One little detail of the CMesh cluster bugged me so I fixed it. I had flattened the output of MCol so it wasn’t going to work properly with branches.
Built a rather elaborate demo / test GH file, only to realize that the fix makes it possible to have one mesh in each branch but otherwise the mesh colors are unaffected, they were correct. 
The result of flattening in this case was to combine the mesh faces (colored correctly) into a single mesh instead of separate meshes. So weird that three meshes that don’t touch each other can be considered one mesh.
