I develop for P4 and add P5/P6 extras, so I use all 3 apps. I've also been making separate versions of each product for daz studio, - same product, different installer, but modifed to work correctly, and with small extras thrown in that poser won't do. As jim burton said, cut out the P4 users and you're losing a large customer base. Almost everything that's made for P5 will work in P4/PP, other than dynamic cloth or special shaders. mac
