GEODEI Coming soon
Terraforming for Minecraft

Terraforming
Evolved

GeoDei is a desktop terraforming studio for Minecraft. Sculpt terrain in a 3D viewport, simulate erosion, carve rivers, and export a world you can walk into.

Windows 10 / 11 In development
What is this

You design terrain on your computer.
GeoDei builds it as a Minecraft world.

How it works · six steps
01Sculpt
Freshly sculpted voxel terrain: green terraced hills rising to a jagged mountain ridge.
Shape it in 3D Raise ranges and cut valleys from any angle in a native Direct3D 11 viewport.
02Simulate
The same terrain after an erosion bake: ridgelines sharpened and drainage valleys cut into the slopes.
Weather it with erosion Hydraulic, thermal, and fluvial erosion run as brushes you paint, or apply them to the whole map.
03Carve
The same terrain with a winding river carved down the valley floor and cave mouths opened in the hillsides.
Rivers and caves Lay a river down as a spline and the terrain carves around it. Author branching cave systems from presets.
04Paint
The same terrain painted with materials: rocky snow-capped peaks over green valley floors.
Biomes and themes Paint biomes and materials by hand, or apply rule-based themes across the whole map.
05Populate
The same terrain populated with pine forests and paths winding along the river.
Trees and structures Place schematics with a 3D gizmo, or scatter vegetation with rules driven by slope and sun exposure.
06Export
The finished valley exported and rendered inside Minecraft: pine forests, the river, and snow-capped peaks.
Open it in Minecraft Export a Minecraft world with version-aware blocks and biomes, ready to open and explore.

In closed testing.

A small group of builders is testing GeoDei ahead of release. At launch it will be a paid tool with a free trial.
