Corwin, the BT I modeled all in Bryce about two years ago, in Bryce 4 specifically. I modeled it in sections and brought it home on my camera's SmartMedia card, 64 MB at a time! I see what you're saying, Pogmahone, although since I intended it to be water I probably wouldn't have seen that possibility! Good call, I'll try to make it distinctly mud or water in the next render.
