Chunky Mod Overview

The Chunky mod for Minecraft is a powerful tool that allows players and server administrators to pre-generate chunks in their world. This helps to reduce lag caused by real-time chunk generation during gameplay, making the game run smoother, especially on large worlds. By pre-generating chunks, the mod improves the performance of your Minecraft server and ensures smoother world exploration.

• Pre-Generation of Chunks: Pre-generate the world’s chunks to reduce lag and improve world loading times.
• Task Management: Start, pause, resume, or cancel chunk generation tasks.
• Customizable Selection: Generate chunks in square, circle, or other custom patterns.
• Real-Time Progress Tracking: Displays the progress of chunk generation in terms of percentage, remaining time, and chunks processed.
• Support for Multiple Platforms: Compatible with Minecraft servers on Forge, NeoForge, Fabric, Paper, Spigot, Bukkit, and more.

Installing Chunky

To install the Chunky mod, follow these steps:

1. Download the mod from a trusted source like CurseForge or Modrinth.
2. Place the mod file in your mods folder if you’re using Forge or Fabric.
3. Restart the Minecraft server or client to enable the mod.

Chunky Commands

General Commands

• /chunky start [world] [shape] [<centerX> <centerZ>] [radius] [radius]
  Starts a chunk generation task based on the selected world and shape. The center and radius can be adjusted.
  Example: /chunky start world circle 0 0 1000
• /chunky pause [world]
  Pauses the chunk generation task.
  Example: /chunky pause world
• /chunky continue [world]
  Resumes a paused chunk generation task.
  Example: /chunky continue world
• /chunky cancel [world]
  Cancels the chunk generation task and removes its progress.
  Example: /chunky cancel world

Selection Commands

• /chunky world [world]
  Sets the target world for chunk generation.
  Example: /chunky world world_nether
• /chunky shape [shape]
  Sets the shape for chunk generation. Options include square, circle, rectangle, ellipse.
  Example: /chunky shape circle
• /chunky center [<x> <z>]
  Sets the center coordinates for chunk generation.
  Example: /chunky center 100 200
• /chunky radius <radius> [radius]
  Defines the radius of chunk generation. For rectangular or elliptical shapes, specify both the X and Z radii.
  Example: /chunky radius 500
• /chunky corners <x1> <z1> <x2> <z2>
  Defines the chunk generation area by two corner coordinates.
  Example: /chunky corners -100 -100 100 100

Miscellaneous Commands

• /chunky silent
  Toggles the display of update messages during chunk generation.
  Example: /chunky silent
• /chunky quiet <interval>
  Sets the interval between update messages in seconds.
  Example: /chunky quiet 5
• /chunky progress
  Displays the current progress of the chunk generation task.
  Example: /chunky progress

Chunky Trim Command

The /chunky trim command is used to remove chunks outside a specific region. This is particularly useful when you’ve pre-generated more terrain than needed or want to reduce the size of your world. It does not affect your builds within the chunks being deleted; it only removes chunks that are no longer in use.

• /chunky trim
  Removes chunks outside your specified region, reducing world file size and improving server performance.
  Example: /chunky trim

Note: Always back up your world before performing this operation to avoid accidental data loss.

Best Practices

• Performance Considerations: Running Chunky can be resource-intensive. It’s best to start chunk generation during off-peak hours or when fewer players are online.
• Backup Your World: Always create backups of your world before making any modifications to avoid data loss.
• Use Chunk Loaders: If you want to prevent certain chunks from unloading, use chunk loaders to keep those areas loaded while trimming other chunks.
• Monitor Progress: Regularly check the progress of your chunk generation tasks using the /chunky progress command to ensure the process is proceeding smoothly.

---

The Chunky mod is a valuable tool for Minecraft server administrators and players who want to optimize their world’s performance. By pre-generating chunks and trimming unused regions, you can greatly reduce lag and improve loading times. However, be cautious when using commands like /chunky trim to delete chunks, and always ensure your world is backed up.
