Dennis- I have to confess that I haven't gotten around to testing Carrara's physics functions yet, which is strange considering my interest in animation. I've been so busy trying to learn the shader tree functions and familiarizing myself with the various modelers(I got Hexagon2 also) that I haven't done much more than some wind/tree animations and some experimenting with animated displacement maps. Carrara5 is so "deep" that I am sure that it will take me a quite a while to gain some mastery. So, while I don't know the answer, I encourage you to try it. After all, Carrara is a pretty robust app and I don't think you can break it by trying!:laugh:
