:alt: Glossy BSDF node.
The *Glossy* :abbr:`BSDF (Bidirectional Scattering Distribution Function)`
node is used to add reflection with microfacet distribution, used for materials such as metal or mirrors.
Color of the surface, or physically speaking, the probability that light is reflected for each wavelength.
Sharpness of the reflection; perfectly sharp at 0.0 and smoother with higher values.
Anisotropy :guilabel:`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 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.

Anisotropic rotation on 0.
- .. figure:: /images/render_shader-nodes_shader_anisotropic_rot025.jpg
Anisotropic rotation on 0.25 (90°).
Normal used for shading; if nothing is connected the default shading normal is used.
Tangent used for shading; if nothing is connected the default shading tangent is used.
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: :guilabel:`Cycles Only`
Beckmann microfacet distribution.
Standard shader output.
