Hey guys

I just started developing a 3d fly around game similar to Star Fox 64/Lylat wars. I am having trouble creating a 3rd person chase camera to follow the ship. The problem I am having is, that when I rotate the ship, the camera rotates, but doesn't follow behind it. So when you turn 180 Degress, the camera is in front of the ship. I know this is probably a basic error, but i can't seem to figure it out.

Thanks
