This works, but i have to use linear function…

The thing is, i have for example 10 objects, i and want them to all to have the same effect, and that expression works.

But i want to 3 of them, to start the effect at time 1 sec
Other 3 to start at time 2sec
etc

To have a “effect” that they are all uncoordinated.

If i use your function, they will all have the opacity at 0 and 100 at the same time, because the your expression is all based in time.

Sorry, i know i didn’t explained this at the beginning.

Thanks… i’m already using that, but i have to apply this for hundreds of objects, so i really want a “expression” solution… but thanks!
