SeedMapper 2.0.0 is out of beta! After almost three years since 1.18 released, SeedMapper is fully up to date again! SeedMapper now has full biome and structure support for all Minecraft versions since 1.0. Under the hood, SeedMapper now uses cubiomes by Cubitect, a blazingly fast C library that mimics Minecraft's biome and feature generation.
Important note: You must have Java 23 installed to use this mod. See here for more information.
Download available on Modrinth.
This release is for Minecraft 1.21.2 and above, for 1.21.1 the nearly identical version 2.0.0-beta.4+1.21 can be used.
