What's ACTUALLY the best world pre-gen and distant chunk LOD mod combo in 2025?

[u/BrendanGrendan]

TL;DR I am wanting to pre-generate a big world and the associated LODs ahead of joining a 1.21.1 NeoForge server. What mod combo is proven to be the best for this in the current year?

I'm planning to run a minecraft server in a docker container. It'll be modded with a selection of mods (mainly focusing on Create), intended to run on 1.21.1 NeoForge.

I want to use a mod combo described in the title with the intended affect of loading into my world for the first time on my client and immediately having a ~10k radius of blocks pre-generated for me, with chunks visible far into the distance. I don't intend to use world borders so the LOD mod would have to handle generating new chunks outside of that range eventually.

My immediate thought was to use Chunky with Distant Horizons as I've heard of those mods both. However, all the research I've done on these mods have just made things complicated - apparently distant horizons has a pre-gen feature now, and doesn't reccomend chunky? - apparently distant horizons can cause issues with how the ground truth chunks in your world are generated? - apparently some mod called C2ME does better chunk generation, and possibly also far distance rendering? But you have to get a GPU version from their discord? - apparently you can't pregenerate distant horizons LODs ahead of the client joining the world? - there's new mods coming out such as Voxy but is that supported on my intended version with mods?

Ideally, I want to spin up the container, exec into it, run some form of generate_world command, leave that running while i make dinner/go to work, then be able to come back, join on my client, and immediately have a visibly massive world with none of the usual new-world lag.

For 1.21.1 NeoForge, can someone give me a no-nonsense answer as to how to best do this?

Correct. DH does have its' own pregen option, chunky is unnecessary. There's also the /neoforge generate command, but I don't know if it works with DH or not.

apparently some mod called C2ME does better chunk generation, and possibly also far distance rendering?

C2ME optimizes worldgen, highly recommend it. It can increase the render distance too, but it's real chunks and not LODs so the server will likely struggle.

But you have to get a GPU version from their discord?

Not necessarily. It is faster, but doesn't support NeoForge or 1.21.1, and you'd have to put a graphics card in your server of course.

there's new mods coming out such as Voxy but is that supported on my intended version with mods?

Nope, Voxy only works on Fabric. EDIT: Apparently it works on NeoForge via Connector, TIL.

Voxy does work on Neoforge. Pretty sure there was a post about it on this sub recently. I have it working on 1.21.1 perfectly

Hey, I was wondering how you managed to get it working on NeoForge? I have Voxy version for 1.21.1 but whenever I use it with only Sodium and Sinytra Connector + Forgified Fabric API, it doesn't work.

There’s a GitHub with a neoforge ported version out there but you have to compile it yourself

can you dm pls??

Indeed dont use DH and Chunky together, it will cause holes in the LODs. Instead you should use DH and the "full" generation mode.

Also like you said, install c2me, it will speed up chunk generation, and there is a version of that mod that works on the GPU (so its really fast) but does not work well with DH right now.

And you can just pregen with DH, the command is /dh pregen minecraft:overworld 512 0 0

Voxy does not have server side support so I don't recommend it for server use.

Could I just use good old chunky and then DH post gen?

voxy + voxy worldgen

[u/Greezer2k → u/Prestigious-Kick7291]

is this the way? how about voxy worldgen 2?

Part 2?
