Quick 2 day project to practice rock sculpting and lighting. "Less is more" approach; tried to create as much detail as possible from just a few meshes and a single material. Really happy with the lighting.

Rocks sculpted in Blender. Base rock material maps created in Substance Designer. Unreal master material uses world-aligned triplanar mapping and various color variation techniques for breakup. I use a couple variations of the rock material throughout the scene with different variations. Vegetation is just 1 bush i threw together with GScatter.
