Voxygen

A client-side Fabric mod that generates vanilla terrain locally and submits it to Voxy. It fills distant Voxy terrain without asking the server to load or generate every source chunk.

[!IMPORTANT] Multiplayer generation requires the exact world seed. A wrong seed produces terrain that does not match the server. Due to MC-55596, generated features such as trees may be inconsistent with the server even when the seed is correct.

Commands

Command Description
/voxygen on Enable Voxygen.
/voxygen off Disable Voxygen and stop the active session.
/voxygen toggle Toggle Voxygen.
/voxygen status Show the world, seed, radius, progress, thread usage, and result counters.
/voxygen radius Show the configured radius in vanilla chunks.
/voxygen radius <radius> Set the radius. Default: 64; minimum: 1.
/voxygen threads Show the worker-thread count.
/voxygen threads <threads> Set worker threads from 1 to 256. Default: 32.
/voxygen progress Show whether the progress boss bar is enabled.

/voxygen seed Show the effective seed for the current world.

Performance notes

  • Chunk generation is CPU- and memory-intensive. Increase threads gradually rather than immediately using every available logical processor.
  • A larger radius increases the number of large regions quadratically.

Supported Versions
