I'm working on a very similar project---commercial and of significant length. I've had success with Poser 3/Raydream animations but not Poser 4. I also have Animation Master, a terrific program---as good as Lightwave for around 20 times less money---but it lacks in the human modeling category and can't import poser models without a lot of time-consuming decimation. Given my own time constraints and the breakup of Meta, I may just render in poser 4, use Bryce 4 for bgs and do a lot of blue/green screening and compositing in Adobe.
