I created a terminal with an interior for FSX. The glass is semi transparent and made in GIMP. After I applied the texture to the window area and loaded it in sketchup, everything looked fine. However, when you go inside the terminal and look through the window, jetways and aircraft disappear. Once you get outside of the terminal, the jetway and aircraft reappears. I think this might have something to do with the semi transparent texture but how do you fix this? In addition, looking through 2 layers of the semi transparent glass causes one of the layers to disappear as well.
