries to access/enumerate those folders at startup. However, I think it is a bad UX when you have to accept three permission dialogs before Blender is visible. And when a user chooses to not allow Blender access to those folders, it might be hard for them to restore access to those folders at a later stage.\n\nI think Blender should only ever try to get access those locations when a user explicitly wants it to, i.e. by browsing those folders using Blender's file browser or when opening a file from said folders.\n\n\n\nI'm pretty sure this behaviour started appearing recently. Not sure whether something in Blender has changed or that macOS got more strict.\n\n1. Be on macOS Monterey.\n2.

The issue persists even between leaving and re-entering rendered mode in the viewport, until the user manually clicks to toggle the UI setting directly which resolves the problem.\n\nBased on the default startup or an attached .blend file (as simple as possible).\n\n1) Open default scene\n2) Open console window/scripting workflow,\n3) Enable cycles and enter a viewport into rendered mode\n4) With Default cube selected, type: C.object.cycles_visibility.camera = false\n5) Notice how viewport scene does not update; but if you move the mouse over the property panel:Objects/Cycles settings, you'll see the draw refresh will show the camera visibility turns off\n6) Exit and re-enter rendered mode in the viewport, to find the issue persists (cube is visible to camera)\n7) Press render to notice that the setting however is reflect in render (cube will not be visible to camera)\n8) Manually toggle the camera visibility setting in by clicking the tick box twice, to verify the setting works when done by hand; and see that now the cube does not appear in the viewport (as expected).\n9) Repeat for reverse; ie turning setting to True when initial camera visibility is false.\n\nNote I also tested this and found the same issue with the Glossy visibility using a similar process (adding a mirror-like object next to the cube), so I expect this is true for all of the cycles object visibility settings. \n\nVideo demonstration, happens in any scene including the default\nview?usp=sharing\n\nWhile I agree this is less of an issue since ultimately the correct results appear in render, this is an issue for addons that control this setting and confuse the user as prior to render, there then appears to be a discrepancy between the viewport visibility and the panel settings.

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" ]

[ "Design: Shading: Extend Clamp and Map Range nodes to work with Vectors\nI'd like to make these nodes work with vector inputs and outputs.\n\nIt's unclear to me as the the best way of doing this. \n\n\n\nSome options:\n\n - **Separate Nodes** : Create separate versions of these nodes with Vector sockets.\n\n - **Dynamic** : Use a dynamic socket. This is better from a UX perspective but how do we show this? For these two nodes, they are pretty pointless without a value input so the edit control could be hidden. The node then operates accordingly depending on the input link. \n\n\n\n- **Mode Switch** : Add vector input and output sockets and add a mode switch to hide the unwanted input socket. \n\n- **Double Sockets** : Add vector input and output sockets and depending what is connected. For vector only input, `Vector` > `Float & Vector`. For float only input, `Float` > `Float & Vector`.

More advanced implementations could include options for alternate, lightweight representations of shapes in the Blender scene, e.g., exploiting instancing, custom viewport rendering that does not require importing the mesh data, etc.\n\n@charlesfleche discussed the following suggestions re USD shape support on the `pipeline-assets-io-module` Blender chat channel on 22 Sep 2022.\n\n---\n\nOur main use case is to represent collision objects. For performance reasons we can feed simple collision objects to the physic component of the game engine. For example, rather that computing a collision with a complex character head that as many faces, you can define a simple sphere that is much faster to compute collision against.\n\nBut sometimes simple shapes are not enough: in this case we still want as fast as a collision computation as possible, and use a convex mesh to approximate the visual shape as much as possible. And when we really, really require high precision we'd use a mesh that can be complex and convex.\n\nWe also have the concept of collision Level Of Detail. The typical example is a fence:\n\n- you don't the player to walk through the fence, but for that purpose you can approximate the shape of the fence with a single parametric box\n- but you still want a bullet to go through the holes of the fence: for collision with ammunitions, you'd use a more detailed mesh\n\nBut not all DCC support parametric shapes, so for simplicity (and for now), we are still importing USD shapes as meshes in the DCCs, but on way back to USD we compute the bounding volumes of the requested shape. In practice, it looks like this:\n\n- In USD: `UsdGeomCube` MyObject_BOX with a size attribute + xform\n- In the DCC: we extract the dimension of the box from the scale component of the transform and generate a box mesh, with custom code ran at import time\n- DCC user is editing the box\n- In the DCC: the object is a _BOX, we compute the Box Bounding Volume and store the x, y, z dimensions as in the xform as scale\n- In USD: `UsdGeomCube` MyObject_BOX wih a size attribute + xform\n\nIt is not great because the users don't have the same representation in engine vs the DCC. In engine they'd handle Radius and Height parameters, in the DCC it's a bunch of vertices.\n\nSo the idea, for Blender, would be to leverage the geometry nodes to give the user parameters to play with (radius, height), even if the actual object in Blender is still a mesh.\n\n`Geometry Nodes` presets should be enough for now. After all, you can already generate those shapes in the `Geometry Nodes` already. What is important would be to have control, even if purely manual at import time, on how the Shape will be presented in Blender. For example, most users will want a Box to be defined with three parameters: `sizeX, sizeY, sizeZ`. However, depending of the physics engine you are dealing with, sometimes boxes are represented by two vectors: `bottom-left` and `top-right`. To match the Engine representation in the DCC, we'd need to be able to replace the default Geometry node by ours, where we'd expose the `bottom-left` / `top-right` vectors to the user.", "Implement drag and drop in ID text fields (ID name and/or paths)\nWindows 7 x64\n\nBroken: 705c43b\n\nwhen drag dropping images in the texture node's path field, it should replace the current texture name with the dragged and dropped one, but instead it does like if you dropped in empty space and adds a new texture node.\n\nOpen attached file, replace one of the windows with a file browser in a location where you have some images.

One of the issue with this is that it kind of conflicts with the same functionality on macOS which has system-wide option for the same functionality.\n\nThe idea to mitigate this confusion could be to introduce \"Auto\" display configuration. which will leave the final display transform to the OS.\n\nThere are some open topics with this proposal:\n\n- What should be the way of checking how render result would look like on a non-HDR screen: is it something to be done via the system-wide settings in the OS, or is it something to be done by adding/ensuring clamping the sRGB display OCIO configuration (possibly presented as a different display from the current sRGB)?\n\n- How to apply the \"Auto\" display transform on the saved images? Auto could be a boolean too.\n\n- Look at virtual displays as potential solution: 1082\n\n- Should Extended sRGB be its own colorspace, or a boolean toggle?\n\n### DCI-P3 display configuration\n\nThe title is kind of self-explanatory: there needs to be a configuration for the displays which use DCI-P3 color space.\n\nOne of the challenges is to preserve the Filmic View, which is currently designed for the sRGB screens. Arguably, it should be a look as it is often used for an artistic reasons. Nevertheless, this is a topic of investigation for the P3 display configuration.\n\n### ACES support\n\nACES is what a lot of studios and hardware manufactures are aligning up, and this configuration seems to be useful to have regardless of HDR story.\n\nAn argument for the ACES in the context of HDR is that it seems that it simplifies color grading process, ensuring that the final frame will look as close as possible to what artists had in mind as when viewed on various projectors and displays.\n\n## Draw manager & UI\n\nThere are following points which seems important for the decision making:\n\n- On macOS it seems to be very easy to provide window content in a specific color space (which is communicated to the NSWindow), and leave the display transform to the OS.\n- Blender needs to become usable on XYZ projects.\n\nThis leads to the following proposal: the entire Blender UI needs to become covered by color management of some sort. Possibly, render the whole Blender UI in wide enough color space (rec2020?). The final display color space transform is then either done by the OS, or as a window-wide shader.\n\n## Image IO\n\nFor images it is already possible to override display transform. So technically it is possible to apply proper tone mapping to make non-HDR image format look good.\n\nA possible life quality improvement could be to somehow streamline preview of the saved images. Currently it is kind of invisible, and the only way to know the final look is to open the file.\n\n## Video IO\n\nBlender uses FFmpeg, which seems to supports HDR. However, in Blender the integration is historically hard-coded to be 8 bit per channel.\n\nBoth FFmpeg reader and writer needs to ensure to support higher bit depths.\n\nFrom implementation details for the writer the interesting functions are `BKE_ffmpeg_append` and `BKE_ffmpeg_start` from `writeffmpeg.c` (this trickles up to the `bMovieHandle` abstraction used by the render pipeline). The frame API needs to be changed to accept `ImBuf` instead of `int*`, and the `IMB_colormanagement_imbuf_for_write` needs to be checked from a point of view that it does not enforces clamp.\n\n", "Viewport 3d is not updated with VSE driver\nBroken: 2.82 (unknown which revision, custom build without buildinfo)\nWorked: (unknown)\n\n[system-info.txt](system-info.txt)\n\nViewport is not updated for a material that is driven by a VSE driver.\n\n[ejemplo.zip](ejemplo.zip)\n\nChanging the VSE strip opacity doesn't update the viewport.\n\n**More info from user**\n\nI am creating an addon to transform eevee into a VSE.

