2 layers doing the opposite thing?

[Dan Ebberts]

Set the opacity of both text layers to 50%.

Apply this expression to one layer (adjust the “freq” frequency parameter to your liking):

freq = 2;
seedRandom(1,false);
w = wiggle(freq,50);
if (w>50) 100 else 0

Apply this expression to the other layer:

freq = 2;
seedRandom(1,false);
w = wiggle(freq,50);
if (w>50) 0 else 100

Hi

Could this expression be adapted for other properties, for example butterfly wings in 3D?
[if you key framed the movement of one wing and the expression mirrored the keyframe
and you could use the frequency to increase the flapping?].

Thanks

I wouldn’t do it that way. I’d get the rotation expression set up the way I wanted for one wing (sine wave, wiggle, or combination) and then just use an expression like this for the other wing:

-thisComp.layer(“right wing”).transform.zRotation

(modified for whichever axis you’re using for rotationn)

That’s great, thanks for the information.
