Glossy BSDF

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

Entradas

Color

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

Rugosidad

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.

Rotación

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.

Anisotropic rotation on 0.25 (90°).

Normal

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

Tangente

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

Propiedades

Distribution

Tipo de distribución de microfacetas a usar.

GGX:

Distribución de microfacetas de tipo GGX.

GGX con dispersión múltiple:

Toma en cuenta múltiples eventos de dispersión entre microfacetas. Esto produce un resultado que conserva mejor la energía, aunque en algunas ocasiones podrá ser percibido como excesivamente oscuro.

Beckmann:

sólo en Cycles Distribución de microfacetas de tipo Beckmann.

Salidas

BSDF

Salida estándar de sombreador.
