bloodsong, You're right... I've had some strange renderings from using boolean differences when dealing with terrains. Just as an experiment, I imported a Poser character, and stuch a cube on her, grouped them, and did the boolean difference thing, and her texture got all messed up, all over, and not only around the cube. Shrug Is this some kind of bug, or is it a RAM problem or what? Maybe I should have saved the picture ans sent it to e-onsoft to see what they have to say. But, not all terrain experiments have been failures, and I've got one scene going right now which will show that, but right now it's kind of lacking unity, so I'm trying to think where to take it next. Soon enough. Bill, yeah, I'll have some stuff ready soon. I'll probably plop the one I'm working on into the gallery this weekend. :) Cheers, Mike
