This 3D model accurately replicates the natural rock formations of mountainous and hilly terrains. Based on a gray-brown base color, it finely presents the edges and textures of the rocks, weathered cracks, and the granular feel of the surface soil. It retains the authentic texture of rocks found in the wild, and set against a minimalist black background, it highlights realistic natural ecological features. It can be used for outdoor scene construction, game terrain creation, and other settings, combining scientific ecological accuracy with visual appeal.
