Tweaks and improvements to the default textures.
For version 22.10
Few of many. Only works with English languages.
To see the PWP number, put on an item frame and hold down Sneak. Fully functional in Vanilla.
Emissive ore borders, suspicious blocks and Ancient Debris. Fully functional in vanilla 1.21.5+
Slightly more vibrant.
Optifine or Continuity required. I will add more, probably.
