I just noticed that there's a restriction on the input of n and k values in the Fresnel node for the "Custom n,k values" type.
From my research, a solution had already been implemented: Metal Material p4/p33839.
Unfortunately, the limitation to the values "Color"[0,1] is present again
Is there any possibility/chance of fixing this ?
Thank's
PS, does anyone have any information on the "Lux Pop" and "Sopra" files ?
Cheers
