Quote - You want to use Fresnel_Blend on every surface where you do reflection. No exceptions. Skin - walls - everything.

BB - wouldn't that stop the reflections from the light originating from the camera angle reflecting off the skin facing the camera?  Or am I missunderstanding this node?

Am I right in understanding that the fresnel_blend acts to diminish reflection toward the point on the object nearest the viewer... so that reflections are not as powerful there as towards the perceived edges of the object?

EDIT: Or have I got that backwards now?

I just stumbled on the thread here which I found very interesting, if perhaps still more confusing... :unsure:
