Glossy BSDF#

Glossy BSDF node.

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

Inputs#

색깔

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

Roughness

Sharpness of the reflection; perfectly sharp at 0.0 and smoother with higher values.

Anisotropy Cycles Only

Controls the amount the reflection stretches the reflection along the surface of the material. A value of 0.0 results in no anisotropic reflections. Higher values give elongated highlights orthogonal to the tangent direction; negative values give highlights shaped along the tangent direction.

This is a phenomenon know as “Anisotropic Reflections” which is often seen in metallic materials.

Rotation

Rotation of the anisotropic tangent direction. Value 0.0 equals 0° rotation, 0.25 equals 90° and 1.0 equals 360° = 0°. This can be used to texture the tangent direction.

Normal

Normal used for shading; if nothing is connected the default shading normal is used.

Tangent

Tangent used for shading; if nothing is connected the default shading tangent is used.

특성#

Distribution

Microfacet distribution to use.

GGX:

GGX microfacet distribution.

Multiscatter GGX:

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

Beckmann:

Cycles Only Beckmann microfacet distribution.

Outputs#

BSDF

Standard shader output.
