Referencing the layer index of another comp?
Hey guys,
I have a comp with an image layer. I am going to nest this comp (call it A) into another comp B. Then i wish to duplicate instances of comp A in comp B. So far so good. However, I want to adjust the position (lets say X values) of the image layer in comp A based on the layer index value of comp A in comp B. Does this make sense? If so, is it possible?
If it works then with every duplication of comp A layer, the image will have a different position. I can do a simple expression on Comp A layer and this will move with every duplication. However, i dont want to move comp A’s position in Comp B, but the image in Comp A only!
Cheers!

You can only get something like this to work if you duplicate Comp A in the project bin, give each copy a unique name, and bring them all into Comp B. You can’t do it by simply duplicating the Comp A layer in Comp B.

Dan,
So you are saying that i need to add an expression on the position value of the image layer in comp A and then duplicate this in the project bin? If so, what will this expression look like?
Thanks

Let’s say you want each copy to have the image 10 pixels farther to the right. You could add an expression like this to the image layer:
idx = comp(“Comp B”).layer(thisComp.name).index;
value + [10*idx,0]Dan
