it would be great if the reflection/refraction override (both in the global, as well as in the local material specific) were broken up into two separate overrides, one for reflection and the other for refraction. I have come across several instances where this would be desirable.
and on those same lines (actually, I’m not sure that this is possible…) if there would be some sort of reflection/refraction exclude, where you could pick which objects get reflected/refracted in a particular material or object. If it’s possible, it would be awesome
