I use P5 exclusively... actually, I never owned a poser program before P5. I guess the reason that more P5 users aren't replying to this message is that we're too busy rendering cool things. Frankly, I love all the rooms- the setup room is great; most of my props are now figures, the hair room is nice (if a bit tricky to work with), and the possibilities of the Materials room are incredible. Try a raytraced reflective metal texture in both the Firefly renderer and the P4 renderer, and you'll see that P5 is truely impressive. I've never had problems with the speed of the rendering, then again, I do have a semi-buff machine. Sorry if this seems like a flame-bait post- I just thought some of us P5 lovers should speak up, since we seem to be under-represented.
