Front Color – The color for the texture when viewed frontally (refraction color).
Side Color– The color for the texture when viewed at a grazing angle (reflection color).
Fresnel IOR– Index of refraction to use when calculating the Fresnel term.
Refract IOR
...
– Specifies the refraction index of refraction for the underlying surface. This is ignored if the surface has a volume shader (the volume IOR is used instead).
Contribute to Fresnel IOR Render
...
Element – When enabled, the V-Ray Fresnel Texture contributes to the Fresne IOR Render Element.
