I'm sorry I couldn't be more helpful. I've never gotten to grips with 3D modeling, and actually ebded up deleting Ray Dream Studio (the old one, with the duck) from my machine because I never used it and needed the space. Yes, it's bits on the legs of the figure to make transparent; that way geometry that pokes through the skirt doesn't show. I just don't understand the underlying mechanics of it all. What I do understand is: Paint Over the Bit That Doesn't Look Right. Postwork is my best friend.
