Double Exposure in AE
hey Guys, need some help with AE expressions… So my goal is that have 1 or 2 lines of expression on Opacity of a picture or solid layer and when you duplicate the layer, the opacity will change automatically. For example, the first layer is 100%, and when you duplicate it, the new layer will be 50% and the next one will be 33% so on….
The expression should be a index one, i am not sure what exactly it is, something like index>1 bulabulabula..Thanks!

Try this:
index*100/thisComp.numLayers;
(assumes all layers are participating)

Thanks for helping me, but can you be more specific for me?
In my workspace, I created 10 layers since I don’t know how to write an automatic expression on Opacity, so the opacity of my first ‘Image Choice_1’ layer is 100%, and I wrote this on ‘ImageChoice_2’ layer: ‘ if(thisComp.layer(“ImageChoice_1”).transform.opacity>=100) 50 else 100; ‘.
How to add your expression(index*100 thisComp.layer) to mine?

I’m not sure why you would need to combine expressions. If you apply my expression to each layer, you should get this for 1 layer:
100
this for 2 layers:
50
100this for 3 layers:
33
67
100this for 4 layers:
25
50
75
100etc.
Isn’t that what you wanted?
