Chunk-Pregenerator Mod 1.16.5/1.15.2/1.14.4 has provided players a new tool: Chunk-Pregenerator. It is a useful device to help you generate your world in a more effective way.

What is Chunk-Pregenerator?
It’s also a server-side tool that contains a few optional client features.
You are able to utilize it in Single-player as well.
Simple to use:
Complete Documentation for Commands
Auto-Completion/Suggestions on command-arguments
Better logging
Optional UI features are easier to control.
Multi-threaded world-generation:
The mod deploys Multiple Cores to create a dimension.
Can set up a world much faster
Multi-World Generation:
Only handle which chunks are to put up the location on the SErver-Thread
You can form multiple dimensions at once.
Playable during the pregeneration process:
Feasible to work while playing
World-Generation is a CPU-intensive mission that can run in the background.
Workable once there’re enough resources.
Enhanced Chunk Generation Checks:
There’s an optimized method to check chunks.
Checking happens quickly but less accurate.
Slower Checks occur off-thread.
Very helpful Memory Management:
Doesn’t shape chunks unreasonably
Manages Memory Usage and clean up leaks
Optimized pregeneration tasks
Retrogen:
Allows Retrogeneration in 1.14 or above
Get that by regenerating the WorldGeneration step
Partly operates on the main thread
Dimension Control (1.16 exclusive):
Offers a manner to disable/enable dimensions
Can begin because dimensions cannot unload on their own anymore
Integrated Profiler:
Own an Integrated UI Based Profiler to display live stats of what’s happening in the realm
Doable on the Networking Thread
Chunk-Pregenerator is a server utility mod. It requires Minecraft Forge and Java 8.
