THE WORKSHOP
Lay out a ruined keep, a winding cavern or a wildflower clearing. Work at tabletop scale with a library of original scenery.
Place floors, walls, doors, trees and props. Snap pieces together, move them by dragging, and adjust their elevation. Wide curves and 45° wall sections give your rooms space to breathe.
Save editable projects to your computer. Open them offline and keep building. Recovery files help protect work in progress. Updates do not replace your personal projects.
The small launcher downloads the editor and scenery from GitHub. It checks for signed updates when online and reuses unchanged packs. The installed editor works without an internet connection.

BEYOND THE DUNGEON
Meadows, flowers, shrubs and trees. Rivers and bridges. Weathered cave walls and broad stone curves. Original scenery, with sculpted detail that becomes part of the print.
Preview colours and fine material shading are not included in STL files.
FROM SCENE TO TABLE
Export an STL print pack with separate terrain pieces, a quantity list and your editable project. Open the STLs in Bambu Studio, choose your printer and material, then inspect supports and sliced layers.
The open-source release uses Foundry Link, our original openly licensed connector. Print a small connector fit test before a full scene. It is a new system, with no claim of compatibility with existing OpenLOCK prints.
