Upgrading from 2021.3 to 2022.2 broke stacked PP effects

Hello,

We recently upgraded from 2021.3.0f1 to 2022.2.15f1. We have a URP PP stack that affects our UI and Gameplay cameras differently. Obviously top-level cameras stack on cameras below it - we have blending and other workarounds in place for that, nothing new there. But when we upgraded, only the UI cam PP effects were working. (I’ll post our setup below). We eventually figured out two separate things that “fixed” this:

  1. Checking “Stops NaNs” on the Gameplay camera (not recommended for permanent use by Unity)
  2. Removing UI Camera from the Gameplay cam’s Stack (not an option since then UI doesn’t render at all, obviously)

When we debug for NaNs, none show. It’s also telling that that checkbox isn’t required if the UI cam is removed from the stack. Has anyone else encountered an issue like this? Any help or insight is greatly appreciated.

Ok here’s our setup:

We have 3 global PP volumes: Default, GameOnly and UIOnly
(NOTE: obviously “UIOnly” isn’t really true, since it stacks on cam’s below it. But it’s for fx that are doubled from the “GameOnly” volume, to give UI it’s own look. Specifically here it gives UI less bloom than the Gameplay cam)

Here’s the Gameplay cam’s setup:

Here’s the UI cam’s setup:

I’ve filed a bug report with Unity and it can now be tracked here Unity Issue Tracker - Post-processing is not visible when Camera Stack is used
