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, a live chunks/sec 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 that keeps the world running while it's open, so you watch generation happen live:
  • Dashboard — progress bar with live chunks/sec rate + ETA, pause/resume/cancel, and queue.
  • Tasks — run, delete, or edit a task in its own form (name, dimension, shape, center, radius).
  • Schedule — build rules with hour/minute sliders and clickable day toggles; pick the task from a list that shows each task's details.
  • Settings — engine, throttle, auto-pause, scheduler, timezone.

Notes

• Requires CodxLib 1.1.0 (or newer), and works on Fabric, Forge, and NeoForge.
• A map view of generated chunks is planned for a future update.
