AS - thanks for the prompt reply. I don't have a problem with using a terrain as the negative, the problem I'm having is when I try to use a bunch of Bryce cubes (shaped, obviously). I've tried making each one negative then grouping them, tried grouping them and making the group negative, tried adding negative ones individually, yadda yadda yadda. Ackshelly, while I was typing this a lightbulb went off, and I realized something I hadn't tried, then I got interrupted and have forgotten what it was :o(( edit to add - maybe I'll do the unthinkable, and RTFM!!!!
