It's FULLY functional. There are no restrictions other than the time limit, which should be good enough for me to figure out how to use all of its functions.
Saturn Girl should only be one or two layers. When they say that, they are referring to UV mapping and painting the textures. I played with it for a little while yesterday, and I figured out a couple things using the Blaze bodysuit as a guinea pig. It does a really nice job as you can imagine, but I don't know enough about the UI right now to do a really good job of UV mapping. And I don't know how to paint in it yet.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
