What Ive basically got are three slopebased material functions (the layers Im talking about): cliff, erosion and grass. I would like to use tesselation on all of the layers, I just dont know how well the grass would look, and besides that I dont understand how to apply a different heightmap to each layer which supposedly shows where the tesselation is meant to push down or up. Im not sure whats the best approach, pretty much. Either way, the more tesselation the more realism and thats what Im going for.
Ive tried masking (B) the heightmap result of the cliff material function call, but it still affects all layers. I see that I linked to the edit of my post, heres the proper link if the previous didnt work.
