Its available ! Unreal Engine 4 Retro Dithering
If you take it for free please credit me - Its my first released product ever so please let me now what i have to improve. I am working on the documentation but its easy to use with the standart settings. Just plugin the DitherInstance.material into the blend from your postprocess volume. It can be merged with the 8Bit Pixellize tutorial - i only use gumroad so someone can support my work even if its just 1 dollar so its hosting and donation at the same time.
Its for 4.11.2