This reduces and keeps control of memory usage for complex trees of any length. \nTrees with a few/simple operations may use a bit more memory than before as previous non-buffered operations are now buffered. \nCurrent focus is CPU, OpenCL is not available at the moment.\nPerformance will gradually improve as more operations are converted.\n\nBreaking changes from tiled system:\n- Translate, Rotate and Scale take effect immediately instead of next buffered operation.\n- Any sampling is always done over inputs instead of last buffered operation.\n\nKnown issues (will be fixed):\n- Scaling up, translating and rotating crops image.\n\nThere is an experimental option in master branch to enable it: \n- Go to Edit -> Preferences -> Experimental -> Enable \"Full Frame Compositor\"\n- Then go to Compositor -> Performance Panel -> Execution Model -> Tiled/FullFrame (Tiled is normal compositor)\n\n**Status and Work plan**\n* [x] [D11015: Compositor: Add vars and methods for easier image looping](D11015) \n* [x] [D11882: Compositor: Buffer iterators](D11882) \n* [x] [D11490: Compositor: Constant folding](D11490) \n* [x] [D11113: Compositor: Full-frame base system](D11113) \n* [ ] [D12750: Compositor: Support backdrop offset for the Viewer node](D12750) \n* [ ] Remove unused UI options: \"Chunksize\", \"OpenCL\", \"Buffer Groups\" and \"Two Pass\".\n* [ ] Convert operations to full-frame:\n * [x] Input nodes:\n * [x] [D11559: Compositor: Full frame Image node](D11559)\n * [x] [D11593: Compositor: Full frame RGB node](D11593)\n * [x] [D11594: Compositor: Full frame Value node](D11594)\n * [x] [D11690: Compositor: Full frame Render Layers node](D11690)\n * [x] [D11751: Compositor: Full frame Mask node](D11751)\n * [x] b1bf4c2a05\n * [x] 48e27ad122\n * [x] [D12090: Compositor: Full frame input nodes](D12090)\n * [x] Output nodes:\n * [x] [D11698: Compositor: Full frame Viewer node](D11698)\n * [x] [D11749: Compositor: Full frame Levels node](D11749)\n * [X] [D12091: Compositor: Full frame output nodes](D12091)\n * [x] Multilayer EXR output issue (#98475)\n * [x] Color nodes:\n * [x] [D11677: Compositor: Full frame Brightness node](D11677)\n * [x] [D11686: Compositor: Full frame Mix node](D11686)\n * [x] [D11764: Compositor: Full frame Color Balance node](D11764)\n * [x] [D11765: Compositor: Full frame Color Correction node](D11765)\n * [x] [D11766: Compositor: Full frame Exposure node](D11766)\n * [x] [D11767: Compositor: Full frame Gamma node](D11767)\n * [x] [D12093: Compositor: Full frame curve nodes](D12093) (RGB Curves and Hue Correct)\n * [x] [D12092: Compositor: Full frame color nodes](D12092)\n * [x] Converter nodes:\n * [x] [D11638: Compositor: Full frame ID Mask node](D11638)\n * [x] [D12095: Compositor: Full frame convert nodes](D12095)\n * [ ] Filter nodes:\n * [x] [D12167: Compositor: Full frame Bokeh Blur and Blur nodes](D12167)\n * [x] [D11634: Compositor: Full frame Bilateral Blur node](D11634)\n * [x] [D11694: Compositor: Full frame Sun Beams node](D11694)\n * [ ] [D11801: Compositor: Full frame Pixelate node](D11801)\n * [x] [D12219: Compositor: Full frame filter nodes](D12219)\n * [x] Vector nodes:\n * [x] [D12093: Compositor: Full frame curve nodes](D12093) (Vector Curves)\n * [x] [D12233: Compositor: Full frame vector nodes](D12233)\n * [x] Matte nodes:\n * [x] [D11627: Compositor: Full frame Box Mask node](D11627)\n * [x] [D11635: Compositor: Full frame Ellipse Mask node](D11635)\n * [x] [D11750: Compositor: Full frame Double Edge Mask node](D11750)\n * [x] [D12220: Compositor: Full frame matte nodes](D12220)\n * [x] Distort nodes:\n * [x] [D11944: Compositor: Full frame Scale node](D11944)\n * [x] 538f452ea9\n * [x] [D12165: Compositor: Full frame transform nodes](D12165)\n * [x] [D12166: Compositor: Full frame distort nodes](D12166)\n* [x] [D12466: Compositor: Add support for canvas compositing](D12466)\n* [ ] Fix tests affected by breaking changes.\n* [ ] #96406 Run operations in sync/parallel limiting the number of them to control memory usage.\n", "Rendering instability from Blender 3.5 to 36+\nOperating system: macOS 13.4.1\nGraphics card: Apple/AMD W6800X Duo\n\nBroken: 3.6 to 4.0\nWorked: 3.5.1\n\nI get substantial instability when rendering animation sequences in Blender 3.6 and above, compared to 3.5.

These are still modifiers and show up in the list as such, but they show a \"_Settings are inside the -context- tab_\". Not ideal.\n\n\n\nIn recent years, users have gained the ability to build their own modifiers using Geometry Nodes. This has led to incredibly complex modifiers featuring long lists of settings.\n\nThere has to be an easy way to list, and tweak modifiers.\n\n## The Solution\n\nLists.\n\nThis is not a new idea. Lists have been proposed several times with the oldest record I could find dating back to [this PDF from 2014 by Cole Reed](Modifier_Proposal.pdf). As well as [design tasks](38178), [RightClickSelect proposals](?sorting=hot), [community hacks](1106948247489257475), and [add-ons](1147752).\n\nThis was proposed over the years again, with the most recent being for Blender 3.0. The main reason against turning the modifier stack into a `UIList` widget is the loss of the [nice drag & drop](9b099c86123fc828a194c59ce5b8bbf5a56f9cdb) that was added back in 2020. With the new **List** widget this will no longer be an issue.\n\n## The List\n\nA list will contain all modifiers for the active object.\n\nAdding and removing modifiers will be done via the familiar `+` and `-` icons, same as in every other List in Blender.\n\nVisibility settings for each modifier will be icons on the right side. Dropdown items to `Apply`, `Apply as Shape Key`, and so on, will be in the dropdown button (under `+`/`-`). This dropdown could contain new operators that apply to the entire stack. Like `Apply All Modifiers`, `Delete All Modifiers` (some operations part of the popular **Modifier Tools** built-in add-on).\n\nModifier settings will still be inside a panel as it is currently, but the panel's header will be much simpler since visibility toggles are in the list now.\n\n\n\nThe `Particles` tab goes away. Particles Systems show up in the list of modifiers. When a Particle System is active, their settings will show up in a panel. All panels currently containing particle settings will be sub-panels.\n\nMost of the physics systems will show up in the modifiers list as well. With the exception of those that are not part of the modifier stack (**Force Fields** and **Rigid Body**). Each physics system will be a panel (just as it is currently).\n\n### Multiple Items\n\n_Optional. Just food for thought._\n\nOne modifier must be active, but several could be selected and displayed at the same time, to easily compare values or apply settings to multiple at once.\n\n\n\n## The Add Menu\n\nImplemented in !111717\n\n----\n\n\n\n\nThe current menu has issues:\n* Can't be searched\n* Too many items for accelerator keys to be useful (Mirror is one of the most popular modifiers yet it's not underlined)\n* Won't fit in small windows (an issue on all big dropdowns)\n* Categories are vague (is the Ocean modifier considered physics?, Mask modifier doesn't \"Generate\", it removes geometry)\n\nBut the main issue is that it can't be extended. Users could make their own modifiers and have them show up in the Add menu.\n\nSimilar to the `Add Object` or `Add Node` menus, a new list-style `Add Modifier` menu will look more familiar and be easier to navigate. With the upcoming [search in menus](110855) feature allowing to quickly find what we're looking for.\n\n\n(mockup using the current categories as example, this should be re-organized once the new system is in place)\n\nAt the bottom of the menu there will be our custom-made modifiers, grouped by catalogs, similar to how Node Group assets show up in the `Add Node` menu in Geometry Nodes.\n\nTo make adding modifiers faster, users can press `Shift+A` with the mouse over the properties editor to spawn the `Add Modifier` menu.\n\n## Conclusion\n\nAgain, this is not a new idea, but I believe Blender now has many of the pieces required to make this finally happen (the new Lists view, node/modifier panels, modifier assets).\n\nThis will make it easier to replace (and improve) the current modifiers with the help of the community, and make custom-made ones integrate seamlessly.\n\n## Plan of Action\n\nThis project will need a team. Some of the work can be done simultaneously by two devs, such as the `Add` menus is a separate project from the List display. A designer should be involved, and feedback from the community as always.\n\nObject modifiers would be the first to tackle but future work will be needed for bringing this (or similar) interface to:\n* Grease Pencil modifiers\n* Object constraints\n* Bone constraints\n* VSE modifiers\n* F-Curve modifiers\n\n## Related Tasks\n* [UI: Unify Add menus #111746](111746)\n* [Geometry Nodes: Extend add modifier menu with node group assets #111717](111717)\n* [User Interface: Re-design of Physics panel to unclutter interface and resembles Modifiers more #107326](111538)", "Solidify Node\nWe will drop support for Simple mode since the difference is hard to tell and performance-wise better to optimize the Complex mode than maintaining both.\n\nFill and Only options are a bit confusing in the modifier since fill refers to the fill of the rim and has to be checked on to make Rim Only work.\nInstead, I suggest making Fill refer to the part that is not the rim and Rim refer to the rim and make them independent from each other and both true by default.\n\nThe modifier has options for a vertex group as a factor for the thickness and two vertex groups to store the fill and rim geometry.\nvertex groups will be replaced by two attribute string fields for the factor and to tag the rim geometry\n\n", "Node groups' new method doesn't throw errors at inputs and outputs collections\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.38\n\nBroken: version: 3.1.0 Alpha\n\n\nNode groups' new method doesn't throw errors at inputs and outputs collections\n\n1.

That's because some data is accessed/modified that is not thread safe. E.g. `object_preview_render()` modifies `U.pixelsize`. I think other glitches are caused by overriding the active theme in `ED_view3d_draw_offscreen()` - although when I avoided this some time ago for similar work on threaded offscreen drawing for VR, this didn't solve the color flickering.\nThe active theme should probably use thread local storage.\n\nBesides that, the preview generation should be thread safe with OpenGL:\n* It uses the draw-manager's own context, which is mutex protected.\n* The non-thread-safe immediate mode API is not used inside the draw-manager.\n* The draw-manager already has workarounds for GPU driver issues with threaded drawing.\n\nA note: We could also speed up Eevee preview generation significantly by using viewport render quality, not final render quality.

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.

As viewport rendering and viewport playback are very tight related most changes will impact both of them and all changes should be tested to both use cases.\n\n## Approach\n\n### Phase 0: Preparation\n\n* Select several production scenes that will be used as benchmark (@Hjalti)\n** Scenes from different productions with different rigs and different sizes.\n* Modify blender to profile what is happening during animation playback. (@Jeroen-Bakker \n**Depedency Graph: Depedency Graph has a detailed profiler. Just need to check if it is sufficient.** Draw Manager: Draw manager already has a detailed profiler. We might want to add small changes (for example separate mesh_extraction from preparation) \n** Other: We should keep track of the rest of the time (not inside the Dependency graph/Draw manager) to detect balance shifts in performance\n* Create an automated test that records the timings in a database so we could compare the results and make decisions (@Jeroen-Bakker)\n* Document the hardware/OS's for the benchmark that will be used\n* Perform a base benchmark\n\n### Phase 1..n: Performance Cycle\nWhen doing performance test you do a single change at a time and monitor what that change does to the whole system. To make a change we suggest the next approach\n* Find the current weakest area\n* Do one or more prototypes to solve the weakest link\n* Select the solution.\n* Create design (mention the other solutions as alternatives) and implement the solution.\n* User test the chosen solution. (@Hjalti) \n* Codereview and merge to master.\n\nOnly after we complete a full cycle we can start with the next cycle. We continue this until we reached a workable performance or the year has ended.\n\n\n## Concerns\n\nThis approach tends to be too narrow focused when looking for solutions. When looking for solutions we should keep in mind to look at the whole picture and not limit the solution to the area in focus.\n\n## Known areas of improvement\n\nThis section contains a collection of known issues that we might want to tackle during the project\n\n* DrawManager mesh extraction uses a task pool per mesh. When two meshes needs to be updated for a frame it happens in serial.\n* Blender's task pool has been setup originally for long running background processes. It is currently used for tasks of all sizes.\n* Better select the frame ranges that needs to be updated for motion curves.\n* VSE/Graph editor dependencies. (ref play in active area)\n\n" ]

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "Show Emitter toggle still hides object after Particle System has been deleted.\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.67\n\nBroken: version: \n- 2.92.0 Alpha\n- 2.92.0 Alpha\nWorked: version: \n- 2.92.0 Alpha\n- 2.91.0 Release\n\nWhen you delete a particle system with show emitter unchecked under Viewport Display the object stays hidden.

