This is a Camera shader for Godot 4.3 and above to add distance fog with optional noise, color limiting, and dither. There are a lot of fragmented and partial solutions out there and I wanted to combine various techniques to make an easy to use quad-based shader. Each setting can be enabled/disabled and customized. I have tested this in small maps (100x100) as well as large maps (6000x6000) with no issues.

A 4.2 compatible version can be found within the repository's releases
