thanks for the reply. I was kind of aware of that. but creating a standalone scroll trigger on the same element, but not on the timeline, works as intended. isn't that kind of the same thing.
The problem I'm trying to solve is, that I have a surrounding scrolltrigger responsible for drawing an animation on a canvas and have certain container appearing synchronized with that, but with absolute values as duration and not linked to the scrubbing scrolltrigger. So my initial idea was to define a parent timeline with scrubbing true, have a tween on that timeline responsible for updating the frames and furthermore add more tweens with scrubbing turned off.
is there any easier solution I'm missing here?
