"Poser 5. $300+. None of the features people requested. Didn't work right. Removed feature that we had in P4PP. No real continued development. Slow bug fixes because the development team working it was laid off."

The world is a funny place, because my experience with poser 5 was dramatically different :)

• Much better rendering engine... like LOTS of people requested. This includes better lighting, materials and shaders and resolution improvements
• Worked just fine for me. More stable or as stable as P4PP
• Added dynamic cloth, which while the market was too dense to ever embrace had the potential of forever getting us off the treadmill of having to buy new clothing or have clothing that didn't fit out figures.
• Added dynamic hair... again, the market hasn't figured it out (the Poser market is mostly amateurs so they are slow to learn new tech at times) but once you see how it can add life to a animation "helmet hair" seems lamer and lamer all the time
• Dramatically more productive asset management
• Constant improvements via the service packs that have addressed most of the bugs people had

Hell, the asset management along in P5 paid for the upgrade for anyone who was using the beast to make money. The time savings were outstanding. Coupled with Body Studio P5 is a solid production tool.

Of course it's a religious thing now for most people... they hate P5 cause, well, they just hate it! Thats OK, I know lots of Linux people who feel that way about Windows :)
