While i was making rumpled-paper terrains for a street scene, i began to wonder how one would create a ball of crumpled paper in Bryce... or in any 3-D program, for that matter. Rocks with transparency are interesting, but don't quite fill the bill. What would you-all suggest? i need something to keep my pebbles, broken asphalt, roaches, cigarette butts, trash cans, beer bottles, and dumpsters company.
