Hi all,
I have a scene with a snow-covered mountain slope. I want to add rocks and boulders to the scene. They're fairly close to camera, so fake stones won't work. I want to use a surface layer shader to show snow build-up on the tops of the rocks, but I can't figure out how to do it. Is it even possible? Any advice would be welcome.



You can make stones by using a compute normal/terrain after a displacement and raise or laterally displace after that.

I've made you a basic file. One surface shader will do, but I added two, just to play with.
