I dont know much about DS, but I can say this...a scene I was trying to render in P5 but was unable to after several tries (it seemingly got stuck on "adding objects", I let it run 58 hours the last time, then I finally canceled the render), rendered in DS in 8 hours 46 minutes...I dont know why it wouldn't render in Poser 5 but would in DS...

Say what you mean and mean what you say.
