(Tested and works with unity 2019 and 2022) This post processing menu prefab does exactly what it says. You can import it to your project, set-up the post processing how you want it, and you're done. Instructions are included in the main package folder's ReadMe file, in case you need to know how to change something. My discord is also in the ReadMe, in case you need some help changing anything about it. There is also an Udon Graph and Udon Sharp version included, but the recommended prefab to use is the Udon Sharp version, as it is cleaner and easier to use. I included the graph version, in case someone without coding experience wants to edit the prefab.
