Have not yet upgraded to P5...is the FireFly render engine much better than the default P4 renderer? I mean in terms of output quality... I realize that FireFly supports additional features (displacement mapping, raytraced shadows, etc.), but do you guys really notice improved output quality? It's hard for me to know which posted images have been rendered with what engine...so I'm just wondering whether the FireFly renderer has distinct characteristics. Any P5 users still using the default P4 engine? If so, why? Any and all opinions appreciated. Sincerely, pdog
