I've spent a few years on this resource pack, it is pretty much one of my main life achievements, even if there's not too much in here I sure spent a while making sure it was good, but I'm not too sure if it is as of right now and I typically spend a while upgrading things, but the point is- this resource pack is named "main" because it can be active while any version (from 1.17-modern) is available, and even if you have it active without it, the most it'd do is change textures in game and not do anything with the extra files, so you'd be fine regardless.

I've retextured blocks in this, along with mobs, chests, netherite tools (although that might be a different one) and a lot more so I'm not too sure what's here and what isn't. Some of these features require optifine, and the sizes of one block and a couple paintings aren't 16x16, but there's not an option for that here.
