Alright so let me explain myself a bit here, you know how in games you have those options that define how much gamma there is and whatnot? I was wondering how to do that and how to keep it persistent through all the levels the user has created.
An example of this would be to manipulate say the Bloom shader, by having an option to toggle it on or off an keep it saved.
I'm not asking anyone to code anything for me, but instead to guide me in the right direction.
