Why stick with P4? Well, as it is now, P5 is pretty much useless for my needs. Since all of my poser work is intended for rendering in outside programs, and none of the "new" features of Poser 5 will export (hair, cloth, etc,) then I can't use it. And if I can't use it, I don't need it. It's that simple. I'm sticking with Poser 4 and ProPack because they DO work for what I need to do. Heck, I've even taken P5 off my machine since it's useless to me. Need the space for other things.
