Sparse Structures

by m

Sparse Structures makes structures across a world spread further apart, and it can change the spacing of structures added by mods and datapacks.

FabricForgeNeoForgeServer-side onlyMIT LicenseOpen source1.19 – 26.3

What it does

Spacing is set per structure in a config file, so a server owner can make each structure rarer or leave it alone. Changes cover structures from vanilla, from other mods and from datapacks. A spread factor of 0 turns a structure off, and very low values slow world generation noticeably. Biome constraints for each structure can be customized, and structure tags are supported in the config.

The mod is aimed at large modpacks with many structure mods, where the number of villages, towers and dungeons can crowd out exploration. Structures become easier to find by walking, not by using /locate. Config changes take effect only after the game restarts, and settings can differ per world.

Sparse Structures is server-side only, so players join without installing it. It is released under the MIT License and is open source. Files exist for Fabric, Forge and NeoForge across 23 release versions, 1.19 – 26.3. Two other catalog mods, Dungeons Arise Sparse Structures compat and its companion, require it.

Key features

  1. Per-structure spacing

    The spread of each individual structure can be changed, including structures from other mods and datapacks.

  2. World-specific configs

    Each world can carry its own spacing settings, so one save can differ from another on the same server.

  3. Dump structure sets

    The /dumpstructuresets command exports every structure set as a text file that matches the config syntax.

  4. Locate distance fix

    Corrects the distance that /locate reports between the player and the nearest structure.

  5. Structure tags

    Tags can be used in the config to select groups of structures at once instead of listing each one.

Who it’s for: Server owners and modpack authors who run many structure mods and want to control how often structures appear.

Questions

Does Sparse Structures need to be installed on the client?

No. Only the server needs it, and players join without installing anything.

Why does the game need a restart after changing the config?

The config is not reloaded while the game runs. The author notes this behavior may change in future versions.

Is it safe to set a structure's spread factor very low?

A very low value, such as 0.01, makes world generation considerably slower, so the author warns against it. A value of 0 disables the structure instead.
