In addition to redrawing the picture to remove mosaics in RPGM games, is there any other way to remove mosaics? For example, Unity has a plug-in that can remove mild mosaic.
TLDR: Using AI and editing the images further is the fastest way without compromising quality.
In Unity it's easier because the assets are uncensored, the devs just enable a plugin to censor some assets or part of them. This game has censored originals from the get-go, so you have to do more than just disable a plugin.
There's AI's with questionable results (tried that), and they won't look so nice when used on animations too.
Best way is to use AI and edit further the images, polishing them enough so they look good enough to justify the reason to decensor in the first place.
