I had a few exterior elevations (actual design elevations not 3d) of a building that looked great and had nice shadows and materials and everything was wonderful until today when I turned off a couple section marks and a level mark and then the back turned black and the dialog box in Graphic Display Options does not show the background section anymore?????
Now I can't even get rid of the black background!!
I also tried the few options of hardware acceration or not and anti-aliasing but nothing has worked...I hesitate to mention it but i did do a windows update also.
Could it be a direct x problem?
Please check if Revit has the latest update installed and the drivers for the video card is uptodate.
Can you reproduce the issue in a new file?
