Step-by-Step Configuration Guide

Install Chunky plugin

Download the Chunky jar from SpigotMC or Modrinth. Place it inside the plugins folder and restart the server. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Set World Border

Configure a strict world border using vanilla commands (e.g. /worldborder set 10000) to limit world files expansion. Open the file using the built-in Pterodactyl File Manager editor. Ensure you do not use tabs for indentations, as YAML requires spacing rules.

Set Chunky boundary parameters

In the server console, run 'chunky center 0 0', 'chunky radius 5000', and 'chunky shape circle'. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Run chunk generation

Run 'chunky start' in the console. Monitor progress logs and wait for completion before letting players join. Check the server console panel logs as the startup sequence runs to verify that no error exceptions or missing dependency logs are thrown.

Recommended Configurations and Setup Files

To configure your server files correctly, navigate to the File Manager in your control panel and open the corresponding configuration files. Paste or modify the settings as shown in the configuration block below. These lines help prevent database thread blockages, optimize tick timing performance, and reduce entity rendering overhead on the game host:

# Chunky console commands sequence: chunky center 0 0 chunky radius 5000 chunky shape circle chunky start chunky progress (To monitor ETA)

Pro Tip: Chunk generation stresses CPU cores to 100%. Do not perform pre-generation while players are online. We recommend running the Chunky command overnight. Pre-generating world chunks using plugin utilities (like Chunky) is highly recommended for reducing startup lag during exploration.

Frequently Asked Questions

How big will the world file grow?

Pre-generating a 5000 block circular radius will take up approximately 8GB to 12GB of SSD storage. Ensure your host has sufficient storage limits.

Does this work in the Nether?

Yes. Use the command 'chunky world nether' to switch targets before starting generation.
