Hi Julien,

Thank you for your reply.

I've tried what you've suggested, but it isn't quite what I was looking for.

I'm trying to get a series of dots (image 1) in different size to blink randomly, much like the example.
Image 1

I did the same set up as shown in the link, but my dots disappear after!!! Any suggestions on how to get the blinking animated effect, that feels like rain drops?


What i did:

Adjustment layer with 3 control sliders:
- Change Seed
- Minimum Start
- Maximum Start

Each dot on its own layer, and applied the following to each:
- Control Slider called " Frame Delay", with the following expression:

seed = thisComp.layer("Control").effect("Change Seed")("Slider");
minStart = thisComp.layer("Control").effect("Minimum Start")("Slider");
maxStart = thisComp.layer("Control").effect("Maximum Start")("Slider");

seedRandom(index+seed,true);
randFrames=random(minStart,maxStart);


- Scale, with the following expression
frameDelay = effect("Frame Delay")("Slider");
valueAtTime(time + framesToTime(frameDelay));


- Opacity, with the following expression
frameDelay = effect("Frame Delay")("Slider");
valueAtTime(time + framesToTime(frameDelay));
