Ancient City Finder Guide & Information
Troubleshooting
Ancient cities sit deep below surface terrain. Check your vertical position in game and explore nearby caverns if the ceiling has not been reached.
When exploring in game, ensure that negative signs on seed numbers and coordinate axes match the values shown in the tool.
Known Limitations
The tool marks the central origin of the city structure. Surrounding hallways and corridors extend outward into cavern spaces that cannot be simulated without chunk generation.
