Aye, not to contradict you at all LeeEvans, but if you do a search for, "Radiosity", "HDRI", or "True Ambience" in the Bryce forums here, you will find hundreds of images ranging from Pumeco's style to Ornlu's style, meaning newbie work all the way to our in-house ridiculous Brycologist. There's really nothing mysterious going on TO figure out... He hasn't re-written the Bryce renderer, merely found some features he thought nobody knew about. That said, there's nothing wrong with his ideas, OR his enthusiasm! I enjoy those things myself, and I hope we're not discouraging. But at the same time, calling something "Profesional" means that it's a PROFESSION, meaning you make money off of it. I can't see how Pumeco's product will help us do anything we couldn't already do without it... Perhaps "Bryce GT"...?
