Activity Forums Adobe After Effects Expressions Null + variance

  • Posted by David Hildreth on October 14, 2011 at 9:10 pm

    I have many elements attached to one null with a change in position.

    I’d like to have all the elements to generally maintain the same movement, but with some degree of variance between them. Is there a way to easily add 10 or 20px of random difference between the position change in each element? I’m not exactly sure where to start.

    Do you just want a random offset? If so, either of these should work:

    maxOffset = 20;
    seedRandom(index,true);
    value + random([-maxOffset,-maxOffset],[maxOffset,maxOffset])

    or,

    wiggle(0,20)
