I’m still searching for a good procedural material for mountains. I never found a decent one in Vue, and I’m having the same problem here. I remember when I did Scott Brisbane’s Vue workshop that he said they always used photo texture for the rock surfaces. I’ll take that as a challenge.
I’m also using my procedural ground (grass) material here, and I’m reasonably satisfied with that. Plus I’ve added a narrow strip of AP’s grass along the front.
I think I should take Scott Brisbane’s advice. A bit of rock texture over the top of the render adds far more realism than I can hope to achieve with a procedural texture. Maybe I should render out the background mountains as a separate layer just to make the job a bit easier. Then I won’t even have to mask it.
