I see now a bunch of new addons with animations.
Tell me if this will not work.... Have the missiles as part of the main model, rotating as on a turret. When the HAWK fires, the missile part of the model swings down into the ground as an animation, and the firable missle model is placed and off it goes.
I know it is possible to have animated objects on turrets, since you can turn out on the top of a tank.
Also, would it help if each of the three missiles were classified as separate weapons?
