We don’t currently have a complete course specifically addressing your situation but I think I can piece together some relevant training:
– Creating Grass: @jlampel teaching how to create realistic particle-based grass
– Creating Plants: Another one by Lampel in the same vein about plants.
– Procedural Sand Dunes: While sand dunes are a specific landmark, you’ll find the process can be manipulated easily enough into mountains or rocky terrain.
– Procedural bodies of water: A chapter in our Shader Forge course about various bodies of water. It’s pretty in-depth so here’s a simpler version from another course (a pond).
– Shading Gemstones / Ice: Since you mentioned caves you may be interested in a gemstone shader.
–Shading Lava: Another specific landmark that teaches a lot of flexible techniques that can be used to achieve other landscape features.
I hope this helps carry you further down the road with your project!
PS: I’m glad you found the tropical island live stream series. There should be some decent info in there about generating and managing a landscape in broad terms.
