The "Vertex Color" node was renamed the "Color Attribute" node (in 3.2 IIRC).
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 #…
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…
@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.…
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…
The generator is FBX2glTF. Perhaps this bug report is related: https://github.com/facebookincubator/FBX2glTF/issues/108.
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…

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