Shockwave Screen shader on 2D URP project

[Lo-renzo]

In this thread someone was wondering about a similar ‘heatwave effect’ and a dev steps in to explain how to step up a _CameraSortingLayerTexture. Unity 2DRenderer Heat Distortion shown in the Unity GDC Showcase 2021 not working

There’s not much documentation of this feature, but the final sections of this page explain a bit. 2D Renderer Data Asset | Universal RP | 11.0.0

Another dev explaining the feature:

2. The opaque texture behavior normally captures the frame buffer after the opaque objects have been rendered. Because Sprites are transparent, I have added something called _CameraSortingLayerTexture for URP 11. It allows the user to capture the rendering of the back most layer to a specified layer into a render texture.
