Please reference the snip below. How do I prevent the components beyond the non-transparent walls and roof from showing through. I have double and triple checked the the transparency setting for the walls and roof in 'Override Graphics in View' and they are both set at '0'. Note these specifics:
Walls: Only the window glass shows through.
Concrete Roof: Everything shows through as if transparency is set at 50%.
Halalujah, updating my NVIDIA display card fixed the problem.
FYI, I first checked for updates using Windows Device Manager and it said my Quadro 2000 display card driver software was up to date. To be sure though, I did a seach via NVIDIA's website at this page http://www.nvidia.com/Download/Scan.aspx
and it recommended an update. It took 15 minutes of downloading and installing, but wow what a difference.
