DaForce, You DaMan! I added the glass objects back to the GI solution and checked Refractive Caustics in the GI roll-out and it seems to have resolved the issue. The correct amount of light penetrates the surrounding area around the glass shelf now. Render times seem higher then they should, but perhaps that's because I have fresnel refelctions on. I feel better now - Thanks again . Do you have any other Glass related tips to share with me?

Thanks - Dave

hehe glad you got it sorted.

Rendertimes will of course be higher than what you had before because its not calcing the glass and its reflections.
Using fresnell falloff wont really affect rendertimes that much compared to normal reflection. probabaly faster infact.

If you want to color the glass have a play with fog... set the color then lower the fog value to something you like.

Apart from that glass is generally fairly simple

Yeah, the next trick is to get your reflections to look good. Set your reflection value to white and click fresnel. Unlock the fresnel IOR button, and set the value to about 2.2.

Nice tip Clif - Thanks. Didn't even realize I could unlock that IOR value. Cheers!
