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.
