Yea, you /can/ do it but you probably don't want to do it the way Blizzard has it set up. Just look at the example cliff model files in the art tools.
If you're dead set on making custom cliff models I'd suggest you just make 3d models to overlay on top of the cliffs,which blizzard has resorted to doing as well lately. Example; most of the cliffs on the left and right here are just models inlaid;
Hi, I'd like to use my own models for cliffs in my terrain. how is this done?
Theoretically could be done but I have not noticed any examples of implementation. Try on the terraining forum too?
