Post-Processing not works right in a scene with two cameres

[mawa]

Hi,
I think this topic might be of interest to you:

Adding a background image that is not affected by the Default Rendering Pipeline post processes

You can do it as you did with two cameras but by blending the last post process of the pipeline with the current framebuffer (which contains the layer image at that point) instead of simply replacing the framebuffer with the result of the pipeline (which is the default behaviour). Here’s a PG that is doing that: You need to set a scene clear color with alpha=0 for it to work as expected.

Else, let us know and meanwhile, have a great day
