I’ve managed to find a solution and learn what it was I did that may have stopped it from working originally. Keeping roughly the same setup, (1) the issue was that I had passed in my Post Processing Volume BP in instead of the actual volume itself. (2) You have to make a new variable of type Post Process Settings to serve as the mechanism for controlling the settings. Plugging that into the “set” allows you to control any parameter you want at runtime. For a sanity check, it might also be beneficial to complete delete the Post Process Settings Ref and Set and create new versions of them.
