Setting Transforms For Other Layers
I am working on a comp that is going to be automated (with scripts) to open a text file and make new text layers for each line in the file. I then have text layers whose text sources are defined by the new layers’ index numbers (1 through 3).
I’ve gotten that far, but now I need to hide the first 3 layers, either by changing the opacity to zero or to somehow make them invisible to rendering. This will all run on a website with aerender though, so I need this to be done in the script, as there will be no user interface to AE.
So how can I set the opacity to zero of layers 1-3 based on index through a script?

You’re talking about a script, not an expression, correct?
With a script you could do something like this (assuming myComp is a variable referencing the comp):
for (i = 1; i <= 3; i++){
myComp.layer(i).property(“Opacity”).setValue(0);
}Or this:
for (i = 1; i <= 3; i++){
myComp.layer(i).guideLayer = true;
}Or this:
for (i = 1; i <= 3; i++){
myComp.layer(i).enabled = false;
}If you are talking about an opacity expression, it would just be:
index <= 3 ? 0 : value

Perfect, thanks so much! I am running it in a script; I think I’ll use the setValue(0).
