I am trying to apply distorting effects on many vectors. I tried applying the effect on the parent null but it didn't making any change. the only way I have found it will work is to pre-compose it and work it out from then. is there a way to apply effects on many vectors before pre-composing ?

    Nulls do not render. They only provide position, rotation, and scale information. They can act as placeholders for Expression Controls. You want to use an Adjustment layer or apply the effect directly to the layer. Adjustment layers affect every layer below them so if you decide to use one the same distortion effect would be applied to every layer below it and that is probably not what you want.

    If you want to group a bunch of layers then apply an effect directly to the group the most often used technique is pre-composing. There is nothing wrong with doing that. It does not slow anything down. It is the easiest way to control the render order.
