Classic Ore Patterns

Turning the ore patterns back to the old ones, including Copper Ore and Deepslate Ores!

Aquatic Add-on

Changing the textures of all kinds of fish & aquatic mob buckets, as well as the blue ice, to match the old style of Minecraft textures better.

Java Parity

Making some old textures consistent with those in Java Edition, including Lava, Peony, Rose Bush, all Nether Bricks, Crying Obsidian, Respawn Anchor, and Lodestone Compass.
