This is a fantasy, nordic-inspired stone that I originally sculpted in 3D-Coat in Hi-Poly for 3D-printing purposes (being an impenitent wargame and roleplayeing game player), then retopoed and textured. The model comes with a 4K set of textures for glTF format, that are named image_0 (with metal/rough in the same texture, blue channel being for metallic and green for roughness), Image_1 (normal map) and Image_2 (albedo). If you are a Blender user, you may prefer to load directly the .blend file, which has all resources packed in. For other applications, if they support glTF, you may prefer this format which will save the hassle of importing the textures by hand over other files such as .OBJ or .FBX.
