So this is a simple idea that should have a simple way to do.
What I'm attempting is, I have my band's logo in vector format.
So I copied it from within Illustrator into AE, which then pastes it as multiple masks, each letter being a mask (2 masks in the case of the letter O, but yeah).
This pretty much already puts me close to what I want.
The intended effect is for each letter to randomly fade in, to finally make up the whole logo.
I'm guessing there's some way to do this with expressions? Instead of having to do an opacity animation on one, then randomly copying it to the other ones by hand?
