Immersive Structures II: Nether edition
Immersive Structures II: Nether edition adds generated structures to the Nether dimension, and the server must run it for the structures to appear in new chunks.
What it does
The mod places additional structure packs in the Nether. Structures spawn only in chunks generated after the mod is installed, so an existing world gains them as players explore new areas. Updating to a newer release and adding the mod to an existing world are both described by the author as safe, with the note that older chunks stay unchanged.
Installation needs a server running Fabric, Forge or Quilt, and the mod is published as a single universal build for all three loaders. It is required on the server and optional for players. Files are available for game versions 1.19, 1.19.1, 1.19.2, 1.19.3, 1.19.4 and 1.20, and the latest file for each loader is 1.1.0 for 1.20, published 2023-06-11. The mod is also distributed as a data pack, and it is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, so it is not open source. Source code and an issue tracker are publicly linked.
Key features
Nether structure packs
Adds structure packs to the Nether, extending the dimension with generated buildings in new chunks.
No vanilla changes
Existing vanilla structures are left as they are, so the mod only adds to the Nether terrain.
Structures in new chunks
Structures generate as chunks are created, so areas explored for the first time show the new buildings.

Use cases
Adding Nether content to a server
Server owners add the mod to a modded or vanilla-based server to give the Nether more places to explore.
Modpack building
Modpack makers can include the mod with credit and a link to the author's page, as the author allows.
Who it’s for: Server owners and modpack authors who want more generated structures in the Nether. Players need nothing installed on their side.
How it compares
Simple Structures: Caves and Simple Structures: Desert are both under the MIT License and not open source; Caves covers 1.19.2 – 26.3 and Desert covers 1.20 – 26.3, both with Fabric, Forge, NeoForge and Quilt builds, and both work on either side, and neither needs it. Towns and Towers is published under the Creative Commons Attribution Non Commercial Share Alike 4.0 license for 1.18.2 – 26.3, and it adds villages and towers instead of Nether structures.
