RPR_MATERIAL_NODE_MICROFACET_ANISOTROPIC_REFRACTION

Usage

Refractive surfaces with roughness and anisotropy. Adds direction to distribution of roughness for refactive surfaces. For example frosted glass with brushed patterns.

Parameters

RPR_MATERIAL_INPUT_IOR ior Float Index of refraction, usually 1-5.
RPR_MATERIAL_INPUT_ROUGHNESS roughness Float 0-1 Refraction 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.
