Oops, I forgot to add, the only problem I can see with this method is, the whole mesh becomes one object (which can be a pain for the likes of windows/canopy's) but all it requires is to break up the mesh beforehand for any items that can't be satisfactorily textured, and import seperately. I suppose the other method would be to use texture masks and just alter the objects properties, though admittedly I am not too sure on this method. Anyway, hope this helps to point any others with the same problem in the right direction.
