I am trying to make one of the figure transparent. Everything is fine, until I try to do this to the head. When I go to make head transparent, You can see all things inside the head. Gum, teeth, etc. It looks awful. So I go and make all the rest of the stuff even more transparent, but doesn't really help much. Is there a way to make these parts invisible? I don't see anywhere to do so like you can with all the rest of the props. I am using P6 if that makes any difference. Please help if you can! Thanks!