But in typical painting workflows you'd expect to have this be a more universal toggle that affects all tools!\nToggling this per brush is not a reasonable solution.\n\nThere are multiple approaches to fix this.\n\n## Proposal: Alpha Auto-Masking\n\nThere is already a design in place for sculpt and paint mode. There we use auto-masking to easily target specific areas as a mode setting.\nThese are meant to be instantly accessible with a pie menu on `Alt + A` and would affect all tools and brushes.\nThis would likely be the most intuitive and fastest option.\n\n## Image Editor Inclusion\n\nIf we decide to replace the brush option with an auto-masking option this puts further pressure on implementing the same options for the image editor.\nThis might be reason enough to lower the priority for now, until the image editor can be properly prioritised to mirror the 3D viewport paint mode features.\n\n## Long Term Alternative\n\nOther image painting applications such as Krita implemented this as a toggle for any individual layer to paint on.\nWhile this is not likely to implement this way right now, it could be kept in mind for the UI of the [layered textures design]().", "Viewport Tools Settings panel appears after reload\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1650/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.79\n\nBroken: version: 2.92.0 Alpha\n- 2.92 - 2.8x\nWorked: Never\n\nI don't know, if this is intended.

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.", "Cycles - Viewport render preview stucked on the first sample - in a scene a DupliVerts objet parenting instances owned by more than one Groups\nBlender 2.78 (2.78 2016-10-24, Blender Foundation)\nMac Book Pro Retina 2013\n2.6 Ghz Intel Core i7 - 16GO 1600 MHz DDR3\nOSX 10.9.2\n\nUsing Cycles\n\nIn my scene with a parent DupliVerts object (Properties /Object / Duplication / Verts), with inside of if instances of Group.\nWhen those childs instances are from one group, that's ok.\nBut when they are from several groups, the 3D viewport render preview is stucked to the sample 1, rendered without ending !\n\nGood for heating the room ;)\n\nTo test, simply [Shift] - [x] in 3d the viewport in my blend to see this issue\nHope this help, keep the good work !\n[DupliVerts_and_Groups_BUG_with_Render_ViewPort_Cycles.blend](DupliVerts_and_Groups_BUG_with_Render_ViewPort_Cycles.blend)", "Eyedropper for props does not work in dialog boxes\nBlender 2.81, 71f2229b0d82\nfor example, in Texture Paint Context Menu\nI wanted to implement something using Operator and context.window_manager.invoke_props_dialog()\nThis is not a bug, but why not do it at the dialog level.\n", "Boolean - Animation - Viewport works correctly render view doesnt\nUbuntu 18.04, Win 7 x64\n\nBroken: d53093953f8\n\nBooleans dont match between Viewport and Render\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.", "UV Editor has no 'View Overlay' Theme option\nOperating system: macOS-12.0.1-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 575 OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.7.29\n\nBroken: version: 3.0.0\nBroken: 2.90, 2.91, 2.92, 2.93, 3.0 used something else (black in my case)\nWorked: 2.83\n\nThe UV Editor theme does not have a `View Overlay` option.

The first image shows a cube with a color attribute added. The geometry nodes setup adds a red color to the \"Color\" attribute. This all works as expected as can be seen in the viewport and the spreadsheet. \n\n\n\nIf a GN cube is added instead of the standard mesh cube (which has been bypassed by the switch node) then the color attribute is added as expected. This can be seen in the spreadsheet as to be the same as the previous screenshot for the color attribute. However, it is not being displayed in the viewport.\n\n\n\nThis is a problem seen with any procedural geometry made with just nodes. As a workaround, you can have a single vertex as the only \"real\" geometry and use a join node to join with any nodal procedural geometry. Strangely though, this has to be the first connection in the join node, and won't work if it is second. This can be seen by the next 2 images:\n\n\n\n\n\nA similar related case is that some mesh nodes will also make the viewport lose the displayed attribute. For instance, if you create a cube, add a GN modifier and add a dual mesh node to the chain, the color attribute is still there, but no longer displayed in the viewport. This happens with some nodes (like mesh to volume and back to mesh) but not others (like subdivide or extrude).\n\n\n\nThere is also a related issue that when exporting to obj or gltf the color attributes are not exported if they are not displayed in the viewport. If apply the GN modfier, you have to actually click on the color attribute in the properties panel to see it in the viewport or to be able to export it. \n\nOddly, the fbx exporter seems fine without applying the modifier. It also doesn't matter if the color attribute is on the vertices, or face corners, or if the color is float or byte color. The same issues happen regardless.\n\n", "NaN pixels in Normal Pass\nOperating system: Linux-3.10.0-1127.10.1.el7.x86_64-x86_64-with-centos-7.8.2003-Core 64 Bits\nGraphics card: GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 440.64\n\nBroken: version: 2.83.0\nWorked: (Unknown)\n\nI produced a template based rendering solution and am experiencing occasion nan pixels in the normal pass output.

I was running a custom built 2.72 from several weeks ago, and I was having trouble with transparency that wasn't a problem in the stock Ubuntu 2.69 package. When I saw that there was a recent commit related to this, I downloaded and built 2.73 to see if it fixed the issue. It did not.\n\nI've attached a file which hopefully demonstrates the problem. It's simply a solid cube inside another cube, with the inner cube having an opaque materials and outer cube material set for alpha blend transparency (green glass). Sometimes it renders as expected, and sometimes it does not. The incorrect result is that the inner object does not show through the transparent glass outer object, even when the background does. If you remove one face of the outer cube, the effect is more obvious, with part of inner cube being rendered, and part of it not (as if the outer cube were opaque even though it isn't.

[ "Vertex groups with identical names can exist, and when they do, a lot of things break.\nRenaming a bone of an armature also renames the matching vertex group of linked objects/obdata, if found.\n\nCurrently there is no check made for potential collisions in vgroups names, which can lead to two or more vgroups having the exact same name, which is considered as invalid data.\n\nThis could be solved in several ways:\n- Rename the existing/clashing vertex group *(and make sure all usages elsewhere are updated along)*\n- Change the specified bone name to be unique in a way that it does not conflict with any existing vertex group name.\n- Merge the (renamed) vertex group with the already existing one with that new name.\n- Refuse to rename the bone in case it would conflict with another existing vgroup name.\n\n--------------------------\n\n*Original Report*\n\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71\n\nBroken: version: 2.93.5\nBroken: version: 2.83.0\nDidn't test earlier than that (thought 2.79 is too different to matter); didn't test intervening versions; 2.83.0 is just the oldest version since 2.80 that got saved in my Blender folder.\n\nRenaming bones in an armature renames vertex groups of child mesh objects without dealing with name collision. When that happens, a lot (most?) functions involving vertex group weights no longer work correctly-- it appears that they assume vertex group names are unique identifiers.\n\n1) Make a monkey. Give it a vertex group. It's named \"Group\".\n2) Create an armature. Parent the monkey to the armature with automatic weights. Monkey now has VGs \"Group\" and \"Bone\".\n3) Enter edit on the armature. In properties/bone/name, change the name of Bone to \"Group\".\n\nMonkey now has 2 VGs named \"Group\".\n\nAnd, when they get created, stuff breaks. I consider the real bug here to be, \"Vertex groups can acquire identical names\", but one could also consider the bug to be, \"Multiple operations assume VG names to be unique identifiers when they are not necessarily unique.\"\n\n\n\nHere's a quick screenshot of a bugged mesh (not one that I made.) Notice the sidebar list of vertex groups: we've got three different duplicated vertex groups in that list, by my count.\n\nWhat breaks when this happens? The first obvious thing, apparent from the screenshot, is interpolation of vertex groups from a subdivision modifier. We can see that the selected vertex group is no longer interpolating smoothly between verts.\n\nWhat else breaks? A \"normalize all\" operation no longer actually normalizes all vertex groups properly. Post normalization, these don't add up to 1:\n\n\n\nI'm sure that there are other operations that would stop working as well-- those are just the quickies that I noticed. If subdivision interpolation doesn't work right, I wouldn't expect poke faces interpolation or inset faces interpolation to work any better, for example. But I haven't tested all that.\n\nI'd consider this a really low priority bug. The problem doesn't actually show up that often (I'd estimate five times in five years for me.) And it's reasonably easy to work around, provided you're willing to throw your weights away-- you just delete all groups and start again. If unwilling to delete all groups, you can probably get what you want with some math on the VGs (with a VG mix modifier or with geo nodes) and then delete only the problem groups.\n\nUnfortunately, the one big problem with this bug is that it's not very apparent when it happens, which can lead to extra wasted work.", "Blender is crashing instantly to the desktop randomly (solid viewport)\n\nOS: Windows 10 Pro 64bit (Version 21H2, OS Build 19044.2006)\nGPU: Nvidia GeForce RTX 2070 (Driver: Version 517.48 (released 27th September 2022))\nCPU: AMD Ryzen 7 2700\nRAM: 64GB\n\n\nBroken: version: 3.3 (and versions for the last couple of years)\nWorked: none since 2020 approx.\n\n\nBlender crashes seemingly randomly when performing modelling actions such as moving vertices, clicking sliders or buttons, switching to wireframe view, or moving the viewport camera in any way.

When adding attributes to these meshes in the `frame_change_pre` handler, Blender can crash during render on random frames.\n\nThe `Render → Lock Interface` option is enabled as per the note in the [handlers documentation ](bpy.app.handlers.html#note-on-altering-data).\n\nI have created a simplified script that reproduces this crash during render, typically within a minute of starting the render. This script randomly generates triangles and attribute values in a frame change handler:\n\n```lines=5\nimport bpy, random\n\n\ndef frame_change_pre(scene):\n n_triangles = 10000 # number of triangles to generate\n n_attributes = 10 # number of attribute 'layers' to generate\n \n tsize = 0.1\n vertices = []\n triangles = []\n for i in range(n_triangles):\n xshift, yshift, zshift = random.uniform(-3, 3), random.uniform(-3, 3), random.uniform(-3, 3)\n vertices.append((-tsize + xshift, -tsize + yshift, zshift))\n vertices.append((tsize + xshift, -tsize + yshift, zshift))\n vertices.append((0 + xshift, tsize + yshift, zshift))\n triangles.append((3 * i, 3 * i + 1, 3 * i + 2))\n\n object = bpy.data.objects[\"Cube\"]\n object.data.clear_geometry()\n object.data.from_pydata(vertices, [], triangles)\n \n for i in range(n_attributes):\n attribute_name = str(i)\n try:\n object.data.attributes.remove(object.data.attributes.get(attribute_name))\n except:\n pass\n \n attribute = object.data.attributes.new(attribute_name, \"FLOAT\", \"POINT\")\n for value in attribute.data:\n value.value = random.uniform(0, 1)\n \n \nbpy.app.handlers.frame_change_pre.append(frame_change_pre)\n```\n\nIncreasing the number of triangles and/or number of attribute layers seems to increase the frequency of crashes. The crashes do not seem to occur when rendering from the command line.\n\nThis is the error reported after the crash:\n\n```\nError : EXCEPTION_ACCESS_VIOLATION\nAddress : 0x00007FF7736C6490\nModule : blender.exe\nThread : 00000814\n```\n\nAttached is the crash log: [attribute_crash_example.crash.txt](attribute_crash_example.crash.txt)\n\n\nAttached is a .blend file including the script that reproduces this issue.\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.", "Cycles Regression: Changing \"Start Samples\" in denoiser resets viewport render\nOperating system: Linux-5.14.0-3-amd64-x86_64-with-glibc2.32 64 Bits\nGraphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 495.29.05\n\nBroken version: 3.0.0 Alpha\nWorked: Prior to Cycles-X merge\n\nChanging the `Start Samples` value for the viewport denoiser resets the viewport rendering.

