What's new

Changelog — Version 1.0.0

Added

  • Automatic prefab world generation: Prefabs placed in Mods/prefabworld/ can spawn automatically as new areas of the world generate.
  • Region-based spawning: Prefabs spawn deterministically per region.
  • Biome + zone matching: Each prefab can be restricted to specific zones and/or biome patterns (* supported as match-all).
  • Spawn chance control: chancePerRegion in each prefab’s config controls how often it spawns when a valid region/anchor is found.
  • Automatic config generation: A .config JSON file is generated for prefabs to control spawn rules, chance, loot tables, chests, and enemies.
  • Loot chest injection: Automatically adds loot chests for discovered structures when appropriate, using zone-based loot tables.
  • Enemy injection: Automatically adds zone appropriate enemies for discovered structures.
