Additional Structures
Additional Structures places more than 200 small and medium-sized structures into the overworld and the End, and it works alongside biome mods added by other projects.
What it does
Generated structures appear in vanilla biomes as well as modded ones, and each structure type has a config option for its spawn values. The mod works with the /locate command, so players can find its structures in the world. A config datapack is included for editing structure values on 1.18 and later.
Magma Core is a required dependency, and it has to be installed next to Additional Structures. Antique Atlas is optional and adds map support. The mod runs on the server only: players join without installing it, while the server owner installs it on the server side. Files are published for Fabric, Forge, NeoForge and Quilt across game versions 1.12 – 1.21.11, and the code is under All rights reserved, so it is not open source.
