Given that I actually prefer P5 SR3 to Poser 4 I almost didn't ask this but... "A full soft body dynamics engine"? Do you mean the cloth room, or something much more interesting & useable that allows Poser characters to have "soft" or "fatty" parts pf their bodies (cheeks, bellies etc.) so that movement and/or gravity help give much more "reality" to animations? Because I've missed how to manage that if it's in place ;(
