Thats interesting, Rob. I didnt know A;M had a history of RND on this. Wasnt Arctic Pigs and HA:MR GPU based? Some of us are experimenting with exporting obj sequences to Element 3D where a fast render includes realtime AO, DOF, glow, refraction and other goodies... But LACKS raytrace features like reflections and shadows... Which is a huge negative in my book.
