About this Mod

Distant Horizons SeedGen

A faster, more performant alternative to Distant Horizons native Distant Generator

This is an Addon for DH, so it requires it and doesnt replace it

Showcase Video

Statistics

These were optained from various tests under the same conditions on the same hardware

  • For DH versions before 3.3 (Pre N sized Worldgen) Seedgen provides various speedups, from 10.7x in the Overworld to 2.3x in the Nether

  • For DH versions past 3.3 (N sized Worldgen) Seedgen can provide full detail at huge render distances while still being 5.6x faster than DH Hyperspeed (speedup increases further with render distance)

NOTE: SeedGen is NOT outdated when using the new DH Hyperspeed Generator! It provides faster speed, features such as trees directly, and better mod compat!

Capabilites

  • SeedGen calcualtes terrain directly from the seed instead of fully generating it, realistically faking assets such as trees, and placing structures at the correct coords differently.
  • Works slower in multiplayer, due to native DH and network restrictions
  • Once an area is explored, Distant Horizons will save the terrain as normal
  • SeedGen is now officially COMPATIBLE with EVERY SINGLE* NOISE BASED TERRAIN GENERATION MOD
  • However, many different mods use many different mechanisms of altering terrain. Some are readable (Tectonic, Lithosphere, Terralith, JJThunder, Continents and MANY more infact) and some use custom generators or mixins (Big Globe, Farlands) and are therefore incompatible by design. This is, by SeedGens design, NOT fixable (in most cases).
  • SeedGen 0.7.0+ is compatible with custom structure mods
  • SeedGen 0.8.0+ has lightning fast server generation
    • For this, DH and SeedGen must installed on both client and server, and mods and datapacks the server uses to edit generation need to be installed client side.
    • If any conditions are not met, SeedGen informs the user of which and stands down.
    • Install server-side mods to your client, put server-side datapacks in your native "seedgen-datapacks" folder
  • SeedGen is not on some devices (it is not known why, some work, some dont) compatible with mods such as C2ME, noisium or fast noise, as they change how minecraft handles what this mod uses to generate its LODs

  • The two images provided were taken with exactly the same angle, different worlds, on the same seed and after the same amount of time, showing how much faster SeedGen is that normal DH Generation

Frequently Asked Questions

Distant Horizons SeedGen server crashes on startup – what to do?

Distant Horizons SeedGen officially supports fabric, forge, neoforge for Minecraft 26.3, 26.2, 26.1.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Distant Horizons SeedGen – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Distant Horizons SeedGen consumes the most tick time.
