WorldWeaver Remastered (WoVer)

The essential foundation for breathtaking new worlds.

WorldWeaver Remastered (or WoVer for short) is a powerful, modern Fabric utility mod and API that completely streamlines complex world generation and modding tasks. Built as the direct modern successor to BCLib, WorldWeaver provides the core infrastructure that makes massive and complex mods like BetterEnd Remastered and BetterNether Remastered possible.

By fully embracing Minecraft's data-driven world generation methodology, WorldWeaver gives modpack developers and creators unprecedented flexibility to modify and create completely custom dimensions, biomes, and terrain flawlessly.

🌟 Key Features

  • Advanced World Generation API: The ultimate framework for creating lush new biomes, complex terrain shapes, and custom surface rules seamlessly. It does the heavy lifting so world-gen mods can focus on content.
  • Data-Driven Architecture: Embrace the power of modern Minecraft! WorldWeaver heavily leans into ResourcePacks and DataPacks, giving you unparalleled control to tweak biomes, spawn rates, and generation parameters without needing to touch a single line of code.
  • Seamless Mod Integration: Designed from the ground up to play nicely with the vanilla game, complex datapacks, and other massive world-generation mods in the Fabric ecosystem.
  • Essential Library: A mandatory dependency to run the breathtaking BetterEnd Remastered and BetterNether Remastered experiences, packing shared utilities, math helpers, and rendering expansions into one performant package.

Why "Remastered"? (Exclusive to this Version)

This project is a deeply optimized, modernized continuation of the original WorldWeaver mod, specifically tailored, stable, and hardened for Fabric 1.21.1.

We didn't just port the library; we fixed critical fundamental issues to ensure the smoothest, most stable experience possible for modern modpacks:

  • Performance & Core Fixes: Overhauled unstable generation logic and thread-safety issues from older versions. Say goodbye to dimension-loading freezes, deadlocks, and generation lag spikes!
  • Sodium & Optimization Compatibility: Fixed critical injection boundaries in the core rendering and terrain hooks. No more sudden crashes when paired with modern optimization mods like Sodium!
  • Polished Codebase: We've squashed console warnings, modernized the API surface, and provided a seamlessly clean log for modpack creators.
