Hex Atelier — Medieval World Painter

Pick a model. Paint a world.

Hex Atelier is a free browser preview and map painter for Medieval Hex Worlds by ChillLands. Explore 388 low poly model families and ten cultures in a shared hex system.

Build with measured connections

Draw roads with a continuous brush stroke. Place buildings on vacant flat hexes, connect walls and gates with measured sockets, and create suitable support for large scenery, boats and coastal structures. It opens on the Old World Map: Europe, Africa and Asia in 8,009 hexes, with the ten kingdoms at their real places. You can also start from any of the ten cultural villages or open a blank canvas.

Save your layout

Save and open map JSON files, export a 3D GLB layout or capture a PNG photograph. The Expanded Collection includes native Unity prefabs and a JSON importer that recreates your layout. The editor also saves your current map in this browser.

Controls: left click to paint, right drag to orbit, middle drag to pan and wheel to zoom. B / E / I select brush, erase and pick; R rotates 60°; Ctrl Z / Ctrl Y undo and redo. Use the fullscreen button for a larger workspace.
