Full Screen Shaders in URP?

[Lo-renzo]

Are you using the 2D Renderer? If so, there’s this example here

GitHub - Unity-Technologies/2d-renderer-samples at 21.2

Look for the Heat Haze Overlay scene. It showcases a shockwave-like effect - heat distortion. It uses the _CameraSortingLayerTexture.

See this post for some details on how to get it up and running:

@Lo-renzo

In Shader Graph declare a new Texture2D property, make sure its reference is _CameraSortingLayerTexture, and UNCHECK Exposed. This tells ShaderGraph to get the global texture by that name.

Set up your 2D Renderer Data asset to generate the _CameraSortingLayerTexture.

The sprite that makes use of that Shader Graph must be set to render AFTER the _CameraSortingLayerTexture is created (set it to a later Sorting Layer) or else you’ll get the last frame’s colors which will look very odd.
