FractalTerrain
by batata1_ojg
FractalTerrain is a Fabric world generation mod for Minecraft 1.20.1 that reshapes terrain with a deep learning model trained on landscape data.
What it does
Terrain is generated by a deep learning model rather than the standard noise routines. The model was trained on digital elevation models of real landscapes captured from satellite data and other sources, so the generated ground takes on shapes modeled on natural relief. The mod also reworks biome placement and sets up realistic temperature zones, with tectonic placement and rock strata adding variety to the underground layers.
The mod comes in two scales. The large generator produces terrain up to 1800 blocks in height, and the small version is a scaled-down generator that reaches 400 blocks. Rivers meander across the surface, and the mod works alongside biome mods. Installation needs Fabric API. The author recommends running the mod with Java 21, even though the game version itself runs on Java 17, which the author also lists as a good option for installing the game.
Key features
Learned terrain shapes
A deep learning model generates the ground, trained on digital elevation models of real landscapes.
Large and small generators
The large generator reaches 1800 blocks in height and the small version reaches 400 blocks.
Rivers and temperature zones
Winding rivers cross the terrain, and temperature zones with tectonic placement set where biomes form.
Rock strata
Layered rock strata appear in the generated terrain, giving the underground more visible structure.

Use cases
Who it’s for: Players who want larger and more varied landscapes in a new or existing 1.20.1 world, and server owners who want generated terrain with real-world relief. Biome mods can be used alongside it.
How it compares
Fractal World is an open source Fabric mod under the MIT License, published for 1.20.1 – 1.21.4 and running on the server alone, so players join without installing it. ZonedClimate is also open source, under CC0 1.0 Universal, but targets 26.2 only and needs the server while the client may skip it. Fractal Forests is open source under the MIT License, works on client and server, and covers 1.21.8 – 1.21.10 rather than 1.20.1.
