No matter what I do, I can't get DOF to work with any camera type, any scene, even in the ones I download from Unreal's learning section. I can make the entire screen blurry or the entire screen clear, but absolutely no deviation between a foreground and background, where some things are clear and others are blurred. I really just need to differentiate between a few things up front and a few in the back, so I've been trying to achieve a similar effect with post processing, a plane with a blurring material or a UI panel but nothing has worked so far. Post processing has no effect unless it's unbound (I know that's not right and it's not supposed to, I've used post processing in the past to only effect particular areas, but I can't get anything to respond or show any effect of post processing regardless of location unless unbound is checked and it's applied to everything in the scene), the UI doesn't seem to work in any scene setup (only appearing after hitting "play" for game mode, which I'm not doing, I'm directly rendering a video based on my scene) and none of the plane materials I've tried have worked (either because of the post processing limitation or because, after I set it up how tutorials suggested, it didn't blur anything or work). No matter how I set post process up, using DOF there does nothing, not even blurring the whole scene, regardless of whether it's unbound or not. I don't know how to fix the DOF issue and I am perfectly willing to use a workaround, but after spending all week on this, I really don't have a solution, and I'm running out of time. Any and all advice would be appreciated.
