How do I thin the atmosphere so that I don't lose all my background detail. I want see the skydome's clouds. I've included my before and after with the current material room settings.

Is it me or you? I don't really get it. I guess the top pix is the "after" pic? The bottom is the "before"? Not sure about this but maybe simply reducing the Density might work. But I imagine you would have tried that.? ! Is there a reason for using a "Dome"? What would the reason be? A large area in use for a game or what? Is it just for a foggy atmosphere/ clouds? Have you adjusted the dimensions of the "Dome" You can do Fog without a Dome object. Anyway, I'm sure others will be of much better help than me. :)
