Finding structures gets easier once you know what the generator is actually looking for. Filter the built-in biome rules here, then use /locate in a test world when you need to confirm a pack or server setup.
Structure & biome lookup
Use the dropdown to narrow these ten configured destinations. Optional #c: tags depend on the installed modpack and may match zero or many biomes.

Default placement checks
| Rule | Default or source behavior |
|---|---|
| Common structure set | 40-chunk spacing, 30-chunk separation |
| Village exclusion | 10-chunk exclusion zone around village structure-set candidates |
| Flat-ground requirement | Footprint sampled at corners, edge centers and middle. Difference must be at most 4 blocks. |
| Height check | Generation center terrain height must be below Y 250. |
| Structure selection | One weighted set of enabled structures, not ten independent spawn probabilities. |
Why am I not finding it?
- Check whether the relevant structure is enabled in
config/masterswordand whether its bundled data pack is loaded. - Explore new chunks; changing structure configuration does not regenerate already explored areas.
- Check the listed biome tags. The Nayru Shrine definition relies entirely on optional
#c:is_cold/overworld. - Some candidates are rejected for terrain roughness, height, village proximity or jigsaw placement failure.
- With cheats, run
/locate structure mastersword:temple_of_timeand substitute the other registered IDs as needed.
Structure weights are relative and do not override biome requirements or terrain rejection. Avoid treating them as exact per-chunk percentages.
