Copper PatinaFree seamless PBR texture
Warm copper with verdigris that streaks down the surface the way rainwater would run. Metallic is high on the bare copper and drops to zero on the green, so only the oxidised parts go dull.

Where copper patina works
- Statues and roof domes
- Pipes, kettles and old plumbing
- Fantasy and steampunk props
Getting it into your engine
- Roblox
- Upload albedo, normal, roughness and metallic, then set them as ColorMap, NormalMap, RoughnessMap and MetalnessMap on a SurfaceAppearance.
- Blender
- Albedo into Base Color. Set the other maps to Non-Color and run the normal through a Normal Map node.
- Unity
- The OpenGL normal works as it is.
- Unreal
- Flip the green channel of the normal map. Unreal expects DirectX.
