V-Ray comes with a curated asset library - Chaos Cosmos. They can rapidly iterate, make better design decisions and communicate more effectively with stakeholders working on the project. V-Ray Vision gives users a realistic real-time view of their model as they develop it. With Chaos Cloud Collaboration you can upload your images and image panoramas straight from the V-Ray Frame Buffer and significantly speed up the review and approval process. It’s easy to share work and collaborate with internal and external stakeholders on the cloud. This ensures flawless collaboration between designers and visualization experts. Because Enscape materials, objects, and lights are supported, all design decisions are preserved during the different design stages. 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.With V-Ray 6 it is possible to directly convert real-time scenes from Enscape and make them as photo realistic as possible. 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.

It obviously helps if you know what the correct IOR value is for the type of surface you are trying to re-create. 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
