This can also be mapped to blend between the two different ways materials behave in the real world.Įdge Color for metals, which can be quickly and easily defined with a single color which will be ideal in 99% of cases – but when the ultimate in realism is required, there is the option to use a Complex IOR instead.Īnisotropy correctly affects both reflection and refraction simultaneously. Metalness Workflow which lets you specify whether your material is a metal or a non-metal. Sheen lets you adjust the way a material reflects light, most commonly for fabrics and other materials – think satin or velvet, and how those reflect light differently from non-fabrics at the grazing angles.ģ5 Presets for quick starting points, or to “reverse engineer” good settings for the various parameters for the most common materials you will want to create. It has its own independent reflectivity, its own independent Bump map separate from the Base layer, and Absorption parameters that control how it colors the Base layer beneath it. 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.Clearcoat lets you define a layer of varnish or lacquer for a material – think varnish over wood, or the final coat in car paint. 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.
