Then, you can try with this:

and you can set the frequency, just like a wiggle.

Cheers,
François

frequency = 2;

seed = Math.floor(time*frequency);
start = seed/frequency;
stop = start + (1/frequency);

t = key(numKeys).time;
seedRandom(seed,true);
rand1 = random(t);
seedRandom(seed+1,true);
rand2 = random(t);
easing = ease(time,start,stop, rand1, rand2);
valueAtTime(easing);

Hi!

You can try with this expression:

François

t = key(numKeys).time;
valueAtTime(random(t));

Well, a lot of people have been trying to access MaskPath via expression (including me 🙂 ), but the only things you can do with expressions is grabbing another MaskShape, and/or MaskShape at a different time.

But there is no direct way to access individual Vertex (or even bounding box itself).

The reason is “maskPath” is an “opaque data union”. And the only way to access individual parts of this union is via Scripting or Native plugins.

No good news, sorry…

Hi!

I’ve just developped a plugin that does what I think you’re looking for:

But there are other solutions too, like:

…look for MaskVertexExpression which is free.
