Setting up Post Processing in Unity
Post processing is a technology that enhances the visuals of a video game. Things like Bloom, Color Grading, and Motion Blur all fall under post processing. Post processing is not enabled in Unity by default, and must be manually installed from within the Package Manager, where all kinds of Unity extensions can be found.
Once installed, a few things still need to be done in order to set it up. First, we need to create an empty GameObject to manage the post processing. The post-process volume component then needs to be added to the object, allowing us to create a profile and begin adding effects to our scene.
Finally, the post-process layer component needs to be added to the Main Camera. This will allow you to tell the game which layer you want to be looking at for your post-processing effects. This same layer should be selected in the post-process volume object.
