The Unity team is planning to resolve this issue. Please submit your use case here to help with proper implementation. Big thanks to Ali Mohebali! ___________________ Having multiple cameras stacked on top of each other with discrete Post Processing effects is currently imposible on URP without complicated work arounds. The most sensible approach to achieve "stacked post processing" would of course be to use the URP camera stacking, with different post processing volumes for each camera. problem: A post processing volume applied to any of the overlaid cameras also gets applied to every camera underneath it in the stack. Since that's not acceptable, the next thing that comes to mind would be to use the same approach people used before in-engine camera stacking was a thing: Render Textures. problem: A render texture does not retain transparency when the camera rendering to it has urp post processing enabled, meaning you cannot stack render textures with post processing since only the top-most one would be visible. I am yet to find any simple approach for stacked post processing, even though this issue and the problems listed above have been brought up multiple times. Here's some examples: https://forum.unity.com/threads/cam...y-different-post-processing-to-the-ui.830778/ https://www.reddit.com/r/Unity3D/comments/i3bmz2/applying_totally_discrete_postprocessing_to/ https://forum.unity.com/threads/ren...rking-anymore-in-urp-coming-from-lwrp.749441/ https://issuetracker.unity3d.com/is...when-post-processing-is-enabled-on-the-camera Any solution that doesn't require advanced knowledge of rendering-related coding would be greatly appreciated, but i see it as an issue that should be officially addressed by unity, since camera stacking was introduced specifically to make stuff like this easier, yet instead made it signifficantly harder. edit: More examples of people facing the same problem: https://forum.unity.com/threads/urp-post-processing-just-one-layer.984712/ https://forum.unity.com/threads/post-processing-on-specific-stack-layer.938363/ https://forum.unity.com/threads/post-processing-volume-multi-camera-question.917000/ https://forum.unity.com/threads/post-processing-different-per-camera.517166/ This is a widespread issue. I understand that URP is still under development, but with so many people looking for a solution and there currently being no work around, i feel like this has to be addressed.
