2d renderer, perpective camera and depht of field

Hi all !

We create a 2d sidescroller with several effects and we exploit depth on the foreground and background a lot. For this we use a technique described in an article by gamasutra: https://www.gamasutra.com/blogs/MichalBerlinger/20160323/268657/Combining_Perspective_and_Orthographic_Camera_for_Parallax_Effect_in_2D_Game.php

We use sprite-shape, 2d light and shader graphs on the URP renderer.

Our cameras :
3d camera - perspective (background and depth effects) with some big sprites.
2d camera ortographic - game plan, with colliders, sprite-shapes, 2d lights and various effects with lot of sprites.
3d camera - foreground with some sprites and vfx.

On this stack, we add some various post-process effects.

We would love to add depth of field on this to blur the foreground/background depending on the distance and add awesome depht effect it’s not working with sprite-renderer and camera stacking.

Do you have an idea for doing this?

a little up ^^
Any idea ?
