This is so close to what I´m looking for. Probly just need a few tweaks that i can´t figure out.

I have about 20 different layers of photoshopped stars in a comp, and I want them all to be twinkling randomly using expressions. I want them to both twinkle and fade in and out randomly like real stars appear to do, not as strobe lights, which is what happens when i try the wiggle() or random() expressions. I want the twinkling and fading to slowly pulsate at random intervals and i also want the duration of each “pulse” to be randomized.

If I apply this expression to all 20 stars, they all pulse in and out at the exact same times with exact same shine and duration. The “Shine” effect is a good look, but it is a hassle to keyframe each of the 20 stars differently to make it appear convincingly random.

I would really appreciate a swift reply to this! Thank you so much for any help!
