How to Use

Paste your world seed into the tool to locate monster spawner dungeon rooms.

Filter the display by spawner mob category using the sub-feature toggles in the options rail.

Troubleshooting

Dungeons require solid underground stone with adjacent air pockets to generate. If a dungeon is missing, check whether a nearby cavern cut through the room.

Confirm that your world generation options were set to default when creating the save.

Known Limitations

The engine flags candidate dungeon origin positions from world seed algorithms. Spawner cage block entity setup occurs during game chunk creation.
