Refraction BSDF

../../../_images/render_shader-nodes_shader_refraction_node.png — Refraction BSDF.

The Refraction BSDF is used to add glossy refraction with sharp or microfacet distribution, used for materials that transmit light. For best results this node should be considered as a building block and not be used on its own, but rather mixed with a glossy node using a Fresnel factor. Otherwise it will give quite dark results at the edges for glossy refraction.

Inputs

색깔: Color of the surface, or physically speaking, the probability that light is refracted for each wavelength.
Roughness: Influences sharpness of the refraction; perfectly sharp at 0.0 and smoother with higher values.
Normal: Normal used for shading; if nothing is connected the default shading normal is used.

특성

Distribution: Microfacet distribution to use. Sharp results in perfectly sharp refractions, while Beckmann and GGX can use the Roughness input for blurry refractions.

Outputs

BSDF: Standard shader output.
