Ground, M-15

SoilFree seamless PBR texture

Dark loamy earth built from soft lumps and fine crumbs, with damp patches going darker and dry crust going paler. Muted pebbles of two sizes are pressed in, and they are a little smoother than the soil around them.

    Normal

    Fine surface direction. OpenGL format, green channel up.

  • Soil roughness map

    Roughness

    White scatters light into a matte finish, black keeps it mirror sharp.

    White is bare metal. Black is everything else.

Where soil works

  • Garden beds, farms and paths
  • Forest floors and trenches
  • Terrain blend layers

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.
