here's a theory- create a choppy terrain, as above..duplicate it, and shrink the 2nd copy slightly. Texture the larger terrain as above, then texture the 2nd with a cloud texture, and position it a hair just above the first..;) I dunno..I think it might work..give it a shot.

I wish I'd said that.. The Staircase Wit
