Voxy WorldGen
by iseeethan
With Voxy WorldGen installed, chunks ahead of a player are generated in the background and passed into Voxy automatically, so distant terrain is ready sooner.
What it does
The mod works as a passive chunk generator. It produces chunks in the background while the player plays, then feeds them into Voxy for level-of-detail rendering. Generation speed and the size of the work queue can be set in the config, so server owners can trade throughput against load.
Voxy WorldGen is a rewrite of the author's earlier Voxy World Gen mod and is a separate project, with its own code rather than a copy of another generator. It depends on Better ModList, Cloth Config API and voxy, with Mod Menu as an optional addition. Fabric files cover 1.21.1 – 26.2 and NeoForge files cover 1.21.1; the license is custom and the project is not open source.
Key features
Background chunk generation
Chunks are generated in the background at a configurable pace, without pausing normal play.
Automatic Voxy ingestion
Generated chunks are handed to Voxy automatically, so the distant view fills in without manual steps.
Adjustable queue size
The number of chunks waiting to be generated can be changed to match the power of the machine.
Server-side generation
Generation can run on a server, so players connected to it receive the prepared chunks.

Voxy Auto LOD is a NeoForge mod for 1.21.1 only, under the MIT License, where either side can run it and neither needs it, and it is not open source. Voxy WorldGen is a separate custom-licensed project for 1.21.1 – 26.2 that generates chunks rather than handling level-of-detail rendering.

What the author says
This is a rewrite of my old Voxy World Gen mod, this mod is NOT a fork of the passive chunk generator mod and instead is a entirely different mod. I've been using BisectHosting for a couple months now and they've always been reliable and actually really easy to use! I have partnered with them to become a partner now!…