This should really be made consistent across both modes. \n\n\n", "Paint Mode: Color Fill Tools\nNOTE: This design is still under discussion and is incomplete.\n\n# Issue\n\nCurrently there are different implementations of filling a solid color while in a mode:\n- Fill Tool (Texture Painting)\n- Fill operator (Vertex Paint Mode)\n- Color Filter (Sculpt Mode)\n\nThis needs to be reworked for consistency and to ensure more convenient and efficient workflows.\n\n# Requirements\n\nThere are certain broader features that will be required, no matter how the design of color filling looks like:\n- Fill everything that is not masked\n- Gradual Fill (Not full strength)\n- Fill via gestures (Box, Lasso, Line, Polyline)\n- Fill entire UV-islands, mesh-islands, face sets\n- Fill faces instead of pixels\n\nThere is also the common use of gradients and expand. This should be further notes down in #99770.\n\n# Goal\n\n### Key Problem\n\nThere are many different ways to give all of these tools to the user.\nWhat we should avoid is to have a large set of tools or tool settings scattered throughout the UI.\nThis is already an observable problem with the existing gesture and filter tools in sculpt mode:\n- None of the tools have shortcuts\n- Picking the tool, tool-type and adjusting the settings is time consuming\n- Each tool has their own disconnected settings\n\n### Conclusion\nWe should aim for a more systematic approach.\nAll of the requirements need to be easy to understand and access.\nThat is easier to accomplish if there are fewer tools that are not specifically just for a single purpose.\n\n# Proposal\n\nInstead of adding a lot of new tools/brushes and settings for filling in colors, we can rely on the current and planned masking features.\n\n### Mask -> Fill\n\nFilling should be as instant as possible. But first you need to define what to fill.\nBlender often has a strong design of \"Selecting -> Operation\". By strengthening the masking features via #97955 we could rely on this for color filling operations too.\n\n### Fill Operator\n\nThe most important part as a baseline is a simple operator that immediately fills in everything that is unmasked.\nCurrently this is implemented in Vertex Paint Mode with the shortcut `Shift + K`.\nThis could get a more convenient shortcut on the left of the keyboard.\n\nIt needs to be always clear what color will be used for the operator.\nThe easiest answer would be the primary color of the currently used tool/brush.\nIf the current brush/tool doesn’t have a primary color, then the primary color of the scene color should be used.\nIn that case it becomes very important that this color is somehow exposed. Otherwise there will be too much unnecessary switching between masking and painting tools.\n\n### Auto-Masking\n\nThis way of targeting specific areas is useful for any brush or tool. It already proved itself essential in Sculpt Mode.\nThe aim should be to use auto-masking for the fill operator as well.\n\nIt will be vital to add auto-masking support to the image editor for painting. Topology auto-masking in this case could mask UV islands instead.\n\nOpen question:\n- Is a “UV-island” auto-masking in the 3D Viewport needed or is it more convenient to initialise face sets from UV seams?\nThis could save us space in the auto-masking pie menu.\n\n### Masking Modes\n\nWe also need to allow filling by faces instead of pixels.\n\nWe are already aiming to implement three masking modes in Paint Mode (#97955) and an inverted masking approach (#97903) that could also cover this use case.\nWith this feature it would be as easy as pressing `2` on the keyboard and using any masking tool/operator to mask faces.\nThe fill operator can then fill all unmasked areas, or they can be painted in more detail with any painting tool.\n\n### Gradual Filling\n\nFor this the Color Filter, fill type should still be used. \nBut the fill operator could also get a strength input in the adjust last operation panel.\n", "Select Interior Faces causes assertion failure with zero-area faces in certain situations\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\n\nBroken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-23 17:19 , hash: `8f4d991594`\nWorked: Unsure\n\nA specific mesh, which includes a zero-area face, causes an assertion failure when running the *Select All By Trait > Interior Faces* operator\n\n1.

This in itself it to be expected and not really a problem though it might be nice to prevent. When you bevel with the bevel operator the same happens. The problem is that the bevel modifier causes a recalculation of all normals, which generates random normals for the zero area faces. These random normals lead to strong shading artifacts when the shading is set to shade smooth.\n\noriginal report follows:\n----------------------------------------\n\n\n\n\n\n\nInconsistent normal behaviour when using a bevel modifier with\n(a) amount exactly matching the face dimension (or is clamped), and\n(b) auto smooth off\nWhen compared with auto smooth on, or just bevelling an edge directly.\n\nIn the sample file attached, I've created an L shape by creating a plane, then extruding 3 additional edges.\nI've added a reflective material to see how the normal affects the reflections.\nFor each L shape, I've then added a bevel modifier, only changing amount/segments. Or alternatively I've done bevel edge, and only set amount/segments.\nThen I've either set to smooth or flat shading, and/or turned-on auto-smooth.\n\nIn the attached file, I've prepared the different test scenarios.\nFrom bottom to top:\n - Modifier/Flat,\n - Modifier/Smooth, // This is the row where I see inconsistencies (highlighted in red)\n - Modifier/Smooth/AutoSmooth,\n - BevelEdge/Flat,\n - BevelEdge/Smooth,\n - BevelEdge/Smooth/AutoSmooth,\n\nFrom left to right:\n - Amount=2, Segments=10, // obvious difference for the flat plane above the bevel, plus weird anomaly for top segment of bevel\n - Amount=2, Segments=3, // obvious difference for the flat plane above the bevel\n # Amount=1, Segments=3, // this row has no apparent differences\n\n\n\nWhen viewing the file, I find it best to use material preview mode, then orbit up/down, and compare the reflections of the different rows.\n\n\nMy analysis.\nWhen performing a bevel, the faces being bevelled shrink to make space for the bevel, but retain their original normal.\n \n\nWhen the bevel amount matches the face size, then those faces still exist, however they have zero size - represented by the red lines.\n\n\nUsing the spreadsheet in 2.93, I can see inconsistencies with the normal vector for these faces.\n\nHere I've set the bevel modifier segments=1, and amount=2.\n\n\nAnd the corresponding spreadsheet (annotated).\n\n\nYou'll note that the two empty faces do have valid unit normals, though both a pointing at Z=1.\nYou would expect the vertical face - [x] to have a normal with X=1.\n\nHowever if you compare with the reference scenarios like having auto-smooth=on, or applying a bevel edge directly, this is what you see.\n\n\nIn this case, rows 0 and 4 actually have the normal vector set to 0, 0, 0. (I.e. technically an invalid unit vector.)\n\n\nSo, what I believe is happening is that when there is an invalid normal vector, then blender refuses to perform smoothing across from one face to another. The smoothing ends at the bevel edge and the adjacent face in this case is shaded flat.\n\nGetting back to the bevel modifier when auto-smooth is off, while this has valid unit vectors, one of those vectors has the wrong orientation.\nThis is why there is a reflection anomaly on the vertical face, but not on the horizontal face.\n", "Data Transfer modifier works only for Byte Color & Face Corner color attributes\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3060 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12\n\nBroken: version: 3.2.0\n\nIf a target color attribute Domain is *Vertex* or it's Data Type is *Color*, the data are not transferred.\n\n[data-transfer-color-attr-bug.blend](data-transfer-color-attr-bug.blend)\nYou can see in the attached .blend that the Data Transfer modifier is set correctly, but the Col attribute isn't updated.\nAfter doing Convert Attribute -> Domain: *Face Corner*, Data Type: *Byte Color*, it starts to work correctly.\n\n\n" ]

However, this one particular piece in my scene has been causing endless trouble for me despite being the exact same procedure.

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)", "Vertex Paint Viewport Overlays stencil mask not working\nplatform: Windows-10-10.0.19042-SP0\nGraphics card: 1080\n\nBroken: 3.1.0 Alpha \n```\n commit date: 2021-11-14 00:26 hash: 7e82c840b7a4\n build date: 2021-11-15, 00:51:48\n```\n\nWorked: Has'nt worked for ages\n\nGo to vertex paint mode, select some polys on a model.\nGo to overlay options/vertexpaint/stencil mask opacity the slider does nothing to unselected polys overlay.\n\n\n\n\n", "Extrude manifold on multiple non-adjacent faces gives wrong results\nOperating system: Darwin-19.5.0-x86_64-i386-64bit 64 Bits\nGraphics card: AMD Radeon Pro 5500M OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.9.15\n\nBroken: version: 2.90.0 Alpha\nWorked: never\n\nWhen using extrude manifold when multiple non-adjacent faces are selected, you sometimes get some weird and inconsistent results with missing edges.\n\nDefault cube -> edit mode\nAdd one loop cut\nSelect two opposing faces next to the loop cut\nTransform orientation: normal, pivot individual origins\nExtrude inwards\nResult: ngons on both sides with missing edges where they should be.

