Understanding .glb model properly

[ChristofJugel]

Hello :)

Does any of you have a documentation on how the 3D models work?

I don't really understand how to animate color or add variants.

Generally I would recommend using animation software that exports to glTF like Blender or any of the big expensive ones. If you really want to generate them by hand or programmatically, I'd recommend the glTF VSCode extension and you can get started with the spec here: https://www.khronos.org/files/gltf20-reference-guide.pdf
