havent had C5Pro very long either, mostly only played with lighting and materials, it can also model though the render speed is greater, supports dual proccessors, along with network rendering, which is nice, and global lighting is nice P6 and C5P both have ups and downs with materials though in P6 you have slightly more control of what goes where whether it be driven by stupidity or not :P while C5P seems just a bit more "it doesn't belong there, so not available" and it also lacks (as far as i can tell) posers N node which i use quite a bit in doing things C5P does however have a "formula" node, to allow you to program in endless math formulas, with the same language as VC++ so you can replace endless poser math nodes, huge plus overall you get more power, and just lose a few minor things i love it, i just want my damn N node >.< oh and haven't tried dynamic hair in it, but people keep saying they're having problems with it, and i'm moving into realism with my animations, so haven't pushed fully for C5P yet due to that
