On the other hand if the two sets are completely uncorrelated then it gets more complex: A fully generic brute force solution would be to read 1 of the vertex attributes of the known mapping. Does anyone know how to obtain the data in maya called the component ID of the vertices. It uses the API to get bounding boxes for all the uv shells in an object (note -- it should be a mesh shape object , I didn't add any checks). After a lot of searching and testing it seems like it's impossible to import an 3D-object with it's UV-mapping and texture from another 3D-software into Blender.
