Problem with night textures

I have repainted Meljets 777-300 in bare metal. The textures look good during day, but the night textures show up as the day textures without the reflectiveness. This is very noticeable because of how I painted the bare metal( Scanned a piece of aluminum foil and than "cloned" the textures/colors on to the paint kit, plus painting darker pieces on the textures, to have the look of different shades of metal) Is there a way to change this?? I have attached two shots to show what I am talking about. You can either respond to the forum or email me at [email protected]
