Nordic tundra environment. For this scene I played around a lot with static Quixel assets like rocks and ground while mixing it with my own foliage and tree creations.
I created the vista mountains in the backgrounds by taking height map data from google and generating nanite meshes which worked pretty good optimization wise as background. Clouds were made using Unreals own volumetric cloud system and the sky is usingthe Sky Atmosphere system. Enjoy!
