Heya. I just want to know how ProPack differs from the normal version. I've never cared, but I hear you need it to make things for Poser. I got Rhino at Christmas and now I have a reason to figure out what PP is. I have as yet done any research, but I had a though hearing it from people who use it would be helpful. So, thanks for any information, links, or anything else that could be helpful. Ciao.
