Java · 1.21.3Know what you’re looking at.
Versions: the listed Java generation models are supported through 1.21.3. Newer releases, custom world presets and datapacks are not modelled. Choose the version that generated the chunks you’re exploring; upgraded worlds can contain several versions.
Terrain: Overworld relief is estimated from generation noise. It does not show individual blocks, trees, builds or exact elevations. Biomes are sampled at Y = 63. Nether and End use the biome view.
Java structures: biome-checked predictions. Terrain can prevent a structure from appearing. Spawn is estimated.
Bedrock: Overworld biome reference uses the shared 1.18+ generation model. Structures use separate Bedrock placement calculations with a biome filter; these predictions have not been checked in-game. Nether, End, strongholds, trial chambers and trail ruins are unavailable in this mode. Slime chunks use Bedrock’s seed-independent calculation.
