In the cases where there was a range of IOR values for a specific material I have listed the lower value on the left and the upper range value on the right. The next list is the full complete list of hundreds of materials and it is organized alphabetically by material name. The first group contains many commonly used materials. It is for general usage in 3d applications only and not for scientific use.

Please do not take this list to be a scientifically accurate list. You should be able to use these values in many different 3d applications - such as NewTek Lightwave 3d, Blender 3d, Autodesk 3DS Max, Autodesk Maya, Maxon Cinema 4D, Next Limit Maxwell, The Foundry Modo and Strata 3d. RMB will reset the values to minimum and Ctrl+right-click will set the values to their default. This means they will follow 3ds Max’s logic for RMB actions on the spinners. This set has a good variety of metals, and of course, it is more compatible with newer versions of the V-Ray plug-in, such as V-Ray 5, which we recommend you use. Friends interested in using the V-Ray 5 Material Library in 3ds max + V-Ray rendering can use this collection. Choose from a library of over 500 render-ready materials including metals, glass, wood and more. V-Ray 5 Material Library for 3ds Max download. By adding the new VRayLightMix render element, you can adjust lights interactively without rerendering. In V-Ray 6, most V-Ray materials and textures use QT for their GUI in 3ds Max versions 2019 and later. Explore multiple lighting scenarios from a single render. It obviously helps if you know what the correct IOR value is for the type of surface you are trying to re-create. UI Path: Material Editor > Material/Map Browser > Materials > V-Ray. Many 3d applications these days allow you to input actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models. Over the years I have been collecting IOR (Index of Refraction) values I can find for use in 3d rendering applications. Index of Refraction values (IOR) - For use with 3d modeling / rendering and animation applications
