Important Notes

  • New Worlds Only: Existing chunks will keep their original terrain.
  • Overworld Replacement: This datapack replaces vanilla Overworld generation and may conflict with other terrain-changing datapacks.
  • Performance: Chunk generation can be slower due to the increased world height. A lower render distance is recommended.
  • Distant Terrain: Consider using Distant Horizons or Voxy.
