Image Effects don't effect UI.

Questions & Answers

Hi there, I’ve been stuck on this for about a few hours now. But, really the case is easy to solve! Just when i change the UI Canvas to Screen-Space camera. But, that then effects the UI itself too. I can’t do certain things with the UI, (My example, dragging it. )

I am just figuring out what to do, I’m on a test scene on trying out UI, and here’s what I mean.
The backround is a simple Image Effect, but those test windows don’t manage to add to the image effect, anything that’d help? My camera itself is just all the way it’s originally is. The only thing set up for the camera, Is the Image Effect. If this helps, I doubt it will! But the image effect is a Old TV Screen. Distortion and such. But, if there are any suggestions, It’d be great enough.

Have two cameras with same parent object. Set second camera to Dont clear and set flags so it has only the UI layer. On the main camera set the flags as they are but uncheck UI.

On second camera, set it to orthographic if you are using deferred rendering.

On camera with only UI layer set, apply your post process effects.

Lastly, your UI canvas object needs the render mode set so it is Overlay camera with your second camera set as the target.

This effectively does your rendering in two stages. Everything but UI on camera1, then UI with post process on camera2.

Another key here is maing sure that both cameras render the same way, i.e Deferred, HDR.

If you get stuck, let me know.
