FabricForgeNeoForgeClient and serverMIT LicenseOpen source26.1.2

What it does

The mod brings the world size and biome scale options of the Legacy Console Edition into Java Edition. Numerous settings can be changed, and the mod's common options are accessible per world, so one server can host worlds built with different sizes and scales side by side. It requires Factory API on Fabric, Forge and NeoForge.

The server and every player need the mod installed. Files are published for Fabric, Forge and NeoForge, all for 26.1.2, with 0.0.1 as the latest build on each loader. The source code is open source under the MIT License, and the issue tracker is public. Support for Legacy4J, vanilla and other Legacy-themed mods is listed by the author.

Key features

  1. Legacy console world sizes

  2. Biome scale settings

  3. Per-world options

    Most of the mod's common options can be set for each world rather than globally.

  4. Customizable generation
