FMG-to-MC
by v-cigales
FMG-to-MC turns maps exported from Azgaar's Fantasy Map Generator into explorable Minecraft worlds, and it is built for Fabric on version 1.20.1.
What it does
Azgaar's Fantasy Map Generator exports a set of GeoJSON files describing cells and rivers. FMG-to-MC reads those files and shapes a world's terrain after the map, so the landforms and water courses in the world follow the geography drawn in the generator. A player creates a new world, picks the FMG Fantasy Map world type and the mod generates the terrain from the exported files.
The default scale places roughly 125 meters of the map into one block horizontally, while the vertical scale compresses height far less. Trees, vegetation, ores and mobs are not mapped from the map; the mod only shapes terrain and water, and the rest comes from vanilla biome generation. Only rivers that Azgaar generates natively are supported, and rivers drawn by hand do not generate correctly.
The server requires the mod, and clients may install it as well. The code is released under the GNU Lesser General Public License v3.0 only and is open source. Files exist only for Fabric, for 1.20.1, with 0.1.0-alpha as the latest file, published on 2026-06-14.
Key features
Map-based terrain
Terrain shape and biomes come from the exported map, so a generated world reflects the layout of the source map.
GeoJSON import
Cells and rivers are read from two exported GeoJSON files placed in a folder inside the Minecraft directory.
World type selection
A world created with the FMG Fantasy Map world type uses the imported map when the world is generated.
Native rivers only
Only rivers generated natively by Azgaar are supported, so hand-drawn rivers are not placed in the world.
