    Hi,

    I have a project on 2019.3.x with URP and the new URP Post Processing enabled with a bloom effect. It works fine on the iPhone with the latest AR Foundation (all packages are in the latest preview versions).

    However the bloom gets applied to everything, including my 3D objects and the AR camera background. What is the best way to exclude the camera background from it? I read that in URP camera stacking is broken so that doesn't seem to be an option.

    Thank you.

    Create a layer for your background camera and exclude that from post process.

    While searching for this issue I found out the following explanation.

    Post Processing works for every object on the scene.Bloom effect in Unity is actually a post effect which means it works after all the GameObjects have been rendered by the camera, and it can't be seperately affected.

    Should I use multiple cameras?

    Hi, I am facing the same problem.
    I am at Unity 2019.3.5f1 + URP 7.2.0 + ARFoundation 3.0.0

    Using multiple cameras (both as Render Type: Base) doesn't work because the second camera overrides everything from the first, in URP.

    So I made the background camera Render Type: Base, and the items camera as Overlay (stacked on the background cam).
    Setting a layer for the background camera and excluding it from the second camera (which has the postprocessing) doesn't avoid the background being affected by the postprocessing.

    I dropped a comment here waiting for solutions: https://forum.unity.com/threads/glitching-with-multiple-cameras-lwrp.592477/page-3

    Has there been a solution to this? I just tried with the 2019.4 LTS version with camera stacking. Does not work.

    I have multiple cameras but bloom is applying itself to every camera. How do I remove the bloom from just one camera?
