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. Product: Arnold render for Cinema 4D Company: Solid Angle Website: The popular render engine has finally reached the growing CINEMA 4D user base and does so with style, stability and a blisteringly fast interactive preview. Arnold for Cinema 4D (or C4DtoA) provides a bridge to the Arnold renderer from within the standard Cinema 4D interface. 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.
The problem I’m having is that I can’t get any interactive feedback in the IPR aside from moving the camera. However my processor is pretty weak compared to my GPU (rtx3080) so I want to use it in GPU mode. Over the years I have been collecting IOR (Index of Refraction) values I can find for use in 3d rendering applications. I’ve been trying out Arnold render in C4D for the past few days and I think the CPU mode is brilliant.
