I have nice "old movie" postprocessing shader, and I want it to affect on HUD (inventory etc). So I wanted to ask, is it possible to make postprocessing shaders somehow affect on panels? I have a small idea in my head (as I'm noob at shaders, this idea has no point), maybe there is a way, to create one blank panel, set it's layer around 99 (so it will be over all other panels) stretch it to the screen's size and attach "somehow" postprocessing shader?? Thank you for your time! Any kind of help is appreciated!
