Post Processing using Orthographic Camera

Hey all, I’ve been messing with the Sobel Edge and cel shading for a game and I’ve been running it in perspective. For the game to work right I needed to switch to othrographic. By doing so it no longer shows the post processing! Any help would be greatly appreciated. Thanks

EDIT: Been trying all day to make this work, but decided to go with a perspective camera at a 10 degree FOV. This gets done what I need to but if anyone has any ideas?
