A highly detailed and yet low-poly mountain rocks / stoney boulder outcrop with PBR textures. Each individual rock has its own 1k PBR texture set, including Diffuse and Normal maps. A generic 1k texture has been used for the smoothness, bump and subsurface. This mountain rock outcrop/stone formation is only 2944 faces and 2964 vertices. Loads of detail have been saved in the 1k normal files. These mountain rocks look great in Cycles and Eevee. I have saved this 3D model out in the following file formats: blend (native), fbx, obj, stl, ply and dae. This boulder rock model is subdivision modifier compatible.
