What is the scientific name of colored rough gloss in materials ?
I am not a scientist in materials, but I think to see in some materials a rough colored gloss, like in satin, sports-wear, fabric for tent, hair, fibers, and maybe some stones, pearls, shells, skin, fish.
I make those with a diffuse shader ( = already rough glossy , right?), with a rough glossy ( 0.3 roughness) colored without Fresnel ( anyway if I should put Fresnel here, Fresnel effect almost disappears ? ). And on top of that I put a colorless, sharper reflection which has than Fresnel.
I used to call it metallicness, but I suppose that is a wrong name. So what is that rough colored gloss I think to see in those materials ?
Often we talk about the translucency, transparency, etc of a material, but this colored-rough-gloss property, I don’t see people talking about it.
