There is no "vertex color" node

The "Vertex Color" node was renamed the "Color Attribute" node (in 3.2 IIRC).

mathutils.Quaternion.slerp is non-linear

The effect you see is actually from a small bug in the script. start aliases obj.rotation_quaternion, so you are actually changing start in the loop.

start = obj.rotation_quaternion  #…

quaternion rotation values changing to inverse of what's needed when rotating beyond limits of current quaternion segment

I don't what Flip Quats (Alt F) does. I tried it and it appears to do nothing. But I don't think any operator you run after the fact could fix this; the information about which way you rotated is…

quaternion rotation values changing to inverse of what's needed when rotating beyond limits of current quaternion segment

@dr.sybren Starting from the default cube, view it from the top in object mode and hit R to start rotating. Spin around one full rotation counter-clockwise. It goes from 0 degrees to 360 degrees.…

quaternion rotation values changing to inverse of what's needed when rotating beyond limits of current quaternion segment

Note that this is inconsistent with Eulers, which work as expected. If you spin the bone around a full revolution in Euler mode you go 0° -> 360°. The equivalent for quaternions would be to go 1…

Error Import GLB file

The generator is FBX2glTF. Perhaps this bug report is related: https://github.com/facebookincubator/FBX2glTF/issues/108.

AttributeGroup API: "active" is meaningless (always refers to all attributes, not the specific AttributeGroup) -- e.g. mesh.color_attributes.active

Also if you create a color attribute by going into Vertex Paint mode, it will still incorrectly return attributes["position"]. If you create a color attribute by going through the Properties…

Dupe of blender/blender-addons#103392 probably.

Importing a GLTF file results in a broken material node tree

Importing a GLTF file results in a broken material node tree

This should already be fixed in 3.5+ by https://github.com/KhronosGroup/glTF-Blender-IO/pull/1821. You can download a beta from https://builder.blender.org/download/daily/ to check.

FBX/OBJ Import - Show Backfaces makes object look wrong and is ON by default.

That solves the most important case, which is when the alpha texture is all 1 so the material is morally opaque, which happens a lot with OBJ/FBX.

The downside is there are times when multiple…

Addons that use node_shader_utils.py import alpha blended materials incorrectly

Although closely related, this isn't an exact dupe. The new OBJ importer isn't written in Python anymore, so changing node_shader_utils won't do anything to it.

Color Attribute not affecting "bump" shader node

@mod_moder Use a "Color Attribute" (Add > Input > Color Attribute) node instead of an "Attribute" node.

Repros for me.
