How does Pregen actually work?
so i want to pregen 1000 Chunks but when i leave the server the CPU usage drops from 90% to 5-10% and i doubt that its actually effectively pregenerating chunks.. when i am ingame it is sending me chunks and potentially generating them at the same time.. is this a bug or am i doing something wrong?

pregenning normally only works when someone is online yes, because there needs to be someone to request chunks from the server

but you can also use the /dh pregen command to start a pregen without players online
ok i stopped and restarted the pregen and now it works even when i am not on it. but while pregenning will it also send those pregenerated chunks back to my client or will that happen after the pregen? as i still saw new chunks appearing on my end

if youre on the server, itll also send these generated LODs to you yes
if youre not on the server, itll send these once you join
aight thanks for clarifying! 🙂
