Shade has by far the best renderer with raytracing, pathtracing, radiosity, GI, distributed rendering (on more than one machine), etc. Best of all, through the included PoserFusion you can directly import Poser figures/scenes and reneder them in Shade. It also offers options to render in QuickTime VR and animation. Shade 8.5 is discounted 50% for Poser users at $99.99
