The start of an environment ^^
To see more of this environment, materials for example. You can find those on my artstation:

Any feedback or constructive criticism is always welcome of course!
I got a lot of inspiration from my favorite artists for this environment.
One of the final shots of the environment. The progress behind it and more shots can be found down below!

Here is a quick blockout I made in UE4 for the environment:

The first image is an improved version of the rock where I added more detail. The one under it is the sculpt where I sculpted the main shapes.

So the ground material is using displacement for smaller rocks, and the cliff walls have some smaller (mesh) rocks scattered at the base to help blend the ground and rock walls togethern, visually?
Is the ground a landscape actor, or is that a mesh?
No, I didn't use any displacement. It's just flat ground materials on a landscape mesh. I put down some small pebbles and rocks I sculpted in Zbrush though. The cliff rocks indeed have smaller boulders and rocks scattered around the base yeah, that's right
The ground is just a landscape actor where I sculpted a bit of height variation.
