read me!!
in order to get the same result as the preview download the .blend file <3the rig contains a lot of drivers and constraints that is why the rig is going to only work on .blend file
the file contains 20k triangles and 10k vertices :)
the shadow does contain alpha channel and it is fine to delete the sahdows , it will not effect the rig
