Modding newbie interested in creating a HD texture pack

[MegaCatYu]

I've recently taken an interest in modding, and there's this VN called Another Code R which I want to create a texture pack for.


I know how to dump and replace textures, but I have a few questions.

What would be the best way to replace a font? I'm mainly worried about keeping consistent letter spacing.

Is there an ESGRAN model that's particularly for upscaling watercolor-esque textures? The game's art style heavily relies on these, so I want to preserve the effect as best as possible when upscaling.

As an AI network I can recommend ESRGAN Pytorch,
with other Ai I always have problems with the alpa channel.
for repeating textures, the seamless mode is very handy.

Model differ very much, just try some out,
https://upscale.wiki/wiki/Model_Database
Here you will find suitable upscaling models.

To add onto what Venomalia said, if you are on windows and wish to leverage AI, I recommend Cupscale.

Thank you Venomalia and iwubcode, I will look at Cupscale and the upscaling models you sent.
