Smooth my wiggle!

[Navarro...@adobeforums.com]

Hey all!

I am wiggling a Null position as an emitter for Particular. However, the resulting wiggle is pretty jaggy.

I found Dan's smoothing function:
temp = thisComp.layer("Null 11").transform.position.smooth(1);
[temp[0], temp[1]]

But it only make my streaks smaller, not smoother. They are just as jaggy as before.

The problem isn't with wiggle() per se, it's that wiggle is getting sampled too infrequently to give you a result that is representative of the motion of the emitter. The emitter's position is being evaluated on every frame, but the emitter is moving so much between the frames that a lot of information about the motion path simply never gets sampled.

The only way to get that information onscreen is to reduce the frequence of the wiggle. This will necessarily make your particle animation run slower (you'll also need to increase the lifespan of your particles by in inverse proportion to compensate). Then you'll have to nest your particle layer and the emitter light and use time remapping to speed up the animation.
