STRUTTURA
by Struttura
Players who want to share builds across worlds can use Struttura, a Fabric mod that stores buildings in a cloud catalog and places them into survival worlds.
What it does
Struttura lets players select an area, save the buildings inside it with their metadata and rooms, and publish them to a community cloud. From the game, a player can browse and search the shared catalog, pull a building into another world, and manage a personal library without leaving the game. Buildings can also appear while exploring new chunks, turning survival travel into a source of discovery.
Creations can include mobs, entities and command blocks, so builders can design full adventures, traps and interactive experiences. Randomized rooms inside a building can produce a different layout each time it spawns. Struttura is client and server, so the server and every player need the mod. It requires Fabric API and is published for 1.21.11 only, in two variants included in one package, under the GNU General Public License v3.0 only. The source code is open source and the issue tracker is public.
