Bedrock Pattern Finder

Bedrock Pattern Finder

A client-side Fabric mod for Minecraft 1.21+ that finds world coordinates by matching bedrock floor patterns. Useful for recovering lost coordinates, seed verification, or locating places when only the bedrock layout is visible.

Features

• 1.18+ Worldgen Support: Accurately computes bedrock distribution at Y=-60 using the modern RandomSplitter math.
• 16×16 Grid GUI: Simple interface to click and recreate the pattern of the bedrock blocks in front of you.
• Multithreaded Search: Scans chunks in the background. (Note: Very large search radii like 1000+ chunks can still cause frame drops while the search is active).
• Persistent Inputs: Automatically saves your last entered seed and search radius across sessions.
• Client-Side Only: Runs entirely on the client and works on multiplayer servers, provided you know the world seed.

Usage

1. Open the menu via /bedrockfind or /bedrockfind gui.
2. Enter the world seed.
3. Set the chunk search radius (e.g. 100).
4. Look at the bedrock floor at Y=-60 and fill in the grid:

• Black (Empty): Wildcard / ignored block (can be anything).
• Gray: Bedrock block.

1. Click Search Coordinates. Matching coordinates and rotations are output directly to your chat once found.
