I'm messing around with Unity 2017's post processing tools while making a 2D game that benefits from the parallaxing effect using a perspective camera. Please note that the game is mostly made using sprites.
Now, I have a playerGround, a backGround and a foreGround. I wish to blur the background and foreground only but not the playerground. I'd like to know how to do this as playing with the focal length didn't do anything, everything receives the same blur amount regardless of the distance from camera.
