Description

1. create a mesh and a skeleton joints, the use bind skin to bind the mesh and the skeleton joints
2. deform the mesh, make the face count different from the original mesh
3. export usd with skin cluster automatically
4. the uv count of the mesh won't match the face index count of mesh(below)

so why use geomMesh only for geometric data such as vertices, faces, normals, but use finalMesh for UVs, if the face indices count of the geomMesh doesn't match with the finalMesh, then the he uv count of the mesh won't match the face index count of mesh in usd file
