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_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	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.
