World Seed

This page has interesting world seeds for players looking for specific biomes near spawn. "Realistic Alpha" is the default world gen for GT New Horizons worlds, and the only one recommended to be used. If the wrong world generation has been used for a world, see Changing World Gen for steps to correct the issue.

Due to GTNH's unique world generation, some world features do not correctly generate identically every time for the same seed. In general this makes for very minor changes between iterations of the same seed. Some features which are generally stable, such as ore gravel, may be overwritten by another non-deterministic feature. Seed maps and descriptions should be taken as a general guide rather than an absolute promise.

• Applied Energistics 2 Meteors

WIP! This page is a Work In Progress. You can help out by adding more information to the page.
