### Maxwell IOR data

Is it possible to use that in luxrender materials? Here's an example of the copper ior file from maxwell render. http://pastebin.com/PN7Njq85

That looks like a SOPRA style nk file, so just use the "sopra" fresnel texture and specify the filename, and then use the texture for the "metal2" material (in blender set "metal type" to "fresnel texture").

even if the material is a non metal, the ior file can still be used? http://pastebin.com/2tHGaey7

Yes, you'll need to use glass2 for this, and assign the texture to the IOR of the interior volume. See http://www.luxrender.net/wiki/LuxRender ... als_Glass2 and http://www.luxrender.net/wiki/LuxRender_Volumes for more details.

Make sure your file has an empty line at the end though, otherwise it may fail to parse.
