Quote - stewer? May I ask you why you used 20 as the IOR in the fresnel blend node in your gold shader? That's not even close to the real IOR of gold (which is 0.47). If we can't use the real IOR why do we have an IOR input? Or is it multiplied somehow?

It was pulled out of thin air. I was to lazy to find out the actual IOR and just put a number in there that didn't look too terrible.

IMHO, the fresnel effect on metals in close to negligible anyway - at least not nearly as prominent as it is on non-conductive surfaces.
