    You can also just use the complex ior osl shader included in vray and enter the n and k balues from regractive index.

    looked the video, seems cool. actually it is for V-Rayforc4d and automatically adjusts the RGB curves in colormapping tab.

    still the vray osl complex ior shader might be easier to use and does the same:)

    Hi as the author of the plugin. firstly thanks for sharing it ! Any feedback is welcome !
    About the history I have made this plugin 10 months ago while vray complexe ior shader didn't exist.
    But you are 100% right, now it's a bit outdated since you integrate complexe ior.

    I want to add is not particular to vray. You can use it in any render engine.
    I only map it to vray using SetDriver/SetDriven.
    I used in Arnold. But again in arnold 5 they implement their own complexe shader.
    For other render engine I don't know them as much, but i'm sure you can implement it simply using a facing ratio and doing a ramp curve for each channel.

    Great to learn every day something new about vray :) But I canĀ“t find the "complex IOR shader(osl)" or am I dumb?