Including all of these in their current form in a single Paint Mode would lead to a muddled and confusing design.\nBut still, these ways of masking should be supported:\n\n- Masking per vertex (Like Sculpt Mode masking)\n- Masking per face (To achieve sharp edges on face corner color attributes and image textures)\n- Masking based on selection (Synched with edit mode)\n- Masking based on a texture (Stencil Mask)\n\n# Issue\n\nThese ways of masking are very different and currently implemented as completely separate features.\nMoving all of these with their current design to a new Paint Mode would lead to multiple masks and selections having to be enabled and managed at the same time, each with their own overlay.\nThis issue can already be observed in the current Texture Paint Mode when enabling any of the selection masking modes and stencil masking at the same time.\n\nThe ideal way moving forward in Paint Mode has to be by combining these masking methods into a single cohesive design without regression in functionality.\n\n# Proposal\n\n### Masking Modes\n\nThe proposal is to add three easily accessible “Masking modes” to choose which data is being used for the masking operations in Paint Mode.\nThese should be easy to switch between via the number keys. \nThis directly parallels the selection modes in edit mode, grease pencil and the UV editor. And just like in these other modes they should be interchangeably usable for intuitive and fast masking.\n\n\n\nThe 3 modes would let you:\n\n- **Mask Vertices** (Vertex float)\nSame behaviour as sculpt mode.\n\n- **Mask Faces** (Face bool)\nWill restrict the masking to only fill in entire faces as completely masked or unmasked. This is far more useful than trying to paint face float values, which will almost always result in a stepping effect.\n\n- **Mask Pixels** (Greyscale image texture))\nThis feature should replace the current “Stencil Mask”.\n\n### Converting Masks\n\nThese masking features are meant for loose and temporary masks, similar to selections in other modes. \nFor more permanent masking for material and texture mixing it would still be preferred to paint image textures and use them as masks in the material.\n\nWith that use case in mind, it would be easiest to implement to convert the mask to another domain and data type every time the masking mode is changed (Similar to selection modes in Edit Mode).\n\nAlternatively we could test a way of abstracting/propagating the selection between those modes but that could just end up as far more complicated, less predictable and for questionable advantages.\n\n### Edit Mode Syncing\n\nAn important task that is tied to this is to convert the mask of Paint Mode to the Edit Mode selection (and vise versa).\nThis way masks can be much more precisely created in Edit Mode.\nWhile switching between Edit Mode should not be required - masking in Paint Mode should be intuitive enough for most cases - some workflows rely on this for painting precise attributes and technical textures.\n\nSo keeping this functionality will be a priority!\n\n(There are even other potential advantages from considering a Paint Mode mask an Edit Mode selection, like assigning materials directly in Paint Mode. \nThe design of #97903 could help in making this more clear.\n\n# Sculpt Mode\n\nIf these masking modes should be included in Sculpt Mode as well is questionable. \nMasking faces and based on an image texture is no use if you are only able to affect vertices with all tools available.\nThe only advantage would be to avoid mask conversion on mode switching (Which shouldn't be a problem) and to allow painting face corner color attributes with the Sculpt Mode painting toolset (Which is not what Sculpt Mode is for. For sharper edges you should increase the amount of geometry or use the bigger Toolset of Paint Mode)." ]

This triggers the above conditional that sets `p->pressure` to `1.0f` (full pressure), causing the issue.\n\nIn the attached .blend file:\nUsing a pressure sensitive drawing tablet, lightly use the Grease Pencil eraser tool to erase the strokes, then release your stylus.\n(If your drawing tablet sends an event with a pressure value lighter than `0.001`, the issue will occur)\n\n## Question: Is #47101 still relevant and applicable?\nI'm not sure I fully understand the use-case that was effected by #47101 or whether it is even still applicable to Blender today, 8 years later.\nIf someone can shed some light on what the intended behavior of 74f291cdea979 is and whether it is still needed, I will happily work on a pull request to reconcile this issue (or simply remove the conditional if it is no longer applicable)\n\n" ]

(reported in comment)\n\nBooleans can often be very touchy and may require positioning them just right for them to do operations properly. 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)", "Weight paint vertex select difficult to see (depends on surface color)\nThis is

Its like reflection always fades to top and increasing trace precision doest fix it.\nNormally trace precision allows for reflections go all the way up on (for example cube surface) to make its surface fully reflected, but new 2.93 Trace precision 1 doesnt allow for fully making surface reflective and give darker less reflective areas near upper side edges or upper corners\n\nFor instance, in most cases: 2.92' SSR with trace precision 0.25 is almost = (almost equal to ) = 2.93 SSR with trace precision 1 (maxed)\n\n(Even though camera is further away enough to get all the reflections from screenspace , new SSRI 2.93 trace precision is inadequate and kind of gives the effect of ''as if'' we make zoom in so screenspace doesnt see all objects and the top part of cube didnt get any reflections and get darker and faded into weak reflections) \n\nMoreover, when its compared with cycles, with trace precision of 1 ob both , 2.92 one looks closer to cycles while 2.93 has faded reflection on upper pars of surface (maybe even though new reflection implementation uses cycles implementation, new implementations inadequate trace precision might be making it differerent from cycles)\n\n\n1. Create a plane scale by 5 and move -1 (down)\n2. Edit the material of default cube and previously created plane by using same material and give it a red color FF0000 with max saturation 1 \n3. Optional step: make base color saturation of material lower to see faded darkening effect more Plus Make it metallic if you want to see the result more with metallic or just leave it as it is\n4. Ensure viewport shading settings do not use scene world but use the forest HDRI and maximize world opacity and remove blur\n5. In properties rendering tab, Enable screenspace reflections and make edge fading zero. Also uncheck half-res trace\n6. Go camera view and dont zoom too much on viewport so screenspace reflection can see everything around\n7. !!Do same processes in 2.92 and 2.93 releases to compare \n8. Then, set 2.92 and 2.93 have trace precision to 0.25 - and observe\n- In 2.93 U will notice the reflected surface of the cube as u approach top edges/as u go up, have darker/unsaturated or ''Faded'' screenspace reflections caused by the trace preciison is not enough to reach there\n- however in 2.92, the reflection reaches better to all the surface and it has almost no faded or darker look\n9. Make 2.93 SSR trace precision 1 while 2.92 SSR is still 0.25 and observe:\n- then u will notice, ''the result of 2.93 SSR Trace precision 1 '' is more similar to ''2.92 SSR with trace precision of 0.25 ''\n10. When 2.93 SSR Trace precision is 1, make 2.92 SSR trace precision 1 and observe agan\n- Then u will notice 2.92 SSR Trace precision is the ideal to fully trace all reflection to surface perfectly without having any faded area with less reflection. On the other hand, 2.93 Trace precision 1 is still not adequate to put reflection to upper parts of cubes surface near top edges with full power and precision\n\n'!! Compare these on both 2.93 and older 2.92 version with old SSR implementation\n\nIn summary in 2.92 when we increase trace precision from 0 to 1, the tracing or visibility of reflections go all the way up to top edge of cubes surface making it fully reflected as trace precision maxed\nOn the other hand, in 2.93 if we increase trace precision from 0 to 1, the reflections still cannot reach all the way up to cubes surface near top edge which gives a faded and partially traced upper surface area.\n\nMaybe, To solve this maybe, the screenspace trace precision factor can be multiplied by 4-6 or maybe the it should be square cubed so the 2.93 trace precision of 2.92.\n\n[2.93&92 SSR-TRACE PRECISION 1 - CAMERA VIEW .blend](2.93_92_SSR-TRACE_PRECISION_1__-_CAMERA_VIEW_.blend)\n\n[2.93&92 SSR-TRACE PRECISION 0.25 - VIEWPORT VIEW POSITIONED .blend](2.93_92_SSR-TRACE_PRECISION_0.25_-_VIEWPORT_VIEW_POSITIONED_.blend)\n\n[2.93&92 SSR-TRACE PRECISION 1 - VIEWPORT VIEW POSITIONED .blend](2.93_92_SSR-TRACE_PRECISION_1_-_VIEWPORT_VIEW_POSITIONED_.blend)\n\n[2.93&92 SSR-TRACE PRECISION 0.25 - CAMERA VIEW.blend](2.93_92_SSR-TRACE_PRECISION_0.25__-_CAMERA_VIEW.blend)", "Viewport rendering bug : unable to make the render progress (infinite calculation)\nOperating system: Windows 11\nGraphics card: RTX 3090\n\n**3.0.1**\n\nI installed the latest studio drivers for the graphic card (28 january 2022 version), and then :\n\nI encounter a really strange bug when using the viewport rendering (with or without denoising) on some projects.

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", "Crashes when Switching to Material Viewport / Rendered Viewport / Rendering\nOperating system: Windows 10\nGraphics card: 2 Nvidia GTX 1660 Super's\n\n[blender_system_info.txt](blender_system_info.txt)\n\nBroken: blender 2.8 / 3.4\n\n\nBlender runs completely fine when editing and building a model but once rendering is involved, even in preview, it immediately closes with no explanation.

For example, not everybody uses modifiers, so having a column of buttons to disable modifiers can be useless.\n- - [ ] Replace box-select with click-drag (like buttons). This will give more immediate feedback of which channels are selected, rather than seeing that feedback only when releasing the mouse.\n- - [ ] Auto-scroll the list back into view when all the list entries are outside the view (happens when changing selections)\n- - [ ] Auto-scroll the channel list when drag-selecting.\n\n\nVisual changes:\n\n- - [x] Separate the eye toggle from the Graph Editor curve color indicator ([D5882](D5882))\n- - [ ] Use alternating lines (see Outliner)\n- - [ ] Highlighted row should use solid colored background (see Outliner)\n- - [ ] Rolling over rows should highlight them (see Outliner)", "Crash without warning when opening material properties panel.\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: AMD Radeon RX 540 Series, ATI Technologies Inc., OpenGL, 4.5.0 Core Profile Context 22.20.16.03.220829\n\nBroken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: 55485cb379f7\nBroken: version: 3.5.1, branch: blender-v3.5-release, commit date: 2023-04-24 18:11, hash: e1ccd9d4a1d3\nWorked: no newer version works.\n\nWe get a hard crash without warning when opening the material properties panel in the \"Layout\" workspace right after startup (i.e. with a clean \"General\" new file).

This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. 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.

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", "Dynamic paint sub-steps don't work when the brush position is set in geometry nodes\n\nI believe this **may** be the same issue as T40597\n\nIn order to have a brush follow a potentially very large collection of curves in sequence, I'm using geometry nodes to set the position, which avoids the pain of having to join the curve paths or painstakingly tweak the offsets and influence keyframes for each and every one.\n\nThis works, but with sub-steps enabled it seems that the nodes are still only being updated once/frame. Or, if they are being updated, then the `seconds` input from the `Scene Time` node is being derived from the `frames` value which is clamped to an integer.\n\n\n[text_path_test.blend](text_path_test.blend)\n", "Modifiers don't work on particle instances of a hidden object\nOperating system: Linux Mint 20.3 Cinnamon kernel 5.13.0-35\nGraphics card: 3400G\n\nBroken: 2.83\nWorking: apparently never\n\nRelated to #96367 (Crash when trying to snap to instances on an object)\nTo replicate bug, the instantiated Object (the one with a `Modifier`) has to meet the following conditions:\n* Must have a modifier (obviously)\n* Must be instantiated through a particle system.

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", "Bug with inconsistency combining workspaces and main windows (it happens in ALL BLENDER VERSIONS)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71\n\nBroken: version: 3.0.0\n\nWhen working with more than 1 main window of the same Blender project, if new workspaces (Layout, Sculpting, Scripting) are added in one window, they are not properly displayed on the other.

