Oh. And one more note. I would definitely go with multiple post process volumes. If you’ll have multiple different objects modifying your global post process volume at runtime, there’s very high risk that you end up losing control which object made current changes. Remember the KISS rule: Keep It Stupid Simple. From ‘code organization’ point of view it’s way better to have multiple PPV’s having their own settings than one global volume being changed by multiple objects (which probably shouldn’t even know about that volume’s existence).
