Description

Smoothness map (formerly referred to as Glossiness).

Grayscale texture which defines how rough the surface is in 'Metallic' PBR workflows, or the size of specular highlights (glossiness) in non-PBR workflows. This is the inverse of the Roughness map. White areas are smoother and will produce sharp reflections, black areas are rougher and will produce blurry reflections.
