You create the animation in poser4 then export the animation as individual obj's. There is a Poser animation imorter for Bryce also available that will do all this for you.. Someone got that url? I got the same importer except it's for trueSpace and it is called truePose. I believe the Bryce one is called "NaturalPose". Try a search on www.google.com
