Transform multiple layers randomly with one control?
Basically, I’m wondering if there’s an expression or script that would allow me to transform multiple layers randomly with one control–much the way Wiggle Transform will do for groups in a shape layer–so I could have a lot of elements explode out in different directions and with different rotations, and then have them snap back into their original formation, without having to individually animate keyframes. Kind of similar to what a randomize function can achieve in C4D. Kinda.
Thanks!

These two scripts can be used to assign random start positions.

Here’s my method. Use an expression on each transform control with the following basic formula:
underlying value + (unique random offset * shared control)
The shared control impacts the amount of unique random offset each transform gets. When it’s 0, no transforms are made and it remains at its original underlying value.

I’d use something like this, then precomp it, and use a time remap. This will use the initial value as an end point, and assign a random start point.
moveDuration = 1;
wiggleAmp = 100;
wiggleFreq = 3;seedRandom(index,true);
w = wiggle(wiggleFreq,wiggleAmp)-value;
startPos = random([thisComp.width,thisComp.height]);
ease(time,inPoint,inPoint+moveDur,startPos + w,value)“|_ (°_0) _|”
