Here’s iClone‘s official presentation video for the major GDC 2012 event. Including a glimpse of 3DXchange 5’s Bone Mapping (at 2:37). Also a look at the pipeline for taking an iClone character into the free Unity game-engine with animations (from 2:45).
I’d guess it’s possible that use in a commercial Unity game might require a payment by the game developers to Reallusion, since the actual models and animation files would effectively be being redistributed? Perhaps an arrangement along the lines of Muvizu’s sensible approach to commercial use, asking for payment only once substantial money has actually been made?
