The black film used to improve the appearance of the destination sign is a GI/1E improvement. It can be changed by moving the lighter window (shown by a red arrow) over the black window (shown by a blue arrow), the location shown thus:
And as for the "Brandenburger Tor patterns", I had to leave them out because it would actually ruin the passenger experience of looking out for landmarks from the window.
Also, one important element of 3D modelling is texture mapping. In Max 9 I had to use a function called Unwrap UVW to map the texture to the model properly, to solve the ash problem. I'm not sure what 3D model program you're using to , though. The bogey hasn't failed if it does show up properly. It may be just the texture coordinates need to be tweaked. In 3D modelling, a texture is mapped onto a mesh using vertex coordinates, like this:
