Ok - I have all of my uvs for my character layed out.
They all show up in the UV editor when I select my character.
I want to make three seperate files for the character- face, hair, & body.
How do I make three seperate snapshots if they are all laid out in one texture window?
I tried making uv sets, but when I take the uvs for say the face and make a uv set, I lose the rest of the uvs. I have tried changing back to the old uv set, but I still dont have my uvs.

Help! - I am stuck in this spot until I find out what to do next.
