Basin Generation Fix Mod restores natural basin terrain features back into world generation. These rare, small surface shapes strip away the top grass and soil layers of a biome to expose a stony ground floor underneath. Because of an older bug, these patches stopped appearing after the 1.18 update. This mod fixes the issue so you can find rocky clearings across your worlds once again.
Features:
- Restores natural basin terrain features to world generation across biomes.
- Fixes the bug that stopped stony basins from spawning after the 1.18 update.
- Strips away top grass and dirt layers to expose flat stone floors on the surface.
- Adds age and natural variety to landscapes throughout your travels.
- Spawns across many different biomes, including forests, mountains, and savannas.
- Includes rare giant basin variants that create larger open rock patches in plains.
Biomes With Basins:
- Plains and giant plains featuring open stone clearings.
- Taiga and snowy biomes with bare rocky cuts.
- Forests and birch woods showing exposed ground beneath the trees.
- Savannas, jungles, and mountain slopes with natural stony floors.
