Suppose I know the following information:

vertices, faces and uv and uv_faces and vertex colors (features)

How can I render/interpolate vertex colors (features) to a texture map? Such as,

With careful pytorch indexing, the vertex uvs, face uvs and vertex colors determine a 2D point cloud which you can find. You then just need to interpolate it into an image.
