I'm trying to assign a motion path to the light rays effect on one of my layers but i can't seem to find a way to do it and google has turned up nothing. the problem is the effect needs to be on a certain layer in order to make the effect look right but i don't want the layer to move i only want to affect the centre point of the effect. i can assign key frames and animate it to move in straight lines but i need it to move in a curve and there seems to be no way to alter the motion path or assign it to one on a null layer.
This is driving me crazy so any help would be appreciated.
Sure you can do all those adjustments - in the layer view. that's how it always has been. alt-click/ double-click the layer. To link it to a Null, simply use a pickwhip expression.
I was able to to use the motion path in layer view but for some reason there doesnt seem to be a way to use the pick whip on the light rays centre property which is frustrating.

You alt-click the stopwatch for the center property just like any other time you want to create an expression...
