Parameters

weight

Weight for this BSDF’s contribution, range 0.0 to 1.0. Defaults to 1.0.

ior

Index of refraction. Default is (0.18, 0.42, 1.37) with colorspace 'none' (approximate IOR for gold).

extinction

Extinction coefficient. Default is (3.42, 2.35, 1.77) with colorspace 'none' (approximate extinction coefficients for gold).

roughness

Surface roughness. Defaults to (0.0, 0.0).

normal

Normal vector of the surface. Defaults to world space normal.

tangent

Tangent vector of the surface. Defaults to world space tangent.

distribution

Microfacet distribution type. Defaults to 'ggx'.
