    I've seen the sample for custom passes and custom post process in 2022.2 b.
    But I can't really understand the differences between the two.
    Can anyone explain to me when to use which one ?

    The first very significant difference is their different injection points during the render loop.

    Green is PP injection point.
    Purple is Custom Pass injection point.

    IMO, custom pass is also more flexible in that it can do more than just full screen effect.

    Which to use depends on your use case. What are you trying to archive?

    Something can be done in both while some can't

    Wow that's a cool graph !

    Thanks for your explanation. I don't actually need to use them right now, but I understand it a little better.
