Expression between 2 layers’s opacity
I have a layer with multi value of opacity. because this layer opacity linked to audio keyframes from another layer. i want to link another layer opacity to this layer opaciry. but i want to have reverse value of opacity from new layer .
for example each time opacity from layer 1 was 1%, opacity from another layer to must be 99%. or each time opacity from layer 1 was 35%, opacity from another layer must be 65%. exact reverse together.
How can i do this?

Perhaps something like this…
myOpacity = linear(otherLayerOpacity,0,100,100,0)

This is probably simplest:
100 – thisComp.layer(“other layer”).transform.opacity
