However, my actual question is if it would be possible to blur elements behind the blur entity on the same 2D screen. As you can see the blur entity only takes the 3D world in account;
My usecase does not have 3D world assets and is purely based on 2D screens. I would love to have the feature of blurring 2D elements. Any clues on how to accomplish this?
That would be a lot more complicated and expensive, as you’d need to capture part of the screen and blur it in between each overlapping UI element that needs blur.
Currently, a scene is captured one, blurred, and used for all following rendering.
If you only need 2 layers (background UI and foreground UI), you could perhaps render background UI to the world, and foreground UI would use a blurred version of that. That’s probably doable.
The script was accessing the camera before the camera had actually set up the scene color map texture. Disabling the blur script in the editor and enabling by script after a small delay fixed the error.
