I think the screenshots explain it all. The one from BTB is what it's supposed to look like. The models were made in SketchUp 6, if that helps. I think I know the problem - there is texture#.jpg, and texture#.png. How these can get swapped I don't know, as they are different file formats. The tram was not made by me, and they are the jpeg textures. I prefer PNGs, to be honest. I need a solution, not a suggestion as to what the problem is, because I already know. I just don't know how to fix it.
