Metacreations old line's UI takes the learning curve awards when masters get behind thier render engines. I've seen Bryce renders that rival photographic quality. The super high end apps., when coupled With as seasoned a professional, render still perspectives of future promise, but that still look back to the former MC lineup in retrospect. Bryce has a very nice render engine, the only reason it is'nt held in as high a regard as you or would think it should be in on its own right is because Poser and Carrera are part of its price tag. = )
