I've recently encountered this problem: I have a dynamic moving shot and want to add a light ray on a lantern in order to enhance it. I tried to track the position of the lantern, targeted it with a null object and then tried to parent the center of the light ray with the position of the null object, but now I cant reposition the light ray anymore... any tips?
What do you mean you can't position it anymore?
If you pick-whipped the position of the center of the light rays to the null object, simply add +value on the end of your expression and you can adjust (and even animate) the center.
