Change render effects settings?

I’ve been messing around with a few things, and I have found no way to alter the render effects such as lens flares and screen smudging? I’ve tried going into the player blueprint, and changing the render settings there (which I couldn’t find the screen smudges there either) and nothing I altered made any difference?
Does anyone know how I can change these settings? Thanks :slight_smile:

Check the Post Process Volume in your level(or create it if you dont have one already and set it to Unbound to make it global)

Thankyou! Really helped me out! :smiley:
