Cavity Wall Air Gap Transparency

[Leech123]

Morning All i hope someone can help me out here.

I have a thermal Air gap in a cavity wall, however the air gap transparency cuts through the wall behind it and you can "see through" the other leaf which is reality isn't the case. I've tried to show this in my screen grab. I know i can turn off the transparency in the setting under appearance but this doesn't give me the desired look of Two walls with an Air Gap.

Does anyone know whats going on here?

I think its because Revit doesn't draw a texture on the "inside" of a wall. But if you really want this look you can modify the middle layer to be 1mm height in the edit structure tab, by unlocking it and dragging it down.

You could try a different vdeo driver or turn on/off hardware accelleration and see if it helps.
