This shader is deprecated and should only be used with the Standard shader.

This shader can be used to render materials with complex index of refractions. The Standard shader can compute the Fresnel effect for dielectric materials like plastic and glass based on the refractive index of the material; however, metals have a more complicated Fresnel reflective curve that also depends on another parameter called extinction coefficient.

You should not use the Complex IOR shader with the Standard Surface shader. The Standard Surface has the complex Fresnel built-in when the metalness is > 0, using the base and specular color.




Presets of different materials. The custom mode allows you to define a custom setting. By clicking on the Edit button, the selected preset overrides the Reflectivity, Edgetint, and n, k fields, allowing you to refine the settings.
