What does the cascade prop on Reveal components do?

what is the ‘Cascade’ prop for in the reveal component?

(And might it somehow be possible to make the sub elements of the revealed component inherit the animation so it is individually applied, each after a short delay?)

It makes each child of the reveal component appear one after another in staggered timing, so it should be doing what you are saying

I could show you that it isn’t.
Tried increasing duration, delay and dampening.

figured out, that for the staggering to work right now, the reveal component needs to wrap multiple children - instead of a stack:

and about the .mp4 not playing:

it used to play in the past.
(the reveal component(s) has nothing to do with it not playing, cause removing them had no effect.)
