World Utils Mod – 1.12.2 – Manipulate The World in Certain Ways

Some of the commands include:

• Remove duplicated entities.
• Remove scheduled tile ticks.
• Replace blocks with another block (or with air, which of course is also a block) in the entire world.
• A setblock command, which (only) works in unloaded chunks.
• An inspectblock command, which shows block and TileEntity NBT data currently saved in the chunk data on disk
• Remove all entities by name from the world files.
• Remove all tile entities by name from the world files.
• Rename entities.
• Rename tile entities.
• Remove non-existing block entries from the block ID map (= clean-up after removing a mod)

Chunk Wand:

• Allows changing entire chunks in the world, or just importing biomes from a different world. The alternate worlds that are used as the source are stored inside the worldname/alternate_worlds/ directory. The mod also keeps track of all the changes to chunks and stores that “database” in the same directory.
