Bedrock Calculator

Find your exact overworld coordinates by reading the bedrock.

Bedrock Calculator is a client-side mod that determines your precise X/Z position from the bedrock pattern at the bottom of the world. The lowest bedrock layer generates in a deterministic pattern, so a small sample is enough to recover where you are — no need to track coordinates manually in survival.

How it works

• Open the in-game GUI and mark out the bedrock vs. air blocks on the 6×7 grid.
• Fingerprint the pattern against the world's bottom layer.
• Recover the seed data and sample the noise.
• Project the result into exact overworld coordinates — instantly.

Everything runs locally on your client. Open the interface any time with the /bedrock command.
