Afternoon I have been experimenting with glass in Gi and am trying to understand why the two inner sides of this glass are too dark. As the rendering recursion level is high at 18, it looks like the glass is simply reflecting on it's self multiple times and ignoring the GI post brightness.
See pic attached. The scene has a constant illuminated sphere as its environment, so the grey cannot be attributed to reflections of other objects Does anyone have a suggestion please for adapting maybe the standard glass shader angle parameter (have tried with a curve controller with no success) or another operator within the glass shader to get rid of the overly grey inner sides ? Hold up a real glass to a white backdrop and you do not get that dark contrast on the inner edges. Many thanks and regards Jason
