(Simple?) expression request

[Nateido1]

I think this is "simple" but I'm very new to expressions, and any help appreciated.

I have a group of subcomps that have an adjustment layer with an effect applied (DigiEffect's Damage, but the specifics I don't think matter). I want to control the adjustment layer effect with a "control layer" Adjustment Layer found in the Main Composition. So it looks like this: Main Comp w/ Adjustment Layer w/ DE_Interference, and I want to link all of the tweaks I make to that Adjustment Layer to an Adjustment Layer I created in each sub comp with the same DE_Interference effect on it. I see I can't pickwhip the whole effect to another whole effect, JUST the individual subgroup of parameters, like "Source_Blend" or "Random Seed", etc. Is it possible to parent those sub comp adjustment layer effects with the control adjustment layer effect? Thanks.

In CC you can copy an effect with links via expressions.

But yes, you can link as many of the parameters as you would like. Once you've linked it in one comp, copy and paste that layer to the rest of the precomps.

Pull the timeline panels apart so that you have both your main and precomp's timelines visible, twirl down the effects for the layer and then pickwhip from the values you want to change in the precomp to the corresponding values in the main comp.

Ah ok, thanks Szalam. It seems like it'd be nice to be able to simply parent an effect with an effect of course, but once the individual paramaters are all parented, it seems an easy job from there. Thank you!
