Hi PJF, thank you for your detailed answer. I am using Bryce since years, and I agree: there are still new things to find for me in Bryce. I've tried the array lighing you mention on your homepage, too. That can look pretty good, but the rendertime is almost endless if you have (say) 20 omnilights or more. Ok, that can be done over night, but the arrangement of the lights is a question I still have. Where can I find some tutorials about that theme (e.g. petersharpe has nothing about it or did I overlook it)? I know that shadow mapping etc. is not state of the art, and call me a lamer but: I really like the output. Ralph
