DatapacksJava
Little World Tweaks
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.
Little World Tweaks is a datapack that changes some aspects of the worldgen in Minecraft.
Currently the following changes have been added:
- Diorite, granite, and dirt patches have been removed from most caves
- Andesite and tuff patches are more common
- Dripstone caves generate with granite, coarse dirt, and dirt patches
- Lush caves generate with diorite and calcite patches
- Pointed dripstone spikes are more common
- Trees are generally taller
- Fancy oak trees are more common
- Small jungle trees use the large jungle tree foliage placer
- Jungle bushes are less common
This datapack should be compatible with most mods, but it may not be compatible with other worldgen datapacks that modify biomes.
