Hi!
I was looking the refractive index info website and I don't know which value correspond to RGB wavelength to use it with complex ior shader. I only see one value for N and K:
Someone know how can I get this values with this website? Thanks!

Nope, you just have to get the n, k value for each wavelength one-by-one. So type in 0.65, than you get the n and k for the R channel (first coordinate of the vector in the preset), than type in 0.55 for the G, and so on.
Thanks Peter! now I understand it clearly.
So, If I want to make a new preset (for example a preset from Boron) I need to multiply or divide the N value (2.3465) by 0.65 to get the R wavelength? I feel that I don't understand it clearly yet.
The presets in the complex IOR shader uses 0.65, 0.55 and 0.45 micrometers as the R, G, B wavelengths.
