Thanks to all of you for the encouragement! I'll start working on the tutorial and have it up after the holidays. I'm going to make it "printer friendly" (which means Internet ugly) so you can print it out and follow a printed copy while using Bryce--so much easier than running between two programs on a single screen. There will be a model used, but I'll provide that as a download so we can all concentrate on the lighting. The tutorial will use the model shown in my post, which you can also see in the game ClydeMaze CM-1. It doesn't take up a lot of file space. I'll post a notice on the board here to let you know, so expect it in the early days of the New Year! In the meantime, try out the game: ClydeMaze CM-1 and see how the lighting was used to create an atmospheric feeling. http://www.clydesight.com/clmaze/ As a teaser for the tutorial, did you know that the refraction feature in the materials palette won't work on mesh objects? But, of course, I have a work around-- and a simple one at that! Thanks again for the encouragement!
