What is this?

 

Surface Imperfection maps are high quality textures, scanned from real surfaces.

They are not traditional diffuse textures, but are scans of the subtle imperfections that are shared by most materials, such as smudges, scratches and fingerprints.

The resulting greyscale maps can be used as glossiness, bump, anisotropy, and specular maps, to add those imperfections back into any 3D material
