Did you make all three textures? Each ship needs a _cl (colour map) _da (data map) and _nm(normal map)
The colour map, you need an alpha layer for the team colour, in the data map, you set metal-look, reflection, bloom and illumination....
the normal map is just a normal map, makes things look like they have raised or lowered bits while the geometry is flat.
Anyway, it looks like something is up with the _da texture as well as your team alpha layer in the _cl
