I`m trying to create a glass box with objects inside, basically a display case. On another thread here I found the setup for a realistic glass material, however the result seems very dark. The relation between reflections and the objects showing through seems ok, but the wall behind is completely white and the glass seems quite grey. Imagining a glass box in real life it seems to me it should be almost transparent. I used a simple cube and added the glass material to it. Is the cube rendered as a solid glass body or are only the planes making up the surface rendered as glass. And how would my setup have to look like for either situation (1) solid (2) glass walls. If this dark grey glass is not due to some mistake I made in the setup, is there a way to make it ligher or more transparent in any way?
UPDATE: I found out that I have to use the solidify modifier to have walls instead of a solid chunk of glass. I now have 2mm thick walls, however the glass still seeems grey. the main change seems to be the reflection which has gotten stronger.
