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));

Hello Stephen,

Thank you for your respond. I would actually like to create something similar to
https://www.underconsideration.com/brandnew/archives/tate_2016_logo_animation_2.gif

I have seen Trapcode, but it’s a paid plugin hence I do not have it. Any other suggestion on how to achieve the following?

Thanks,
Tian

Would like to create a dot animation similar to the gif attached. (https://www.schoolofmotion.com/blog/random-expression-after-effects) Would like them to feel like rain drops

But i’ve got 500+ dots of varying sizes. I’ve tried to import them as individual layers so that I would be able to apply a random expression to the layers. However, it just causes my after effect to hang.

Is there another way to animate the dots individually?

Thanks,
Tian
