The PixPack is a work-in-progress resource pack currently made in mind for 1.12.2 (mostly for future mod support), but versions for 1.4 and above will be coming when I finish the main assets.
It's essentially going to be my main Minecraft themed project for a while to help give me something to do that's not working on importing modded blocks into Blender for renders and such or making models, which is to basically to re-theme the default Minecraft textures into something more of my style, renaissance of the SNES, Sega Genesis and PS1 eras while making it resemble the base game at the same time. It'll also help me learn pixel art along the way and give me an excuse not to use the default textures for my renders.
I've been working on and off on this texture pack over the course of 3 or so months, and right now, I'd say it's mostly in a half-finished state. All the vanilla 1.12.2 blocks have been finished, but I've still got to work on items, entities, and possibly the GUIs before either moving onto 1.14 and above and/or mod support, and due to my unorganized priorities, I'm a bit all over the place with them right now, but I hope to at least have some sort of progress on 1.14 or above by August of this year.
