About this project
What does GAROS Performance Optimization - Initial Chunk Generator add?

Prepare Your World Before You Enter It
GAROS Performance Optimization - Initial Chunk Generator coordinates Chunky and Distant Horizons during the creation of a new single-player world.
Instead of entering a world surrounded by unfinished terrain and waiting for distant detail to catch up, you can generate a configurable area around spawn before gameplay begins. Once preparation is complete, the world opens automatically.
Initial generation is optional and disabled by default.

A Controlled Two-Stage Process
First, Chunky generates complete Minecraft chunks around the world spawn.

Afterward, Distant Horizons prepares the corresponding distant terrain, avoiding competition between both generators during the initial process.

When both stages finish, the world opens with its initial terrain already prepared.

Features
- Adds a dedicated Chunk Generation tab to the world-creation screen
- Optional initial generation, disabled by default
- Preset generation radii of 16, 32, and 64 chunks
- Custom generation radius from 16 to 128 chunks
- Configurable generation thread count
- Configurable worker capacity
- Live progress for both generation stages
- Protects the player while preparation is running
- Opens the world automatically when preparation finishes
- Cancels interrupted generation instead of unexpectedly resuming it
- Restores the player’s Distant Horizons settings after completion or interruption
- Includes a one-click Reset to Defaults option
Requirements
- Chunky
- Distant Horizons