When adding attributes to these meshes in the `frame_change_pre` handler, Blender can crash during render on random frames.\n\nThe `Render → Lock Interface` option is enabled as per the note in the [handlers documentation ](bpy.app.handlers.html#note-on-altering-data).\n\nI have created a simplified script that reproduces this crash during render, typically within a minute of starting the render. This script randomly generates triangles and attribute values in a frame change handler:\n\n```lines=5\nimport bpy, random\n\n\ndef frame_change_pre(scene):\n n_triangles = 10000 # number of triangles to generate\n n_attributes = 10 # number of attribute 'layers' to generate\n \n tsize = 0.1\n vertices = []\n triangles = []\n for i in range(n_triangles):\n xshift, yshift, zshift = random.uniform(-3, 3), random.uniform(-3, 3), random.uniform(-3, 3)\n vertices.append((-tsize + xshift, -tsize + yshift, zshift))\n vertices.append((tsize + xshift, -tsize + yshift, zshift))\n vertices.append((0 + xshift, tsize + yshift, zshift))\n triangles.append((3 * i, 3 * i + 1, 3 * i + 2))\n\n object = bpy.data.objects[\"Cube\"]\n object.data.clear_geometry()\n object.data.from_pydata(vertices, [], triangles)\n \n for i in range(n_attributes):\n attribute_name = str(i)\n try:\n object.data.attributes.remove(object.data.attributes.get(attribute_name))\n except:\n pass\n \n attribute = object.data.attributes.new(attribute_name, \"FLOAT\", \"POINT\")\n for value in attribute.data:\n value.value = random.uniform(0, 1)\n \n \nbpy.app.handlers.frame_change_pre.append(frame_change_pre)\n```\n\nIncreasing the number of triangles and/or number of attribute layers seems to increase the frequency of crashes. The crashes do not seem to occur when rendering from the command line.\n\nThis is the error reported after the crash:\n\n```\nError : EXCEPTION_ACCESS_VIOLATION\nAddress : 0x00007FF7736C6490\nModule : blender.exe\nThread : 00000814\n```\n\nAttached is the crash log: [attribute_crash_example.crash.txt](attribute_crash_example.crash.txt)\n\n\nAttached is a .blend file including the script that reproduces this issue.\n\n1.

Our current Character Spacing is already done strangely enough. This value is divided by 2 then 0.5f is subtracted from it. That value is a portion of the font's em square that is added to each character. So a value of **1 means no change** to character spacing. 0 means that 0.5 of an em is subtracted from each one. That \"1\" means default is bad enough, but much worse to show it as one meter. \n\nAt minimum we should show this as unitless. Better would be to not do the division and shifting and therefore show \"0\" as default and add \"em\" as unit. This would match with CSS letter-spacing.\n\nWord spacing is similar, but is a factor multiplied against each character's advance. So again, \"1\" means normal, 0 means that a space has no width, a 2 means a space is twice as wide. No relation to grid size. So showing \"1 meter\" is pretty bad.\n\nThis also should be unitless.

[ "Python API support for element picking (matching selection picking)\nCurrently there is no convenient way to pick the object under the mouse cursor.\n\n### Motivation\n\nPicking an item (typically an object), under the cursor is useful for interactive tools,\nfor selecting a target... etc. as is already done in Blender's C code.\n\nCurrently methods of doing this are insufficient.\n\n- Ray-cast only works for mesh, geometry types and isn't useful for mesh elements, bones... etc.\n- Selection picking changes the selection, is awkward to access the result and doesn't allow to filter elements (if you only want certain object types for example).\n\nThis limits the kinds of interactive tools that can be written (at least easily).\n\n### Proposal\n\nFor space types that support picking elements, add a method for picking items, example usage:\n\n```\nlocation = event.mouse_region_x, event.mouse_region_y\nob = context.region.find_on_screen_object(location)\n```\n\nSince it's common to filter items based on type, or other properties, a filter function should be supported.\n\n```\nob = context.region.find_on_screen_object(location, filter=lambda ob: ob.type == 'GPENCIL')\n```\n\nBMesh elements could be supported too.\n\n\nNote that returning multiple values is needed in some cases if the element on it's own doesn't provide enough information. For example, a bone or vertex doesn't give access to the object, which is needed for multi-edit mode support.\n\n```\nresult = context.region.find_on_screen_mesh_edge(\n location,\n filter=lambda candidate: candidate.object.get(\"my_property\") == 1 and candidate.vert.co.x > 1.0,\n)\nif result:\n print(result.object, result.vert)\n```\n\nOther space types can support this too.\n\n```\nnode = context.region.find_on_screen_node(location, filter=lambda node: node.type != 'OUTPUT_MATERIAL')\n```\n\n\n### Open Topics\n\n- Would we support a returning multiple hits (callers might be able to use the filter function for this if they really wanted).\n- Should this be a generic function for all types of objects:\n\n```\nTypes could be passed in as an argument. e.g.\n```\n\n```\n`context.region.find_on_screen_item(location, type={'EDIT_MESH_EDGE', 'EDIT_MESH_FACE'})`\n```\n\n- Why limit this to picking? 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?

You select what you can see. If user wants to box/circle/lasso select something on the other side of a mesh, they'd either turn on X-Ray or move the camera until it's visible. With objects Blender always selects through, and it can't be turned off. Give user control over this, and provide some convenience features. \n\nMake a popover for the X-Ray button. Move the X-Ray settings here from the Shading Popover. Give them new names so it's more clear that wireframe and solid have separate X-Ray properties.\n\nIf user wants to box/circle/lasso select unseen mesh without X-Ray, they can use Select Through. 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" ]

This means that we don't have direct control over the F(0) reflectivity of the dielectric parts of the mesh, which is why Blenders Principled BSDF additionally also has a specular parameter to control the F(0) reflectivity of these areas.\nSince with metallic materials the F(0) reflectivity is directly controlled by the Base color this means that for metallic areas the specular parameter should not have any influence on the reflectivity of the material whatsoever.\nHowever it does, as by lowering the specular parameter on the Principled BSDF visibly reduces the reflectivity on the edges of metals in a physically unexplainable way. When setting the specular value to 0 the Principled BSDF then uses the F(0) value as reflectivity at all angles.\nI am not sure if this is a bug or a feature, but even if this were a feature there isn't a single source which mentions how the specular parameter influences the Fresnel equation (or in the case of the Principled BSDF Schlick's approximation) mathematically, so if you know where that would be documented please share it with us.\n[Test2.blend](Test2.blend)\nTest file with cylinder, specular value increasing from bottom to top, raised to the 4th power to make effect more visible.\n\nNow even if this were a bug I think, that we should keep it as, being able to control the Fresnel like this is a very handy feature however there is a problem, which is that the specular value does not control the reflectivity of the Principled BSDF if the transmission value is 1.\nIn the below file for both planes the specular value increases from left to right, while the top has transmisson=1 and the bottom plane has metallic=1, the reflection of both planes have been reduced to show just the glossy reflection.\n[Test file.blend](Test_file.blend)\nAs can be clearly seen on the bottom plane the glossy reflection increases with increasing specularity however on the top plane stays the same.", "Shadow buffers\nIn order to reduce Shader register pressure during shading phase, we need to transfer the shadow sampling of opaque surfaces to a fullscreen pass.\nWe would store 1 or 2 bits per lights (limiting number of shadowed lights per pixels to 32 or 16) and use noise to dither the shadow shape.\nThe noise would disappear with accumulation.\nThis idea was explored in this presentation [link](view).\nThe issue is that this technique will not work for alpha-blended surfaces that will still need the standard shadow code.\nContact shadow and cascade shadows cost could be reduced.

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.

