Option to pause the fill animation while keeping the wave animation

[christopherdavis1]

I'm working on a project where the background liquid "fill" animation will need to be paused by a user interaction. I'd like to have the waves continue to crest, even when the animation is not filling the view.

Have you considered adding something like this?

I'm struggling with the implementation, but if it's easy, could you share some initial direction?

Thanks!

I'm struggling with this too, and I still found no solution. Have you ever found a way to do this?
