《寻物少女》游戏雾气氛围效果 "The fog atmosphere effect in Quest Girl"

I wanted to create a fog effect and initially used the fog feature provided by Godot's world environment, but it didn't quite meet my expectations. Learning to generate fog with shaders online seemed too performance-intensive. Finally, I discovered that adding a depth shader filter directly in front of the camera was simple, effective, and convenient for adjusting depth and color. It's super easy to use!
