3D Dungeon Generator

What 3D Dungeon Generator is

3D Dungeon Generator creates procedural room-and-corridor dungeons in a browser, with layouts designed to be solvable. Users can adjust room count, room size, corridor width, and map dimensions, while the tool places non-overlapping rooms and carves connecting corridors. A seed and the same settings reproduce a layout, with entrance-to-exit routes and optional extra corridor links. Its real-time 3D preview offers orbit, top view, fit controls, and first-person walking from the entrance. Themes include Stone, Backrooms, Dungeon, Concrete, Sci-Fi, and Hedge; users can also add custom wall, floor, and ceiling textures. GLB export includes geometry and current materials, with optional ceiling and solution path. Custom texture support in exported GLB depends on browser image decoding. The Free Creator Tool costs nothing and supports dungeon sizes from 16×16 presets to 60×60 custom dimensions. LevelRift Labs says no signup or subscription is needed, and original texture files are not uploaded by the app.

Who it suits

It suits people prototyping game levels, taking part in indie game jams, or developing dungeon, crypt, bunker, and level concepts. Its GLB export supports Blender and other GLB-compatible workflows.

Limits

The Free Creator Tool covers dungeon sizes from 16×16 presets to custom dimensions up to 60×60. Custom texture support in GLB export depends on browser image decoding.

Getting started

1. Open the 3D Dungeon Generator website in a browser.
2. Choose map dimensions and adjust room count, room size, and corridor width.
3. Set a seed if you want to recreate the layout later with the same settings.
4. Select a theme or provide custom wall, floor, or ceiling textures.
5. Use the preview controls to inspect or walk through the map.
6. Export the dungeon as GLB, with an optional ceiling or solution path.

Verdict

3D Dungeon Generator offers adjustable procedural layouts, a live 3D preview, and GLB export without signup or subscription. Keep the browser-dependent custom texture limitation in mind when exporting.
