Seedgen

A client-side Fabric mod that locally generates vanilla terrain from a known world seed without asking the server to load or generate every source chunk.

Supported mods: Voxy, Xaero's World Map, JourneyMap.

[!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.
