For those who render in Bryce I don't really think Poser 5 has that much new to offer. Since you cannot export the hair NOR the materials, those are pretty much useless. As is the renderer. Cloth is okay and rather neat for special purposes. The face room is neat also, but if you're not into closeups it doesn't really matter. It's easier to read the parameter dials and libraries are easier to deal with though. And it has all the features (except exporters) of the ProPack like multiple view and Python scripting which is a good selling point. Of course, you could try doing renders in Poser only...big learning curve...but scene building is difficult without the tools of a real rendering package. And if you're used to doing your own scenes, you really don't want to purchase background stuff that everyone else is using too. But it does give an opportunity to try new things, like portraits, for example. Lots of interesting new ways of using Poser lighting have come about in the past year that in combination with the new 'atmosphere' stuff can give you very nice output in less time than you can do it in Bryce.
