Say I put Blender's iconic monkey inside a glass sphere (hollow, but solidified around its exterior). All lamps and camera(s) are outside the sphere. Using Cycles.
What I want to accomplish is for the sphere to get rendered as an "ordinary" glass object, whereas the monkey inside of it gets rendered identical to the way it would get rendered if the sphere around it did not exist at all. (Most of all, I want to avoid the dimming effect the glass would otherwise have on the monkey's (diffuse) surface brightness).
Is this doable? By using the Light Path input in the node editor perhaps? Or maybe by compositing two render actions into a single image?
