I got tired of the hires fix in Forge Neo being completely useless for Anima models, and after seeing an article that appeared to have mitigated the problem, had an AI create a functional fix.

From my limited testing it functions well enough for my purposes. Also from my testing, it may also have a positive effect on SDXL/Illustrious/NoobAI models, but that wasn't the intended aim.

As with other extensions, you can install it by placing https://github.com/Kaybe97/forge-neo-anima-hires-fix.git in the Extensions > Install From URL tab of Forge Neo. Or you can download the ZIP archive here and extract it into your extensions folder.
