How to change camera gamma/set post process settings

I am trying to set the post process settings for my camera component within my character class. I get access these properties via “get post processing settings”. When it comes to setting them everything is blurred out. Is there some kind of bool that needs to be set within the project settings in order for me to dynamically change these settings?

Thanks.

Alright, if anyone wants to dynamically change any post process settings from the character class, make post process settings node. With it selected go over to the details and select the fields you want to change. Then, from the camera component it self drag out a set post processing node and connect the make post processing node to this.
