Property Value

Values can range from 0.0 to 1.0. Default is 0.8.

The roughness defines the quantity of irregularity on a surface, from a perfectly smooth surface (roughness = 0) to highly irregular micro-structure (roughness = 1). This value affects the specular reflection from a mirror-like reflection (roughness = 0) to a scattered reflection (roughness = 1).
