Three single mountains perfect for finishing your environment. I created these mountains in Gaea 2.0
4k Textures Base, Normal, Roughness, EXR Displacement
If you do not want to use EXR displacement maps, use the included OBJs.
Optimized OBJ Meshes High poly (1 million verts), LOD1 (600k verts), LOD2 (300k verts)
I recommend playing with the roughness maps in your application of choice, perhaps adding or subtracting from its value. Normal maps are not required, but are included anyway. OBJs do not come with material setups.
