I've been running into a problem when trying to create hair in maya. 

If I select the head/scalp and duplicate the mesh it causes all sorts of errors with the hip bone down the road when trying to reimport it. Duplicating causes errors.



This duplicate mesh technique is used in https://www.youtube.com/watch?v=E7f__LNUviw to create a scalp for hair.

I plan on using xgen to create hair and they use this same technique (a scalp mesh). Since the Iclone/cc hierarchy bugs from any kind of duplication, what can I do? Manually drawing all the polygon faces on a head mesh takes forever!
