Script or expression to globally control individual layers in a mosaic animation to create fireworks-like effect?
on Nov 12, 2019 at 6:24:32 pm

Hi. I am working on an animation comprised of a bunch of leaves. They come on, decay, and then disappear. I am trying to animate them like fireworks - so having them come on screen in a stuttering, gradual manner that increases until they're all on screen. Right now each comes on gradually and then stays on, but I am hoping to do it so that a leaf could come on for a split second, disappear, and then come on again and stay on for the main decaying animation.

I would also like for there to be a bit of subtle flicker with the leaves when they're on screen - happening with the leaves individually at different times. Finally I'd like the process of their disappearance to be done in a way similar to how they appeared - in a flickering manner like fireworks as the intensity fades.

I've animated what you see here manually. Are there any scripts, plug-ins or expressions that could help control the types of animations I'm describing in a more global fashion - as in, doing the detail work of fade-ins and fade-outs automatically so that I wouldn't have to animate each layer individually to create the gestalt effect? Hopefully in the end it looks more organic and dynamic than what I have now, which looks a bit stilted. Here's what I have now:







Thanks a lot! I'll include helpers in the credits for my film, Wrought. Let me know if you need any clarifications as to what I mean, or an .aep file to experiment with. ☺

Should the leaves come on-screen randomly, or do you intend for them to show some kind of pattern?

I'm thinking that they will come on randomly as they do in the video, but just in a more lively and dynamic way.
