mountain landscape 3d model

Create a vast, expansive natural landscape inspired by a serene mountainous environment, featuring rolling green hills, rocky terrain, and towering mountains in the distance. The scene should include detailed grassy fields, scattered rocks, and natural elevation changes, with a clear sky and soft atmospheric depth to enhance scale and distance. Ensure the environment feels massive and open, extending as far as possible in all directions. Do not include any humans, animals, or living creatures—focus entirely on the land itself with a clean, untouched, and peaceful atmosphere.
