Chunksmith

Pre-generate your world -- and see it.

Chunksmith generates chunks ahead of time so players never wait on worldgen. What makes it different

is that the same pass also builds the distant-horizon data for Distant Horizons or voxy. One run,

two results: a world that loads instantly, and a world you can see to the edge of.

Originally derived from Chunky by pop4959; developed

independently since. Everything Chunky did, Chunksmith still does.

Full documentation is on the wiki -- every

setting, every command, and walkthroughs for pregenerating, trimming, and getting multiplayer LOD

working.

What Chunksmith adds

It builds your LOD data while it pregenerates

No second pass. No re-reading region files. No separate LOD pregen afterwards. Install Distant

Horizons or voxy, run a pregen, and the distant terrain is simply there.

It turns itself on. If a renderer is installed, LOD generation is on. There is no config key to

hunt for.

Already pregenerated? Run the same pregen again. Chunksmith builds LODs from the chunks it

already has -- it does not regenerate them, and it skips everything already done. Pregenerate today,

install a renderer next month, lose nothing.

Multiplayer LOD, with no companion mod. Players joining your server download the pregenerated LOD

data and see the whole world at distance without ever having walked it. The same jar is both halves --

server and client. The Paper/Spigot plugin serves it too, so a modded client against a plugin server

works.

LOD without the disk (4.4.0). /cs horizon <radius pregenerates normally inside the radius and,

past it, builds the LOD and throws the chunk away instead of saving it. A world that would have been

hundreds of gigabytes keeps only the area people actually play in, and the distant terrain still shows

-- in single-player and for every player who joins. Chunks a player goes near are always kept. Not

available with Moonrise; on Paper, the fully generated chunks are dropped but some partly generated

ones at the edges are still written.

It keeps generating while people are playing

Most pregenerators make you choose between speed and a playable server. Chunksmith measures what it

adds to tick time rather than steering on absolute tick time -- so a server already running hot for

its own reasons doesn't throttle Chunksmith to nothing for load it didn't cause.
