A collection of nine physically based rendering (PBR) materials focusing on stone and brick surfaces, originally authored in Substance Designer. The pack provides 4K resolution texture sets containing diffuse/base color, roughness, normal, and height maps for each surface. Featured materials include multiple variations of rock walls, clay bases, stone panels, black gravel, and specialized textures like Antelope Canyon stone. A pre-configured Blender file is included to demonstrate the material node setups.
