Converting TexturesVertex to TexturesUV / save as .mtl file?

[mark-at-hypothetic]

The goal is saving my mesh's vertex colors as a texture .mtl file.

I guess, a logical step would be first to convert the colors from TexturesVertex to TexturesUV? Is that possible?

I've seen it being done the other way around in this discussion, but haven't found a way to do the reverse yet.

If impossible, anyone know of a tool that does it which I can embed in my python pipeline? I think baking vertex colors to the mesh is probably possible in the Blender Python API but haven't gotten that to work yet either.

There's no particular facility in PyTorch3D to help you do this. You need to come up with locations of each face in the UV-plane somehow.

Alright. If anyone has a good implementation for that I'd be interested to hear
