When you say ...

"This should replace all ior, cauchyb, nk files, ... parameters."

... does it mean it will be an option or the other parameters will
vanish into the void? I'm asking cause I don't wanna loose IOR etc.

Just curious tho. :P :D ;)

It means that glass will accept an arbitrary IOR, either defined through RGB colors, a single float, a nk file, ... ditto for metal and all materials using IOR.

The basic infrastructure is in place.
I'll now add new Fresnel classes to store SPD representations of IOR and start to create new Fresnel textures.

The constant texture gives access to a dielectric with constant value over the spectrum.
The cauchy texture gives access to a dielectric with a varying value across the spectrum parameterized using the cauchya/cauchyb parameters or the index/cauchyb parameters (index being the mean value over the visible spectrum).

The new sopra texture allows loading of sopra nk files.

"luxpop" and "preset" fresnel textures have been added giving access to loading of luxpop files and old metal presets respectively.

Only major fresnel textures to implement are "mix" and a color based definition.

The color based definition is now available through the fresnelcolor texture.
