Quote - yeah this looks better. is it normal that it looks like the colors are getting desaturated? when the angle changes.
I think so. That is Fresnel reflection - from a very low angle, white light is reflected directly - never changes color.
From a high angle, light enters the skin, gets absorbed by an electron, raising its energy, then it drops to a lower state and emits a photon of a particular color in a random direction. Thus diffuse light is colored, specular light is not.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
