Old Growth Forest
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.
Old Growth Forest simply adds an uncommon Forest variant with large trees. This biome has a chance to replace regular Forests at high enough "Weirdness" values, which is the same generation criteria for Old Growth Birch Forests, Old Growth Pine Taigas and Old Growth Spruce Taigas. Please note: Project is currently in Beta.
