Geolosys Next
by immails
Geolosys Next is a Forge fork of the Geolosys ore generation mod for Minecraft 1.20.1, with extra changes and a Patchouli field manual.
What it does
Geolosys Next replaces the vanilla ore layout with geological systems, so ore types and resources are placed by generation rules rather than scattered at random. Geolosys is the mod this fork is based on, and the author describes Geolosys Next as an attempt to port Geolosys 1.20.1 with changes of its own. The author also notes that parts of it are broken and that testing is welcome.
The ore generation is configurable through datapacks, and the mod comes with a set of predefined default resources that work without changes. It is meant to integrate with tech mods, and the author says it works with a large majority of them. Patchouli is required, and its in-game field manual teaches players the generation types and resources they need to know about, while the wiki covers the rest for mod developers.
Geolosys Next runs on client and server, so both the server and every player need it. Files are published for Forge only, for six game versions 1.20.1 – 1.20.6, with 8.0.5 for 1.20.1 as the latest file. It is open source under the GNU General Public License v3.0 only, and its source code, issue tracker and wiki are public.
