Absolutely true, Zhann. That's the one thing I hate, that I can't export my Bryce constructions into other programs -- or share them with anyone except another Brycer. And, Erlik, of course I'm right in general. It's just in the specifics that I'm usually off the mark. As to having lots of booleans to work with, it's really a matter of organization and structure ... another reason I started writing my book (in the dim past of 2001). I've got 1,000s of cubes and spheres in most of my structures, but there are some simple tricks for keeping track of them and for selecting just the ones you want at any one time. Also different ways to organize materials and textures that the books never discuss. (I can see I'm going to have to post a chapter or two as tutorials on that. I may suck at some things, but I'm a whiz at organizing stuff.)

Could be worse, could be raining.
