Jaki Versatile Structures
by Jackiefr
Jaki Versatile Structures adds 31 small and medium vanilla-style structures to a world, filled with loot and some custom enemies.
What it does
The structures are built in the vanilla style and stocked with loot. Many of them use custom player heads to add detail, and some of the mobs found inside increase the variety of encounters during adventures. The content list includes new structures, archeology searches and updates to existing structures, and the mod is grouped under World generation with Adventure as a secondary category.
Installation works on Fabric, Forge and NeoForge. Files exist for two game versions, 1.20.1 and 1.21.1, with 0.2.0 for 1.21.1 as the latest Fabric and NeoForge file and 0.1.4 for 1.20.1 as the latest Forge file. A server running it needs every connecting player to have it too. The code is open source under the GNU General Public License v3.0 or later, and the source code is public.
The mod was first published on 2026-01-23 and last updated on 2026-06-05. The author notes that nothing further is planned at present, and the Ancient Structures mod by a different author is listed as a related project.
