How do I start pre-generating chunks?
Run the mod's pre-generation command from chat or the server console, specifying the center point and radius you want covered. The mod then generates chunks in the background while you keep playing, so you don't need to stand around waiting.
Does pre-generating work on my existing world?
Yes, you can pre-generate chunks for a world you've already been playing in. The mod only generates chunks that don't exist yet, so already-explored areas are left untouched.
How do I stop pre-generation once it's running?
Use the mod's stop or cancel command to halt an in-progress pre-generation task. Progress made up to that point is kept, so you can resume later without starting over.
Can I keep playing while chunks generate?
Yes, pre-generation runs in the background and you can continue playing normally. Expect some extra lag or reduced tick rate while it works, especially on lower-end machines.
Why is my game lagging so much during pre-generation?
Pre-generation is CPU and disk intensive, so some slowdown is normal. Lower the generation speed or throttle the rate in the mod's settings to reduce the impact on your gameplay.
How do I check how much is left to generate?
Use the mod's progress command to see how many chunks have been generated and how many remain. This lets you estimate how much longer the task will take.
What radius should I pre-generate?
Pick a radius that covers the area you actually plan to explore, since larger radii take much longer and use more disk space. A modest radius around your base or spawn is usually enough to smooth out exploration lag.
Will pre-generating break my world or existing builds?
No, pre-generation only creates new chunks and doesn't modify chunks that already exist. Your builds and explored terrain stay exactly as they were.
Does pre-generating work on a server with other players?
Yes, pre-generation can run on a multiplayer server, and all players benefit from the reduced exploration lag afterward. Run it during low-traffic hours if the performance hit affects other players.
How much disk space does pre-generating use?
Pre-generation writes every generated chunk to disk, so the space used grows with the area you cover. Larger radii can add up quickly, so check your free space before starting a big job.
What does the World Pre Generator Mod do?
It pre-generates Minecraft world chunks in advance so there is less lag when players explore. It works per dimension and is run through commands.
Do I need the World Pre Generator Mod on the client?
No, the mod is only needed on the server side, but it can also be used on the client side.
What Minecraft versions does the World Pre Generator Mod support?
The mod file lists Minecraft 1.21.1 through 1.21.10 on NeoForge. The Modrinth project page also lists 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2 and 26.3.
Which mod loaders does the World Pre Generator Mod support?
The mod file lists NeoForge, and the Modrinth project page lists both Forge and NeoForge.
How do I see which pre-generation tasks are running?
Use /pregen list to list all running pre-generation tasks.
How do I cancel a pre-generation task?
Use /pregen cancel to cancel the task for one dimension, or /pregen clear to cancel all pre-generation tasks.
Does pre-generation continue after a server restart?
Yes, pre-generations are continued after restarts.
What do the pre-generation progress messages mean?
They show the dimension, chunks generated, total chunks to generate, percentage finished, and the chunk generation rate per second. Progress is computed in chunks.
How do I turn pre-generation progress feedback on or off?
Use /pregen sendFeedback to see whether progression feedback is enabled, and /pregen sendFeedback to enable or disable it. Generation start and finish feedback are not affected.
