Chunk Pregenerator Tool

Before using please read:

• This tool is currently in beta so expect some bugs! (If found report them).
• supports 1.21.20 and up.
• Do not exit the world while pregeneration is active!
• Please read the usage and fields section before trying to use this tool.

How does this tool work?

• Uses entities and block replacement to forceload chunks.

Usage:

• Make sure you have op in the world you are using and make sure cheats are enabled.
• For now teleport to the area you want to preload (if x and z were 20000 teleport to those coords).
• Run the command /scriptevent searmr:pregen
• A form will display asking for information about what you want to pregenerate, once done click submit and the process will start.
• You will be able to see the current percentage and amount of chunks done via messages sent to the world, you will be told once it is done.
• In some cases it may end up hanging in the very end so just run /reload to stop it.

Fields:

(Goes over the fields in the form).

Dimension:

• Determines what dimension to generate in.
• For the best performance, go into the dimension you will pregenerate.

Radius:

• The amount in blocks to generate in each direction from the center point.
• If you set this to 400 in total an area of 800 by 800 would be pregenerated.

X and Z Positions:

• The center position where you want to pregenerate from (Eg. if your radius is 200 it will go 200 blocks out in each direction from XYZ values provided).

Example of an area pregenerated with a radius of 500:
