I have implemented a post processing shader in my project using this documentation and im wondering how i would be able to implement multi pass post-processing with that method.
So far ive tried to just use multiple rects, but sadly the first shader just gets overwritten, since godot only writes once into the SCREEN_TEXTURE.
I am using this method instead of the viewport one since i need to get access to the DEPTH_TEXTURE in multiple shaders.

I am now wondering how i could implement multi pass post-processing in 3D while still being able to access the DEPTH_TEXTURE?

Have you tried using a BackBufferCopy?

Multi-pass post-processing is not supported yet: https://github.com/godotengine/godot-proposals/issues/496

Given the implementation complexity, it's unlikely to be implemented in time for 4.0 either.
