Ever loaded into a new Minecraft world only to find a village awkwardly clipping through a desert temple? Structure Overlapless Mod tackles that exact frustration by preventing structures from generating on top of each other during worldgen. Rather than trying to relocate conflicting buildings, it uses a simple first-come-first-served approach — the first structure claims the space, and any later conflicts are quietly skipped. The result is noticeably cleaner terrain, though you may encounter slightly fewer structures overall.
Key Features
- Overlap prevention system — Structures no longer clip into or stack on top of each other during world generation, eliminating those jarring visual glitches in newly created worlds.
- First-come-first-served priority — When two structures compete for the same space, whichever generates first claims the area. Conflicting structures are skipped entirely rather than awkwardly relocated nearby.
- Configurable UnskippableStructures list — Mark specific structures (like strongholds or monuments) as unskippable so they always generate, even if they overlap with something else.
- Configurable SkippableFeatures list — Fine-tune which world features (beyond structures) should also respect overlap rules, giving you granular control over worldgen behavior.
- Built-in logging — Enable logging to track exactly which structures and features were skipped during generation, useful for debugging or tweaking your configuration.

FAQ
Does Structure Overlapless Mod work on existing worlds?
No — the mod only affects new chunk generation. Already-generated terrain and structures in your existing world will remain unchanged. You need to explore new chunks or create a new world to see the overlap prevention in action.
Will this mod reduce the number of structures in my world?
Yes, slightly. Because conflicting structures are skipped rather than moved elsewhere, you may encounter fewer total structures. However, you can use the UnskippableStructures config to ensure important structures like strongholds always generate.
Is Structure Overlapless Mod compatible with mods that add new structures?
The mod works at the worldgen level, so it applies to any structure that goes through Minecraft's standard generation pipeline. Modded structures that use the vanilla structure system should be handled the same way as default ones.
