StructureOverlapless

About this project

What does StructureOverlapless add?

Overlapless

A simple mod that prevents structure and feature overlap during world generation.

Works server-side (client installation optional).

How It Works

When a structure is about to be generated, the mod checks for existing structures in its bounding box. If overlap is detected, generation is skipped to prevent conflicts.

Features (v1.1.0+)

  • UnskippableStructures: Configure structures that always generate, even when overlapping (in overlapless-common.toml)
  • SkippableFeatures: Prevent specific configured features from overlapping with structures
  • Logging Options: Toggle structure/feature skip event logging

Version Support

  • 1.20.1+: Full support with latest features (v1.1.0)
  • 1.16.5 & 1.18.2: Limited support (v1.0.6 only) - these versions are semi-abandoned and may not receive v1.1.0 updates

Important Notes

⚠️ Reduced Structure Density: This mod prevents overlapping by skipping generation, not relocating structures. You may find fewer total structures in your world.

⚠️ New Chunks Only: Only affects newly generated chunks. Already generated terrain remains unchanged.
