How to add a custom post processing pass

[Polarkettu]

How would i go about adding a custom post processing effect. I want to play around with the individual pixels and then send the messed up image forward to the rest of post processing so effects like bloom etc are applied afterwards. Any help or resources would be appreciated

Not sure if that is what you need, but you can explore post process materials that you can apply on post process volume, here:

There are quite a few tutorials on this matter on youtube.
