Chunky
The Chunky mod can pre-generate Minecraft worlds up to a specified distance. This can prevent lag due to chunk generation while moving around the world.
However, it does need time to run before starting a game, and can use a fair amount of storage space.
Important!
Section titled “Important!”In recent versions, Yet Another Bingo will reset the world and seed without restarting the server! This can make mods like Chunky (understandably) a little confused.
To properly regenerate chunks before each game, you’ll need to edit its config (config/chunky/config.json) to enable "forceLoadExistingChunks": true.
Configuration
Section titled “Configuration”The default configuration will generate a distance of 8000 blocks in the overworld, and 1000 in the nether.
Pre-generation will begin as soon as the server starts up. Any pre-generation tasks will be cancelled as soon as you start the game, so it will not have any effect on gameplay.
The pre-generation worlds/distance can be changed in the yet-another-minecraft-bingo/chunky.json config. It can also be turned off entirely, if you’d prefer to run the Chunky commands yourself.
{ "enabled": true, "chunkyWorlds": { "minecraft:overworld": 0, "minecraft:the_nether": 1000 }}
