I like the way you wrote this question, unfortuently would take you or I a little longer than this to expect a free handmedown, fo P5, in magazine or something... P5 is definatley an improvement, with substantial gains toward many "Modelers." Its collision detection is a very powerful feature...(Not many peopl mentioned that because it is something new to learn...) The Setup room is another "Modeler" like advancement, I'm not sure it it is much more than P4, but now Grouping(A key feature in making your own poser characters,) has it's own "Room" dedicated. The face room is also a big help, you can randomly make as many faces as you need now. And then there are all the Pro Pack features that have been transfered like Multiple windows, and Python Scripts that are both a must for serious attention givers! I'm not %100 proof posotive the new Firfly Render Engine is a success, but it ai'nt bad, and I hav'nt heard hardly any negative feedback...Though I think many people, like myself, were really expecting a dramatic improvement in any engine change...maybe like that to the quality of Bryce/Vue or better. Allthough that may not be all together true as Some improvement may have been necessary just to keep up with the new Collision Feature. = )
