Metallic BSDF

The Metallic BSDF node is used to recreate the appearance of metals.

入力

F82 Tint

Base Color

Color of the material when viewed straight on.

Edge Tint

Color of the material when viewed at a 82° angle.

Physical Conductor

IOR

Refractive index per color channel. This is the real part of a complex refractive index, scientifically denoted as n.

Extinction

Extinction coefficients per color channel. This is the imaginary part of a complex refractive index, scientifically denoted as k.

共通

Roughness

反射のシャープさ。0.0で完全に鋭角になり、高い値で滑らかになります。

Anisotropy Cycles Only

Amount of anisotropy. Higher values give elongated highlights along the tangent direction; negative values give highlights shaped perpendicular to the tangent direction.

Rotation Cycles Only

Rotates the direction of anisotropy, with 1.0 going full circle.

Compared to the Glossy BSDF node, the direction of highlight elongation is rotated by 90°. Add 0.25 to the value to correct.

Normal(ノーマル)

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

Tangent(タンジェント)

陰影に使用される接線。何も接続されていない場合、デフォルトのシェーディング接線が使用されます。

Properties(プロパティ)

Distribution(分布)

使用するマイクロファセット分布。

GGX:

GGX マイクロファセット分布

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.

Fresnel Type

Models for describing the metal's appearance, by specifying the apparent color or the physical IOR.

F82 Tint:

Uses the Adobe F82-Tint formula for the metallic fresnel. This allows for artist friendly control of the color near the edge of the material to simulate a complex IOR.

Physical Conductor:

Accepts Complex IOR measurements from real world metals to replicate a more accurate rendering of metals than the F82 Tint Fresnel type.

Complex IOR values can be found from sources like the Physically Based database for CG artists and Refractive Index nk database.
