DitherDown is custom post-processing effect for Unity's High Definition Render Pipeline (HDRP) that dithers and downsamples the entire screen but does not modify color. Based on Kino recolor and Kino Eight.
This package was built in:
- Unity 2019.4.19f1
- HDRP 7.4.1
Tested with
- Unity 2020.2.6f1
- HDRP 10.3.1
Add the package to your project using the package manager's add package from git url option.
Click Edit -> Project Settings -> HDRP Default Settings and add DitherDown to the After Post Process section of Custom Post Process Orders.
In a post processing volume add the Post Processing -> RTWarner -> DitherDown override and configure to suit your needs. Note: Setting the downsample value to non integer values will result in rectangular pixels. I considered removing this, but you might have a use case, so I didn't.
