Frequently Asked Questions
What does ChunkScan measure for each Minecraft seed?
ChunkScan indexes analyzed seeds by nearby structures, spawn biome, nearby biomes, cave features, terrain shape, ocean coverage, island count, biome diversity, edition, and Minecraft version. Every seed is scanned automatically — results are never hand-picked.
Why are Minecraft seeds handled as text?
Java Edition seeds can use signed 64-bit values that are larger than JavaScript can safely store as numbers, so ChunkScan keeps seed values as text to avoid precision loss. You can copy and paste seed values directly into the game.
Does ChunkScan work for both Java and Bedrock?
Yes. Seeds are scanned separately for Java Edition and Bedrock Edition because structure placement and biome generation differ between editions. Always match the edition and Minecraft version shown on each result when entering it in-game.
