IOR Values

IOR (Index of Refraction) – The refractive index determines how much light is bent, or refracted, when entering a material.

Thus, using the actual IOR values of materials for 3d rendering allows you to achieve a more accurate representation of surfaces during rendering.  Download the script  drag and drop to your 3dsmax viewport for your quick guide or check the list below.
