It is built on top of a pluggable node system users can extend and customize the system by writing new shaders, cameras, filters and output driver nodes, as well as procedural geometry, custom ray types and user-defined geometric data. The Arnold architecture was designed to easily adapt to existing pipelines. It was developed as a photo-realistic, physically-based ray tracing alternative to traditional scanline-based rendering software for CG animation.Īrnold uses cutting-edge algorithms that make the most effective use of your computer’s hardware resources: memory, disk space, multiple processor cores, and SIMD/SSE units. You can also download and install MAXtoA directly from the Solid Angle website.Īrnold is an advanced cross-platform rendering library, or API, developed by Solid Angle and used by a number of prominent organizations in film, television, and animation, including Sony Pictures Imageworks. When installed, Arnold will be an optional renderer you can choose in the Render Setup dialog. The installation file for MAXtoA is provided in the 3ds Max \plugins\MAXtoA folder. 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.Arnold for 3ds Max (MAXtoA) is included with a default install of 3ds Max, supporting interactive rendering from the interface. 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
