hey, glad you got it worked out! i was gonna check on my end but ended up busier than i expected this week. sorry about that.
i also apologize about my nodes being messy... anyways, let me know if there are other troubles i could help with:)
Viewing post in UE4 dither post-process comments
Your material nodes were quite clear. They're much cleaner compared to other graphs I've seen.
The only thing that was tough to understand was how the Dither texture actually worked when the nodes go through the MF_Dither material function as there was no comments within that.
I can see the Multiply-floor-divide to pixelate makes sense, and it uses similar nodes to get the Dithering UV, but how the UV coords translate to how much should dither from color step to another is a bit tough to understand.
Overall, Very happy with the material post process, and when the game is further in development I can show how well the post process works.
