>>43355904So far I haven't seen anyone upscale and clean any of the textures by hand, most people prefer just using waifu2x as it's much quicker.
Pokémon textures in general are pretty damn low-res, even SWSH still uses 512 for a whole bunch of Pokémon (primarily for anything before gen 8 and simpler Pokémon, which I guess is kinda justified in some cases). The most we have is 1024 at max with GO and SWSH, although most are still 512. One fun fact is that this single Sobble texture from a mobile app is probably the biggest one I've seen from Pokémon so far, but the other starters just have the common size.
I'm a sucker for discussing model stuff, so apologies in advance for the tangent haha
