I render my impossible pics in PoseRay / POV-RAY. Poser6 crashes with more than 4 characters in scene. I've rendered an orgy of 9 V2, 9 M2, 1 V3 and 1 M3 (twenty characters) in four hours and a half. And both PoseRay and POV-RAY are free softwares

EDITED
POV-RAY is the render engine, PoseRay a program that translate Poser scenes into POV-RAY
