I really don't know about Poser Pro........mostly because things came up in my life and I couldn't spend the money for it......but.......if you have "Bryce" maybe this tutorial will give you some ideas. I think perhaps, with a few modifications.....it may work for/with other programs too. (: Use your imagination...you never know what you may come up with. Genny
