I guess it depends on what kind of effect you are looking for, but I don't think that the specular highlights created by Swift3D are going to generate the effect Off Top is trying to achieve. If I am mistaken, then Bill is right that you can get something to that effect by checking the specular highlights option, but that alone is not going to produce a very spectacular effect. It's true though, that you might not have to do it frame by frame. Depending on the animation, you may be able to use a motion guided tween.
