I think that's one of the (many) great things about having this forum, as a learning device. When I got my first copy of Bryce 5 I had NO IDEA what all the premium settings were for, in terms of effects AA and Rays-per-pixel. Thanks to the work and rendering time of a few dedicated Brycers, I now know what TIR does, and how to set the Ray Depth, and what True Ambience does, and Blurry reflections and on and on! And the only reason to use those settings is if the image calls for it... For example, those awesome renders that AS put up a long while back, showing how the RPP in Premium mode could bring out detail that might otherwise be missed, especially in pixel-level image textures. Great to know, and it's a good thing I don't often render things with that much detail! Sorry to hear that your project wasn't finished in time, but I'm sure it's an AWESOME image, Foleypro, and I hope to see it someday soon!
