I didn't try Poser 5 till SR2.1-- V3 came out and no way I could get all her 30 folders into my already crammed PropPack libraries. So I had to switch. It's been pretty good. I haven't tried a two person render yet. I've used the hair room-- to adjust ready made hair-- the materials room and I render in FireFly. That's it. I never did animations and I haven't seen the tutorial that worked for me in the clothroom. With only that, I like it better than Poser4-- it's marginally more stable. You cannot cancel if you are rendering to a larger window-- that's a known bug. It is slower but not that much slower and on the whole crashes less than Pro Pack which would crash once a day every day. Emily
