Thanks Adam. It's a duplicated terrain, separated on the y-axis. One with holes punched through it and another with 'Red Fractal' from the Basic Textures in the Materials Lab - applied to the bump channel of a simple white 'snow' texture. Sorry about the size. :( I compressed it to jpeg, but I never checked to see how big the files were that are posted here. They all take a long time on the 28k connection I use most of the time. And thanks Crescent, I have put it in the Bryce Gallery, too. Noel
