Toggle a layer’s opacity (or other property) on/off to preview effects?
Hello, I did a search for this question, but didn’t see any promising results; my apologies if this is AE 101.
When working on a project, I sometimes find myself wishing I could briefly toggle a 0% opacity layer visible, to work on its parameters/effects at that specific frame.
What I end up doing is set the opacity to 100%, thereby creating keyframes which I later have to clean up again. Opening the layer itself in the viewer allows me to preview effects individually, but not the whole stack, and not in conjunction with the other layers.
Thanks,
Adrian -

You can use the eyeball to the left of the name to turn that individual layer on and off, if thats what you are asking. also you can “Solo” a layer by clicking the box to the right of the eyeball. On another note when doing effects in your effects control panel you can click the F/X to the left of the name and turn individual effects on and off.
Hope this helps.

I’m looking to do that, but with a layer whose opacity is 0% at that frame. I want to see it despite that and without messing with keyframes of that property. Unfortunately neither the ‘Eye’ nor ‘Solo’ can achieve that to my knowledge.

Not that you really want to do this, but you could do a relatively simple expression on the opacity. Just add a Checkbox Control effect to the layer, then give your opacity this expression:
if (effect("Checkbox Control")("Checkbox")==1) {
100;
}
else {
value;
}
Now when the box is ticked, the opacity will be 100%; when it is unticked, it will return whatever value the keyframes dictate.

Alright, thanks for the tips. Too bad this isn’t realized natively in the GUI. The workarounds offer little advantage over creating/deleting keyframes; both things take up time and have to be cleaned up afterwards. I’ll keep doing it as usual, things could be far worse!
