I hinted at it before, I wanted to share 1K and 2K packs for Vanillaccurate but I didn't want to redo the whole packs from scratch as I did with PiXXL, because VA was designed with a native 512x resolution.
I decided to use a professional AI upscaling tool to create those high res packs instead. They don't look as good as a native design but it's still pretty good.

The point of those packs is to fill the gaps when using PiXXL. As PiXXL aims to support blocks from 1.18 onwards (PiXXL Legacy nonwithstanding), the earlier blocks are covered by Vanillaccurate but the 1K and 2K res were missing.
Of course it's not possible to load full 1K/2K packs right now, so it's mainly for showcasing purposes. But you can hand-pick which blocks you want to use from PiXXL and Vanillaccurate to use in your specific world.

There is hope that someday a mod will bring a whole new way of loading textures into Minecraft, so it's not limited by the fact that all textures are loaded at once, all patched in a single atlas. Check out Continuum Graphics who are working on such a mod, called Focal Engine.
