Adjust Brightness Screen
Hello everyone,
I was wondering if anyone knew how to make one of those Adjust Brightness screens that you see in a lot of games, specifically horror games. I figure I have to use a slider, but I am not quite sure what I am adjusting. Something in Post Processing maybe? Also not sure exactly how to set up the image that is supposed to show.
If you don't know what I mean, here is an example: 
There is a post exposure option in color grading in post processing. Via script, edit the post exposure value to match the slider's.
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.PostProcessing;
public class SetBrightness : $$anonymous$$onoBehaviour {
public PostProcessingProfile ppprof;
public Slider brightnessSlider;
void Start() {
ppprof = transform.GetComponent<PostProcessingBehaviour>().profile;
}
void Update() {
//Access colorgrading option here.postexposure = brightnessSlider.value;
}
}
Attach this script to Camera which should have postprocessbehaviour
https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/simple-lut-adjuster-51762#reviews this free asset helped me make my brightness settings, it has a bunch of camera effects that can be accessed from scripts and that includes brightness.

May be it helps you.
Actually this doesn't work when compiled (test 2019.4.3f1 LTS). Nor does setting the ColorGrading Gamma/Gain. They work in editor though.
