Flickering Vignette

Hi there.
I would like to add a subtle vignette layer on top of a scene.
I would like the vignette to flicker, as if the scene was being “lit” by flickering light.
Any idea how I can make the opacity of a layer…flicker randomly without having to hand animate it?

Thanks

JavaScript could be used with the hypeDocument.setElementProperty API to change the opacity of an element.

Maybe the values in the templage need to be changed, as it’s not quite a pleasing animation, but it shows the general idea.

Hey! That’s Great!
Definitely a start.

Thanks so much!
