Structure Spread Tweaks
Configurable structure spacing for Minecraft 26.1.x Fabric modpacks.
About this Mod
Structure Spread Tweaks
Structure Spread Tweaks is a Fabric mod for Minecraft 26.1.x that lets modpack authors control how often structures generate.
The mod can make vanilla and modded random-spread structures generate farther apart, closer together, or not at all. It is useful for exploration-focused modpacks where structures appear too often, or for packs that need more control over world generation density.
Features
- Global spread factor for vanilla and modded structures
- Separate toggles for vanilla and modded structure sets
- Per-structure-set and per-structure custom overrides
- Optional id-based structure salt replacement to reduce overlap
- In-game configuration through Mod Menu and Cloth Config
- Config changes apply to the next world load or datapack reload
Requirements
- Minecraft 26.1.x
- Fabric Loader 0.19.2 or newer
- Java 25 or newer
- Cloth Config API
- Mod Menu
Notes
Existing chunks are not regenerated. Test changes in new chunks, a new world, or after deleting generated chunks.
