Map compatibility and methodology
| Edition | Versions | Dimensions | Status |
|---|---|---|---|
| Java | 1.18.2, 1.21.3, 26.3, 1.19.4, 1.20.6, 1.21.1, 1.21.4, 1.21.5, 26.2 | Overworld, Nether, End | Experimental predictions; coverage varies by version and layer. |
| Bedrock | 26.50 | Overworld, Nether, End | Experimental predictions; coverage varies by version and layer. |
What experimental means
Agreement between native and WebAssembly engines demonstrates consistency between builds. It does not verify every biome or structure in Minecraft. Accuracy depends on edition, version, dimension and layer; some capabilities still await independent validation.
Limitations to know
- Markers predict generation positions; they may differ from /locate and do not inspect your save.
- Bedrock 26.52 is not supported. Dungeons and spawners are not offered while their validation remains pending.
- The map shows biomes at a specific height, not blocks, caves or terrain elevation. Nearby biome search uses approximate 16-block sampling and a maximum radius of 2,048 blocks.
- Player builds, mods and regions generated in older versions may differ from predictions.
How to check a result
- Record the exact seed, edition, version and dimension.
- Record X/Z, sampling height and the requested structure or biome.
- Check the area in the same game version and retain a screenshot. Do not use the map’s own output as independent evidence.
