Blueprint for Post Process GI and shutters closing

Hey VaSSiLi, thx for writing your solution, I do understand the basic concept but i’m afraid i don’t understand most of the steps, is there any chance for a screenie of some sort? Might be easier I think, I’m not fluent in blueprints and i can’t rly seems to find a way to get them all together. I think i will manage the timeline though and will proly import my animation there.
