Which build do you need?

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

(Formerly Called VanillaBackport: Terralith & BWG Compat)

Adds full Terralith and Biomes We’ve Gone, Nature's Spirit And Biomes'O Plenty support for pigs, cows, chickens, and wolves, making these variants work in these modded biomes

If you need regionsunexplored biomes, i would suggest checking out RU Wolves Compat

Also if you want leaf litter, fallen trees, wildflowers generation, and camels and armadillos spawning in modded biomes, and natures, and warm/cold variants i would suggest Vanilla Backport Compat

Special Thanks to Vykket, Fyoncle and Blackgear for making this datapack/mod possible
