Hey to all,
I was wondering what would be the best way to put up a Specular-Fresnel term.
For example, I currently have my Fresnel term mutiplied with the Blinn/Phong term, before being fed into the Exponent and etc. which is lastly being added to the final output, so that at glancing angles, the fresnel kicks in, but only parts being hit by the light (specular term).
I have read at the same time some documentation which say Fresnel should just be standard added to the Specular term, which strikes me as odd.
Anyone have hints in that area? Would much appreciate it.
