TellusCN

Worlds generated with TellusCN follow real geographic data, so mountains, coastlines and climate zones take their shape from elevation and land cover information rather than vanilla noise. The generation scale, height limits and other terrain settings can be adjusted, and a built-in preview screen shows the chosen settings before a world is created. Players can also enable optional weather and time systems that are loosely driven by real-time conditions.

The fork is a Chinese community adaptation of the Tellus mod, with a Chinese mirror CDN so terrain data loads faster for players in China. It requires an active internet connection because terrain, land cover, climate and weather data are fetched as the player explores, so data use grows with the area travelled; the mod does not work offline. Survival features are still incomplete, including some structures and biomes, and future updates may break existing worlds, so the mod suits testing and exploration more than long-term survival.

When Distant Horizons is installed, TellusCN supplies its own world-generation override, so distant terrain is produced from the mod's geographic data and settings. The mod is open source under the GNU Lesser General Public License v3.0 only, and it is published for Fabric across three release versions, 1.20.1, 1.21.1 and 26.1.2.
