I wanted to make a chasm with cliffs on its edges that is inbetween two peaks of a mountain. I managed to make the two peaks fine and get the rough shape of the chasm but it looks too smooth. I tried adding erosion but it loses its shape. I want it to be rocky and steep but also be flat enough so that I can add a mountainside road on the cliff. Any help?
Use the surface nodes. They are there to add surface details. Erosion handles channels flows deposits. But it won’t give you rock detail.
Something like a fractal terrace or sandstone node and a warp node with a slope mask would probably work.
