I have a model of a structure within a structure that displays properly in Revit 2012 but does not display properly in Revit 2013. See the attached PNG.
The inner structure is set to have transparent walls so the equipment inside it can be viewed. In RST 2013, the transparent inner walls show on top of the solid outer walls, as if the outer walls as well as the tanks were transparent. In RST 2012, the display is correct - you can just see a bit of transparent wall through the opening in the solid wall.
Make sure your graphics drivers are up to date. I think this revit city thread might be talking about the same thing.
Any transparent surface shows up through any surfaces in front of them UNLESS you have ambient shadows turned on.
Does the problem still occur when you turn on ambient shadows?
Thanks - using a Quadro 2000 and the driver is newer than the certified one. Toggling Hardware acceleration (per the Revitcity topic) has no effect. Turning on shadows, and then turning them off again fixes the problem. Curious that it's an issue in 2013 and not 2012...
This certainly sounds like the problem described here, which should be fixed by a display driver update:
Are you getting your drivers direct from the nVidiasite or from Windows Update?
I would go with the driver from the nVidia site, they seem to take a while to get over to the Microsoft (Windows) listing.
