What's new

NoStructureOverlap 3.0.1 — Minecraft 1.20.1 (Forge 47.4.20)

Highlights

  • New overlap engine: blocks overlapping different structure registry IDs using vanilla StructureStart bounding boxes (after piece / jigsaw layout, before blocks place)
  • Same structure ID may still overlap; pieces inside one start are never treated as conflicts
  • Server-authoritative — clients do not need the mod

Changes from 2.x

  • Replaced estimated radius / placement heuristics with MiniHUD-style AABB checks
  • Removed legacy placement validator and MiniHUD-related command clutter
  • Config focused on enable / 3D vs XZ / whitelist / blacklist / per-structure overrides
  • Status commands are read-only (status, info, structures)

1.20.1 packaging

  • Built for Forge 47.4.20 (Java 17)
  • Jar name: nostructureoverlap-1.20.1-3.0.1.jar
  • Mixin refmap + pack.mcmeta included for production Forge loads