[ "Add Object Tool, Resolve UI Issues & Polish\nThis task is to track the add-object tool.\n\n- - [x] Resolve behavior when axis aligned, see: #57210 (currently creates very large object). Done 1501c3adad\n- - [ ] Review design changes proposed by @DanielBystedt #57210#1010083", "Retopology in Blender\nThis design task is the proposal of implementing settings, operators, and tools that are useful for retopology work.\n\nThe biggest driving reason behind this proposal is that retopology work in Blender involves either an ad-hoc set up or add-ons (whether purchased or free). This is due to the very specific nature of retopology work. In particular, retopo work involves the creation of new source geometry (similar to modeling) and pushing around source geometry to straighten edge loops or relax stretched or skewed faces (similar to smooth sculpting brush). However, through all of the manipulating operations, the source geometry needs to remain on the surface of target mesh(es). This means that the tools need to follow up their edit with a snap operation. Due to this closeness, though, the source geometry could be hidden by the target mesh, so care must be taken to ensure the target geometry is appropriately visible over the target(s).\n\nThis proposal aims to bring the following ideas into Blender:\n\n* Edited geometry of retopo mesh will automatically snap or project to the surface of another mesh\n* Retopo tools will aid artist by solving specific problems typical of retopology work (i.e., high-level tools)\n* Source geometry will render over targets (in most cases) without showing through (similar to x-ray or in-front)\n\nThe [Retopology Mode ](Retopology_Mode) design document goes into some details about retopology work along with arguments behind some of the design decisions I made.\n\n\nWork Done\n****\n\nThis section describes the work that has been done so far. Some of my work has already been committed, some is still under review, and some of my work has been abandoned for more generalized approaches.\n\n[[D14035](D14035): Retopology Mode and Overlay ](D14035)\nThis patch has been abandoned, as Campbell thought a more general approach would be preferred. Note: left here to show extent of this work.\n\n[[D14591](D14591): Transform Snap: added nearest face snap mode, added snapping options, lightly refactored snapping code ](D14591)\nThis patch allows transformed source geometry to snap to the surface of target meshes, which is critical for retopology work. A few notes:\n* This method is different from the previous `Face` (now `Face Raycast`) snapping method, as the previous method snapped to the first visible surface under the mouse (raycast through mouse position from view). The new method allows the vertex to snap to the nearest surface, even if it is not visible.\n* This feature is cherry-picked from [D14035](D14035).\n\n[[D15154](D15154): Expose option to support fallback tools keymap in GizmoGroup type ](D15154)\nThis patch allows a `WorkSpaceTool` to use the fallback tools (ex: Select Box) when the mouse is not hovering the active `GizmoGroup`. With this, a new tool can act similar to the built-in tools like Move.\n\n\n[[D15398](D15398): Expose snap options in transform operators ](D15398)\nThis patch allows a tool to set specific snapping options without having to alter the global ToolSettings. With this, each tool can use the snapping options that are appropriate for the given tool. For example:\n* A geometry pen tool would operate best when Face Raycast is enabled (with Face Nearest as a fallback), as it operates on only visible parts of the mesh.\n* But a circumference loop tool will likely work on geometry that wraps around a target, so having Face Raycast enabled is not ideal.\n\n\n[[D15406](D15406): Add Retopology Mode as Snapping Option ](D15406)\nRetopology work involves the creation of new geometry (similar to modeling) but with snapping enabled by default. However, the potential snapping targets will depend on the snapping method under consideration. Specifically, source geometry should snap to the\n\n* surface of non-edited target meshes, but not to the surface of the edited source meshes, but it should snap to the\n* vertices of the edited source meshes, but usually not to the vertices of non-edited target meshes (exception might be CAD or certain hard surface retopo work)\n\nWithout this patch, there are only two options for achieve similar goals (listed below), but neither are ideal.\n\n* The user can make the deliberate change between snapping to target or snapping to source. This can be done before starting snapping through Tool Settings, or possibly through a keyboard action (but would require modifying Blender source)\n* Implement specific snapping routines for the tools to use rather than the built-in snapping methods.\n\n\n\nOngoing Work\n****\n\nThis section describes the work that is still ongoing. Some of this work is dependent on a few patches still waiting to be committed into Blender.\n\nTool: GeoPen\n-----------------\n\nI have a working prototype of a geometry pen. This tool is similar to Poly Build, but there are differences. Note: some of the differences are simply limitations in Poly Build and could be fixed.\n\n* GeoPen works with the current selection, while Poly Build uses nearest geometry.\n** Nearest geometry is determined in screen space, and *unfortunately* does not account for occlusion.\n* GeoPen works with any geometry, while Poly Build extends only from boundary edges.\n**Poly Build ignores loose edges and internal edges (edges between two faces).** Poly Build cannot create new disconnected patch of geometry.\n* GeoPen allows for repositioning of more geometry than a single vertex.\n** Nearest always has a result, so cannot use fallback Box Select with `LeftMouse` drag. Can use `B`+`LeftMouse` or switch tools...\n* GeoPen passes snapping options as arguments, where Poly Build requires user to set and enable manually (optionally use `Ctrl` while transforming).\n* GeoPen is written in Python as a proof of concept, where Poly Build is built into Blender.\n** GeoPen does work around some limitations in bpy (see [Experiments: Retopo Translate ]] and [[ https:*wiki.blender.org/wiki/User:Jon_Denning/Reports/2022/Experiments#geopen_hiccups | Experiments: geopen hiccups ](https:*wiki.blender.org/wiki/User:Jon_Denning/Reports/2022/Experiments#Retopo_Translate) for more details), but this type of tool should be able to be implemented on either side of the API.\n\nOut of all the differences, the first two are key differences in operating paradigm... how the tools operates. While a few of Blender's tools operate in a modal mode (e.g., Knife, Make Line), most of Blender's tools allow the user to change selection and operate on that selection via a Gizmo (e.g., Extrude Region, Inset Faces, Bevel, Smooth, Edge Slide, etc.). Valid arguments can be made for either approach.\n\nThe main argument behind using selection rather than nearest is: the tool does not make decisions on the behalf of the user. In other words, it is always clear what GeoPen will do next as the context is clear, while Poly Build depends on where the mouse is relative to the projected geometry (which comes with its own set of known quirks like rounding errors).\n\n\nBlender Manual\n-------------------\n\nI have started updating the [Snapping Options ](snapping.html) of Blender Manual to reflect the work listed above.\n\nA possible option is to add a subsection that discusses retopology-specific work, but this would better fit under a Retopology section, especially when more tools are ready.\n\n\nRender\n---------\n\nAs the retopology mode patch was abandoned, this area of retopology might not get touched.\n\nAlthough, I do have some ideas on a button / add-on that can adjust settings to be more ideal for retopo work.\n", "clay strip brush (and probably any brush) create some strange shading and geometry artifacts...\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.89\n\nBroken: version: 2.91.0\n\nclay strip brush (and probably any brush) create some strange shading and geometry artifacts...\n\n1. open blender, subdivide the default cube in edit mode a few times,\n2. add subdiv modifier with 3 levels (25,1 million in total) and apply modifier.\n3. go to sculpt mode and start playing with the clay strip brush and brush settings a little bit...\n4. change the sculpt plane to view plane, and add a stroke continuously in the edge of the cube, and some transparent shading bug appears when i go to check the back side of the stroke made, but this get fixed when i use the smooth brush a little bit in those boundary edges...\n\n\n5. change the sculpt plane to area plane again, and try on other edge the same again, and some grid topology starts to appear suddenly in the first stroke when drawing, but when i keep drawing it was less noticeable the artifact but was still there...\n\n\n\n", "Edit Dyntopo Detail Size unreliable for small scales\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30\n\nBroken: version: 2.92.0 Alpha\n\nSculpt Mode >> Shift + D \n`bpy.ops.sculpt.dyntopo_detail_size_edit` / Edit Dyntopo Detail Size *(for Dyntopo detailing set to Constant detail)*\n\nThis operator is supposed to show a grid preview of the mesh density applied from strokes using Dynamic Topology. \nNormally this works, however when a mesh is small, relative to the 1 BU / CM, it becomes too slow/fast to change the resolution, and when the density is too high *(for a larger mesh)*, the resolution bumps up to a higher size, removing the ability to even preview the density after manually adjusting to a more acceptable resolution. \n\nTake a cube, and subdivide it 4 or 5 times.\nWith cube at the default size of 1 BU, use the eyedropper to sample the cube's density, then adjust the detail size with this operator *(Shift+D)*, \n\nNext, scale the cube down to 0.1 and repeat. \nNotice how much harder it is to adjust the size. \n\nNext scale the cube down to 0.01 and repeat. \nNow, you will see the grid flash a dense resolution and quickly bump up to bigger triangles. \nAlso, the operator has a secondary option of Ctrl+Clicking to sample from the mouse.

I have noticed that a weighted normal modifier makes masking completely invisible in sculpt mode. I don't know whether this is a bug, but it can sometimes make things confusing and make you wonder did you hide your mask accidentally. \n\nAlso, there's no notifications to inform you that the weighted modifier is the culprit, so the user might spend quite some time figuring out what's wrong with masking in sculpt mode before he gets to the modifier stack it took me quite a while before I noticed that I had that modifier on. \n\nIf that is an intended behavior then the user should be notified that masking won't show up with a weighted modifier toggled on, or it should be toggled off automatically upon entering the sculpt mode? (I know that you can turn of deformer modifiers in the options tab though not everyone uses that by default)\n\n1. - Create any geometry\n2. - Apply weighted normal modifier to your object\n3. - Go to sculpt mode \n4. - Use any masking tool, there's no mask" ]

A big reason is that undo writes and reads all datablocks in the file (except from linked libraries). If we can only handle the ones that actually changed, performance would be much improved in common scenarios.\n\nThis proposal outlines how to achieve this in 3 incremental steps. Only 1 or 2 of these steps would already provide a significant speedup.\n\nAt the time of writing there is no concrete plan to implement this, but I've had this idea for a while and it seemed useful to write down in case someone likes to pick it up.\n\n## ~~1. Read only changed datablocks~~ DONE\n\nLinked library datablocks are already preserved on undo pop. We can do the same thing for all non-changed datablocks, and only read the changed ones.\n\nWe can detect which datablocks were changed by checking that their diff is empty. Addition and removal of datablocks also needs to be detected. We need to be careful to exclude runtime data like `LIB_TAG_DOIT` from writing, to avoid detecting too many datablocks as changed. Most changes to runtime data go along with an actual change to the datablock though.\n\nSince unchanged datablocks may point do changed datablocks, we need to reload datablocks in the exact same memory location. We can safely assume the required memory size stays the same, because if it didn't those other datablocks' pointers would be changed as well. In principle other datablocks should not point to anything but the datablock itself, but there may be exceptions that need to be taken care of *(e.g. pointers to [armature] bones hold by [object] pose data...)*.\n\n`Main` fields other than datablock lists may need some attention too.\n\n## ~~2. Optimize post undo/redo updates~~ DONE\n\nThe most expensive update is likely the dependency graph rebuild. We can detect if any depsgraph rebuild was performed between undo pushes, and if so mark that undo step as needing a depsgraph rebuild. This means the undo step is no more expensive than the associated operation.\n\nThis requires the dependency graph to be preserved through undo in scene datablocks, similar to how images preserve image buffers. This would then also preserve GPU data stored in the dependency graph. If the dependency graph supports partial rebuilds in the future, that could be taken advantage of.\n\nThere may be other expensive updates, to be revealed by profiling.\n\n## 3. Rethink how we handle cache preservation across undo steps.\n\n#76989 seems to point to some pointer collision issue, similar to the reason that lead us to add session uuid to IDs when we started re-using existing pointers in undo.\n\nNote that according to the report, there were already issues before undo refactor - hard to tell though if they had the same root cause?\n\nThis needs to be investigated further.\n\n## 4. Write only changed datablocks\n\nWhile undo/redo is usually the most expensive, the undo push that happens after each operation also slows down as scene complexity increases. If we know which datablocks changed, we can only save & diff those.\n\nThis could be deduced from dependency graph update tags. However there are likely still many operations where tags are missing. If it is not done correctly, then instead of a missing refresh there is a more serious bug of not undoing all changes. So this needs verification throughout the Blender code for correct tagging, before it can be enabled.\n\nDebug builds could verify correctness by testing the diff is empty whenever there was no tag.\n\n\n-----------------------------\n\n\nCurrent Status and Plan\n****\n\nThere is an experimental option in 2.83 to address step 1 and (part of) step 2. This was developed in branches and is now in master. Implementation of step 3 has not started.\n\n- [x] [id-ensure-unique-memory-address]() implements the idea of never re-using a same memory address twice for IDs. This is required to allow usage of ID pointers as uids of datablocks across undo history.\n - [x] Add storage of addresses history for each ID (has to be stored in blend memfile, can be ignored/reset when doing an actual blendfile reading).\n - [x] Discuss how to best implement the 'never get same allocated address again' process, current code here is basic, we could probably be much smarter and efficient with some changes to our MEM allocator itself.\n - [x] We are going to try and use session-wise uuids for data-blocks instead.\n - [x] Make new undo behavior controllable from Experimental preferences area.\n- [x] [undo-experiments]() Implements detection of unchanged datablocks at undo, and re-using them instead of re-reading them.\n - [x] Switch to using id addresses instead of names to find back a given data-block across undo history (depends on completion of work in `id-ensure-unique-memory-address` branch).\n- [x] [undo-experiments-swap-reread-datablocks]() implements re-using old ID address even for changed IDs that need actual reading from memfile. Also adds support for more refined depsgraph update flags handling from undo. Both changes combined allow to reduce dramatically depsgraph work needed during most undo steps.\n - [x] Switch to using id addresses instead of names to find back a given data-block across undo history (depends on completion of work in `id-ensure-unique-memory-address` branch).\n- [x] Investigate crashes due to invalid or used-after-free memory in depsgraph after undo step.\n- [x] Investigate why some undo steps are still using full reload of the memfile. Some may be necessary, but think we can improve here.\n - [x] In particular, the absolute last undo step (the first to be undone) is always seen as 'all data are changed', for some reasons...\n- [x] Investigate how to discard runtime data from 'data is changed' detection (probably by nullifying those pointers at write time?).\n- [x] Fix slow undo of adding/duplicating/deleting datalocks. The undo diffing does not appear to be smart to match up the right datablocks in such cases, causing many unrelated datablocks to be marked as changed, which also means excessive memory usage. The `session_uuid` could be used to find matching datablocks.", "Nodes: Assert and crash: Editing nodes through the material panel and undo.\nOperating system: Windows-10-10.0.19043-SP0 64 Bits\nGraphics card: Intel(R) UHD Graphics 600 Intel 4.5.0 - Build 27.20.100.8729\n\nBroken: 3.4, 3.3, ... 2.8\nWorked: never\n\nWhen I select certain nodes from the materials tab after pressing undo on the last node change, blender crashes.

