Transfer UVs from unskinned to skinned mesh

TransferUVsToSkinned

import maya.cmds as mc
'''
Just copy and paste this code into script editor, select the source mesh with correct UVs, then select target skinned mesh and execute the code

If you run transfetUVs(1) if will transfer UVs according to the mesh topology, if you will run it with transfetUVs(0) it will transfer UVs according to the
mesh components. It may not work correctly if the vertex order somehow changed, so keep in mind that 'Topology' method works more correct, hence recommended usage is
transfetUVs(1). Also keep in mind that it works in 99.5% cases, but is is not silver bullet in cases where topology and components are different, so check every mesh after
UV transferring.
