    N and K nodal inputs for IOR values

    Here is a 2015 Nodal setup that allows N and K values to be converted IOR of real materials like metals, plastics, crystals, glass, liquids, etc. This node setup does require one plugin that one can get from here. (

    The values can be converted from this website ( per color channel. The wavelength values per channel should be: 0.65 for Red, 0.55 for Green, and 0.45 for Blue. I have these also stored in the description line of the compound node. Also there is a roughness setting just for fun. The samples attached show some of the compounds I tested with. They are in the node setup.

    Example: Pick Aluminium - place .65 in the wavelength value. Place the results for N and K red channels. repeat for green and blue.
