I'm trying to create grass cliffs using the grass bump tile at 0 and then varying normal grass at z 15, 20, 30, etc. I've read over the tutorials and feel I'm drawing the map correctly, but when I finally dragon the bmp all I get are giant hills.

Is there some special script that isn't present in the basic DragonMod11 download to accomplish the cliffs?
