MtlX Roughness Anisotropy VOP node

On this page

Calculates anisotropic surface roughness from a scalar roughness/anisotropy parameterization.

Parameters

roughness

float

anisotropy

Amount of anisotropy, range [0.0, 1.0]. An anisotropy value above 0.0 stretches the roughness in the direction of the surface’s 'tangent' vector. An anisotropy value of 0.0 gives isotropic roughness. The roughness value is squared to achieve a more linear roughness look over the input range [0,1].
