Hello!
I made a landscape material with 4 layers, cliff, snow, dirt and grass. I want to be able to add a physical material for each layer, so that with snow, I can have snow effects when you shoot it, and with cliff - rocks, etc.
The [documentation here][1] says it’s possible, but it doesn’t go into any detail on how to do that.

Can anyone tell me how to do that?
