RPR_MATERIAL_NODE_MICROFACET_ANISOTROPIC_REFLECTION

Usage

Microfacet reflectance with anisotropic rotation. This allows surfaces like brushed metal. The direction of anisotropy is dictated by the rotation, and effects the microfacet distribution.

Parameters

Input Name Type and Range Brief Explanation
RPR_MATERIAL_INPUT_COLOR color Color Reflection color.
RPR_MATERIAL_INPUT_NORMAL normal Vector Normal direction used for shading.
RPR_MATERIAL_INPUT_IOR ior Float Index of refraction, usually 1-5.
RPR_MATERIAL_INPUT_ROUGHNESS roughness Float 0-1 Reflection roughness.
RPR_MATERIAL_INPUT_ANISOTROPIC anisotropic Float -1 to 1 Anisotropy amount, forwards or backwards.
RPR_MATERIAL_INPUT_ROTATION rotation Float in radian Rotation of anisotropy around UV direction.
