Hi Experts!

I really need Your help about this already annoying thing.

When using the pick whip, through comp wide, (I made a control panel on the main comp, with different controls on an adjustment layer) It doestn't work from 2 or 3 comp level deep. It seems that the datas dont get to their destination. Sometime it does.
I tried also to make a "bridge" : on each comp level I made an adjustment layer to pick whip in chain, but nothing changed.

I hope I could tell it clearly. :)

Is there any effect/switch that cause this,or is it a bug, or just this is the way it should be? :(

Thank You the answares in advance!

Have a great day!

Zoli

If your expression looks like this...
thisComp.layer("Some layer").effect("Slider Control")("Slider")
... then it won't work across comps, because it's always looking in "thisComp" for the layer.

If your expression looks like this...
comp("Some other comp").layer("Some layer").effect("Slider Control")("Slider")
... then it WILL work across comps because you are explicitly identifying which comp to find the layer in.

Yes, I checked it.
The expression looks like this:
comp("Anim").layer("--=Control panel").effect("decades")("Slider")

It was made by AE, because I pulled the pick whip from the animated-one to the slider (locking the "effect control" window on the "--=Control panel" layer), so I didn't wrote it manually. And it was working for a while, for some project savings.

Thanks for Your thoughts Walter ... any idea?

Perhaps there is a difference in time that you need to account for?

comp("Anim").layer("--=Control panel").effect("decades")("Slider").valueAtTime(x)
