opacity=time*index
I cannot get the syntax correct. So any help is highly appreciated.
Thanks.Basically–very basic!–the circles will fade in over a few seconds, then when opacity = 100, it should fade out.
Thanks again!

Something like this should do the trick:
fadeInTime = 3; // duration of fade in (sec)
fadeOutTime = 1; // duration of fade out (sec)if (time < inPoint + fadeInTime){ linear(time,inPoint,inPoint+fadeInTime,0,100) }else{ linear(time,inPoint+fadeInTime,inPoint+fadeInTime+fadeOutTime,100,0) } Dan

Yep, it works!
If you wouldn’t mind, taking a second to explain the expression, so that I can learn what’s happening, rather than just copy-paste.
Additionally, I was hoping it would loop this effect too, with some kind of random number, as in fadeInTime = x, where it’s a slider.
Thanks for your patience and help!

What do you mean by loop? Continuously fade in and out? Is the random number is the same for each fade in, but different for each layer, or different for each fade in? How do you see a slider involved in all this?

Thanks!
I think this is correct-ish:
seedRandom(thisComp.layer(“Null 11”).effect(“Random Helper”)(“Slider”),true)
But I’m not sure it answers all your questions, sorry:(
Otherwise, yes — different for each fade in. I was hoping to make one layer and then duplicate it 5 or 6 times. Also slider plus the index, so that layer 1 and layer 2 differ but are still very similar.
There’s also a position expression that I deleted by accident. Very simple though, the position moved time*index.

It’s going very slowly, runs out of memory, and crashes. Somewhere I read the proper order of things, how things should be nested, and I believe I’ve got it all wonky.
Any help is greatly appreciated.
Thanks
