Glossy BSDF

The Glossy BSDF node is used to add reflection with microfacet distribution, used for materials such as metal or mirrors.

Inputs

Color

Color of the surface, or physically speaking, the probability that light is reflected for each wavelength.

Roughness

Input for the surface roughness resulting in sharp to blurry reflections.

Normal

Normal used for shading.

Properties

Distribution

Microfacet distribution to use.

Sharp

Results in perfectly sharp reflections like a mirror. The Roughness value is not used.

GGX

GGX microfacet distribution.

Multiple-scattering GGX

Cycles Only Takes multiple bounce (scattering) events between microfacets into account. This gives a more energy conserving results, which would otherwise be visible as excessive darkening.

Beckmann

Cycles Only Beckmann microfacet distribution.

Ashikhmin-Shirley

Cycles Only Ashikhmin-Shirley microfacet distribution.

Outputs

BSDF

Standard shader output.
