So the effect I was going for was to have multiple layers slowly begin to blink ON (0 or 100 opacity no in between), then I wanted the ON state to increase in frequency finally having them all hold ON after 5 seconds.

Ok so I’m no Dan Ebberts. Legend. But this is what I came up with and it works and gives me some control. It’s a basic wiggle expression with an if/else function tied to 3 slide controllers.

code:

freq = thisComp.layer(“slider”).effect(“frequency”)(“Slider”)
amp = thisComp.layer(“slider”).effect(“amount”)(“Slider”)
control = thisComp.layer(“slider”).effect(“control”)(“Slider”)

if (wiggle(freq, amp) + control < 1) { 0 } else 100

I’ve been trying really really hard to avoid reading that. It also gives me seizures. But I have the time today to try and learn so here goes.

I’ve also got a 1/2 way decent shortcut working using this workaround:

Thanks Dan you the man.

Dan that works exactly as I requested. Problem is it gave me a seizure. I’m wondering if there is a way to do this same effect using the wiggle expression. So if I had a wiggle with both frequency and amount controlled by a slider with an or/else function to always deliver either 0 or 100?
