I was inspired by dandelO's recent work with his atrium pictures, so I just had to download the model and play with it myself. This version was rendered without raytraced objects enabled. I can't decide if I like the texture in the model due to this being off, or the overall better quality if I enabled raytraced objects. I'll just have to play some more and decide eventually.
