The problems I've heard of and experienced are: 1. The new way they handle figures makes exchanging figures a bit different. Any character with custom geom made with the group tool will get a new, overall obj file that would need to be distributed with the model. 2. There is a bug in the custom geom files that cause polygons to drop out. Its fixable but a pain. 3. Menu system can crash game. If you pull up a body part or props property dialog, then do a set parent, then lose focus, Poser loses the dialog boxes and you can't get control of the app nor can you use menus. Also, the set parent with the bend flag switched on causes this similar problem. 4. The Flash animation plugin is awesome. If you want to do flash work this is a must have. 5. The transfer to other apps like Max and lightwave was made smoother plus bones were added but I haven't heard rave reviews on this. 6. There's nothing new in the materials section. I would have loved a better selection method for materials. If I change a skin I have to either force all parts to this skin or systematically set each material seperately. Hopefully someone will write a python script to do this. 7. It supports python scripts. If you're just modelling its not real useful. If you want to write scripts to help with rendering and such then its a boon. Someone in the Python Forum has already written a random face creator that dials in random settings to get new faces. My feeling is if you just want to bring up a figure and pose and render them then PPP is probably not a good choice. If you want more higher end functionality, multi view ports, customizability through python, flash, max and lightwave support and bone controllers and are willing to deal with some annoying bugs then PPP is a consideration. PPP also has some funky little cartoon figures.
