how to assign specific uv set to xgen?

[otabek_1]

I have a character and it has 2 uv sets and I want my xgen to utilize 2nd uv set of my character. So the issue I'm having is that I'm import collection to another scene and all my xgen maps are painted for second uv set. I'm aware of that xgen use .ptex which is not uv based however whenever I want to make some changes in groom, ptex files are ruining after baking them. Ptex files are getting baked based on first uv set.

Create a scalp mesh. With only one uv set. 

xGen is based on Ptex. It does bake anything ot Ptex in the end.

Your animation mesh should not be your groom mesh.