This is the new [BlenRig 6 ](660103) Rig and ever since we got library overrides people have been experiencing a certain lag when selecting bones on a linked rig.\n\nThis lag can go from milliseconds to a couple of seconds depending on scene load and CPU.\n\nBastien Suggested that disabling Global Undo could fix the lag and indeed it does fix it... but you know, it's not practical to be forced to working without Undo...\n\nIn the zip you will also find two files called \"no_overrides\", there I turned off library overrides for all properties. Unfortunately, the lag is still there when you link the rig.\n\nI really don't know what could be causing this, animation playback works just fine, the lag happens when selecting bones and when scrubbing through the timeline. Maybe you could do some debugging and see what blender is doing on those two operations and why it's taking so long to perform them. \n\n- Unzip the attached file - you will find the files \"character\" and \"link\"\n- Open the file `link.blend`\n- Select some bones to check the performance\n- Go to {nav Blender Preferences > System} and disable `Global Undo`\n- Select some bones to check the performance\n[lib_overrides_lag.zip](lib_overrides_lag.zip)", "Undo doesn't work with paint mask selection (texture paint vs. vertex/weightpaint)\nOperating system: Linux-5.2.10-arch1-1-ARCH-x86_64-with-arch 64 Bits\nGraphics card: Radeon RX 580 Series (POLARIS10, DRM 3.32.0, 5.2.10-arch1-1-ARCH, LLVM 8.0.1) X.Org 4.5 (Core Profile) Mesa 19.1.5\n\n\nBroken: version: 2.80 (sub 75)\nWorked: (optional)\n\n\nUndo does not work with paint mask selections.

But this leads to using `Invert` on the mask potentially hundreds of times per day.\n\n### Syncing Selections across Modes\n\nFor the implementation of Paint Mode it will be very beneficial to start syncing selections between various modes. \nSo if a selection is made in Edit Mode it will also appear as masked in Sculpt/Paint Mode (This would likely be a direct conversion every time you switch modes)\nThis will be less confusing and disconnected if both the selection in Edit Mode and the mask in Sculpt/Paint Mode are areas you CAN affect.\n\n### Masks vs Selections\n\nA current plan for the implementation of Paint Mode and the new Curves object type is to use \"Selections\". \nThe use case for sculpt mode masks and selections is essentially the same: \n**You define a temporary area that should be affected by your operations.**\n\nThe issue is that \"Masks\" also refer to the concept of for example creating an attribute (like a vertex group or color attribute)\n or a grayscale image texture and using it as a factor for shader/geometry nodes. The use case here is quite different:\n**You save an area for repeated use in materials and procedural networks.**\nFor example layering textures.\n\nReplacing the current concept of sculpt mode masks with selections would avoid confusion and make the use case of selections and masks very clear.\n\n# Proposal\n\n### Selection instead of Masking\n\nWe need to test the following behavior:\n- Rename \"Mask\" to \"Selection\" or \"Selection Mask\"\n- Unselected areas are darkened with an overlay\n- Selected areas are affected by brushes & other operations\n\nThere are use cases that are important to keep in mind with this change:\n- When entering sculpt mode, everything should already be selected.\n- Previous workflows (Mask brush) to create a deselected area and should still be accessible.\n\nOther areas of Blender will still refer to \"Masks\" like a Texture Mask in the brush settings, mask nodes, grease pencil layer masks and motion tracking masks.\n\n### Offer a preference to use the old behavior\n\nThere should be an option in the preferences to invert the selection behavior globally in sculpt/paint mode and get the old behavior back.\nTo what extend the inverted behavior would be done needs to be tested.", "Texture Node Editor Using nodes causes weird issues in sculpt mode.\nOperating system: Linux-5.15.0-48-generic-x86_64-with-glibc2.31 64 Bits\nGraphics card: NVIDIA GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 515.76\n\nBroken: version: 3.3.1\nWorked: perhaps never?

The first image shows a cube with a color attribute added. The geometry nodes setup adds a red color to the \"Color\" attribute. This all works as expected as can be seen in the viewport and the spreadsheet. \n\n\n\nIf a GN cube is added instead of the standard mesh cube (which has been bypassed by the switch node) then the color attribute is added as expected. This can be seen in the spreadsheet as to be the same as the previous screenshot for the color attribute. However, it is not being displayed in the viewport.\n\n\n\nThis is a problem seen with any procedural geometry made with just nodes. As a workaround, you can have a single vertex as the only \"real\" geometry and use a join node to join with any nodal procedural geometry. Strangely though, this has to be the first connection in the join node, and won't work if it is second. This can be seen by the next 2 images:\n\n\n\n\n\nA similar related case is that some mesh nodes will also make the viewport lose the displayed attribute. For instance, if you create a cube, add a GN modifier and add a dual mesh node to the chain, the color attribute is still there, but no longer displayed in the viewport. This happens with some nodes (like mesh to volume and back to mesh) but not others (like subdivide or extrude).\n\n\n\nThere is also a related issue that when exporting to obj or gltf the color attributes are not exported if they are not displayed in the viewport. If apply the GN modfier, you have to actually click on the color attribute in the properties panel to see it in the viewport or to be able to export it. \n\nOddly, the fbx exporter seems fine without applying the modifier. It also doesn't matter if the color attribute is on the vertices, or face corners, or if the color is float or byte color.

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 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.

[ "Custom Manipulators: General Design & Functionality\nThere are a number of features that should be supported but further design work is needed before they can be implemented properly. Everyone is welcome to join the discussion by proposing more ideas or solutions, by creating mockups or by just giving some own input.\n\n----\n\n# Scope of Widgets\n\n### Description\n\nWhen should a tool use a widget?\n\nExamples:\n\n* Edit Mesh Spin Tool\n* Edit Mesh Smooth tool (number of steps, smooth factor)\n* Edit Mesh Bevel/Inset\n* Edit Mesh UV Rotate\n* Edit Mesh Subdivide\n\nSpin tool is an example where widgets make a lot of sense (you rotate around an axis, so direct manipulation is useful).\n\nThe issue with Smooth & UV-Rotate is that using a 3D manipulator for these is using manipulator simply as a way to access buttons in the view-port.\n\nAn issue with bevel/inset depends on the kind of manipulator used. Having a single manipulator in the view doesn't directly relate to the edge, and again - its more a replacement for accessing buttons in the tool-bar.\n\n### Proposed Solutions\n\nSuggest not to use manipulators if they are simply an alternate access to buttons.\n\nAs for bevel/inset: we could make the bevel edges themselves into manipulators, so you could click on beveled edge and drag it.\n\n----\n\n# Toggling Visibility of Widgets\n\n### Description\n\nCurrently, only the widgets of the active object are drawn. While this works for most cases, being able to precisely control which widgets are visible and which not can be useful.\nFor example, in future, a camera could have widgets for the focal length, sensor size, depth of field distance, ... If all are visible all the time it's easy to accidentally manipulate them.\n\n### Proposed Solutions\n\n* Draw a panel for the active object in which its widgets can be enabled/disabled individually (similar to \"Display\" for cameras).\n* Add a toggle button next to every button represented by a widget (similar to how it's done in the transform panel in the properties region, where you can press the 'lock' icon to disable the widget for this axis)\n\n### Open Topics\n\n* Where would the manipulator toggles be stored? (Object / Viewport / Tool-Settings)\n* How to expose settings that aren't related directly to objects? (Group Center, View-Port Clipping Bounds)\n\n----\n\n# Numerical Input\n\n### Description\n\nIt should be possible for users to input precise values to manipulate a widget (and thus the value it represents). This way they can keep their locus of attention in the viewport, avoiding having to search for a button in the UI.\n\n### Proposed Solutions\n\n* Enabling number input by holding a modifier key while clicking on widget (as in - Ctrl+LMB on widget activates modal mode to input value)\n\n---\n\n# Snap System\n\nUsers may want to snap manipulators to other elements in the scene, eg:\n\n* Snapping the spin center-point to a vertex on a mesh.\n* Snapping bisect angle to a vertex\n* Snapping the camera's DOF to the surface of an object.\n\nNote that currently holding Ctrl sets `WM_MANIPULATOR_TWEAK_SNAP` but each manipulator needs to implement this.\n\n### Proposed Solutions\n\n* Each manipulator has a snap flag for 'TRANSLATE | ROTATE | SCALE', when set, holding Ctrl will snap to any of the elements set.\n* Snapping can also respect scene settings (in the 3D) view-port, so users can snap as with mesh edit-mode.\n\n----\n\n# Key Framing\n\nWhen the cursor is over a manipulator, do we want to support I-Key to keyframe that setting (DOF, lense for eg).\n\n----\n\n# Theme Colors\n\nManipulators now use theme colors, there are basic preset colors to use: (HIGHLIGHT, PRIMARY, SECONDARY, A, B).\n\nWhere A/B are for other controls.\n\n*Currently they're hard coded in manipulators but they can be set however we like.*", "Uncontrolled vertex movement in symmetric editing\nOperating system: Windows 7\nGraphics card: AMD Radeeon `R9` 200 Series\n\nBroken: version: 2.82 (sub 7), type: Release; build date: 2020-02-13, 01:56:46\nWorked: (optional)\n\nWhen symmetrical editing about the X axis with proportional editing of an almost symmetric object, model changes are detected in places where editing was not performed. \n\nMoreover, these changes occur asymmetrically. For example, in a key with a changed shape of the legs of a human model, a significant asymmetric change in the neck region with a shift of the line of symmetry itself was found. So it is with most other shape keys. Thus, the symmetry of the entire model is violated, which entails other undesirable consequences.

So a smooth surface gets a non-smooth (faceted-looking) surface on the other side. \nHowever, activating the Normals --> Flip option in the modifier actually produces the correct (smooth) normals on the new geometry, but destroys the custom normals of the original surface. The newly created surface then has flipped normals, but these can be flipped again inside edit mode after applying the modifier. They are then facing the right way and still smooth. So the modifier actually has the code to correctly calculate the new split normals.\n\n\n- Take a mesh surface with custom normals, make two copies.\n- Object 1: Add a solidify modifier with a relatively small thickness. Look at the newly created surface: it's not smooth but faceted. \n- Object 1:Apply modifier, turn on display of custom normals, zoom in on new geometry: the normals on the new vertices are divergent.\n- Object 2: Add a solidify modifier activate with Normals --> Flip. Look at newly created surface: it's smooth as the original one. Great. But the original surface is now broken up and not smooth.\n- Object 2: Apply modifier, turn on display of custom normals, zoom in on new geometry: the normals on the new vertices are identical, do not diverge, they are simply facing the wrong way. Apply \"Normals (ALT-N) --> Flip\", now they are correct.\n\nSo basically there is a work-intensive workaround (which also means losing the flexibility of having a modifier): make two copies of the object, add modifer with flipped normals, apply, flip normals again in edit mode, manually select and delete original geometry, join with the original object (original geometry). This is what the modifier itself should be doing.\n\n- See the attached Blend file.
