How do use Post Process with a Trigger Box to activate?

I NEED HELP . HOW DO I MAKE IT WHEN PLAYER COLLIDES WITH TRIGGER BOX ITS ACTIVATING POST PROCESS AND DESTROYS AFTER LETS SAY 3 SEC ?! HELPPPPPPPPPPPP

Hello,

I have created a simple setup that can accomplish what you are looking for.

First, you need to ensure that your Post Process Volume’s Enabled box is unchecked, which means it will begin without being enabled. Then, create your trigger volume. Go into the Level Blueprint with the Post Process Volume selected, and right-click and create a reference to your Post Process Volume. Then do the same with your Trigger Box, but instead of creating the reference, add OnActorBeginOverlap. Finally, drag out the pin from your Post Process Volume reference and set enabled to true, add the delay that you’d like, and then set it back to false. Here is a screenshot that shows what your level blueprint should look like:

Feel free to ask for clarification or if you have any questions.

Have a great day,

Sean Flint
