1 object in scene has weird lighting

I have this scene and the lighting on the rail I cannot fix.
It is dark no matter what I do… I even deleted it and rebuilt it and get the same result.
Even if I put a lamp directly on it, its shaded… if I crank up the energy of the lamp, the ship turns white but the rail stays nearly the same. If hit a button somewhere and changed somehting, but I cant workout what.

I am taking the top row of vertices from the hull the making the rail from that.

Take a look at the pic and you’ll see what I mean.



Have you enabled Set Smooth? If you have, you might want to use Autosmooth or the Edge Split modifier too.
