    I'm using multiple cameras in my project (URP). One camera only renders the UI layer and so everything else is culled, but according to Frame Debugger, VFX.ProcessCamera is called for every camera and updates some visual effects (apparently camera sorting) even if the camera has no way of seeing those. Is there anything that can be done about it? Or is this a bug?

    I have the same problem.
    Will it affect performance?
    I would like to know if there is a way to deal with this.

    Hi, yes it's a known bug that some VFX commands didn't get correctly culled per camera. This is fixed in 2022.2

    @JulienF_Unity Is there any chance to get a backport for this fix on 2021.3 LTS? Also, any possible workarounds, or a link to GitHub to see how to patch this is an older project?

    Hi.
    I see that this has not yet been fixed in 2022.2.0b13, but is it already addressed in this version?

    If you mean 2021.3 LTS, definitely no. I have a VFX-heavy project with 7 cameras, and VFX seems to be taking up insane amounts of time.

    Thank you.

    We confirmed this bug in 2021.2.19.
    I also updated to 2022.2.0b13 and confirmed it.
    It appears that this bug has not been fixed yet.

    Hi, we are currently working on this, the fix takes a little more time than expected but is still planned to be fixed in 2023.1 and backported to 2022.2
