For Blender 3.2

This is a list of various other tasks to work on before the release of Blender 3.2.
All these relate to the recent additions of painting tools in sculpt mode and color attributes D12587. The goal is to fully test the features and polish them for the release.

  • Mask by Color tool don't create a new color attribute. Instead moves geometry on click & drag

For Blender 3.3

  • BMesh Python API
  • Update importers and exporters for new color attributes (maybe as part of general attributes support)
    • USD
    • Alembic
    • Add-ons
      • Wavefront obj
      • fbx
      • more

Other Tasks

Additional features and improvements for later.

  • Multires support
  • Optimize GPU storage by storing colors per vertex instead of per loop when possible

@JulienKaspar @JosephEagar
The Color Filter in the Sculpt-Dev branch has this set of "Random" functions for (Hue/Saturation/Value), which are very useful for the obvious reasons, but they are missing in the master build...
So, could those functions be part of this list of "Color attribute painting improvements" and be ported to master? Would be great to have those... Cheers...

Also kinda curious why Obj is not on the list of the importers/exporters to support vertex colors... 🤔

@TheRedWaxPolice There are many features from sculpt-dev that need to be committed. Small and big. We'll work on a full overview of tasks.

And yes, the importers/exporters are not just about the mentioned formats but any format at supports vertex colors. We should add the rest to the list. 👍

Good to hear you guys are going to work on moving the sculpt-dev features into master.. 🙂
And yeah, there are many features, but I just mentioned those because it's related to vertex colors... also I thought it could be a bug or maybe an oversight with an easy fix... 👍

Looks like the geometry nodes team added BMesh python support for float colors in 2020, I still need to test it though.

Because it's not implemented yet -- the existing OBJ impoters/exporters in Blender don't support vertex colors. I have a plan to do that someday, but this should not hold up the 3.2 release actually -- none of the color changes affect OBJ, if only because right now OBJ blissfully ignores vertex colors.

I'll close this task. The #pipeline_assets_i_o project will handle the remaining attribute support tasks. Fbx, obj and glTF are alreayd supported.
Multires support will be handled by #93165 and any future mutlire project.
"Optimize GPU storage by storing colors per vertex instead of per loop" is a low priority task that @JosephEagar will handle at some point.
