ChunkMill

First release

ChunkMill is a fast, efficient, and easy-to-manage chunk pregenerator with its own high-throughput generation engine. Define what you want generated, run it on command or on a schedule, and let it work without lagging the players who are online.

Highlights

• Named pregeneration tasks — define a job (dimension, square/circle, center, radius) once and reuse it. /chunkmill task add spawn overworld square 0 0 5000.
• Run, queue, pause, resume, cancel — /chunkmill run <task> starts immediately or queues behind the current run; control the active run at any time.
• Live progress + ETA — /chunkmill status and the in-game panel show chunks done, percentage, rate, and estimated time remaining.
• Smart throttling — adaptive auto-paces to hold a target ms/tick, or set a fixed chunks/tick. Both cap concurrent work so the server stays responsive.
• Auto-pause while players are online — pregeneration never competes with people who are actually playing.
• Restart-safe — a big run saves its progress and resumes automatically after a restart or crash.
• In-game control panel — just type /chunkmill to open a tabbed screen: a live Dashboard (progress bar + pause/resume/cancel + queue), Tasks (with a Run button and add-task form), Schedule, and Settings.

Notes

• Requires CodxLib, and works on Fabric, Forge, and NeoForge.
• A map view of generated chunks is planned for a future update.
