Chunky Bedrock - Stable Edition
An automated world pre-generator add-on designed specifically for Minecraft Bedrock Dedicated Server (BDS).
Overview
Chunky Bedrock brings the efficiency of Java Edition pre-generator tools directly to Bedrock Dedicated Servers. Say goodbye to lag spikes and unrendered lands caused by fast player exploration. This add-on automatically pre-generates your world in a clean spiral pattern while intelligently protecting your server's CPU performance.
Key Features
- Spiral Generation Pattern: Expands the map smoothly from the center outward to keep memory usage stable.
- Strict 3D Validation: Guarantees that chunks are fully generated by checking deep bedrock layers, sky boundaries, and corner limits.
- Smart Auto-Throttle: Automatically detects server latency drops and takes a breather when the CPU is overwhelmed to prevent crashes.
- Pause & Resume Support: Save and resume your pregeneration anytime using persistent data tracking.
- Automated RAM/Disk Flush: Periodically forces the server to save data to disk to avoid memory leaks during long rendering sessions.
How to Use
For complete installation steps, configuration details, and a full list of available commands, please open and read the README.txt file included in the package.
