Overlapping canves_item shaders

Godot Version

Godot 4.2


I want to overlapping my canvas item shader
I use color rect for it
I want if i have two color rect and they have different shades they can effect each other
For example one color rect make screen invert color and another one make a wave effect on screen and i want a inverted color waving screen

You’ll need to use a BackBufferCopy node.

See the examples here: https://docs.godotengine.org/en/stable/tutorials/shaders/screen-reading_shaders.html
