3D Dungeon Generator
What it is
3D Dungeon Generator is a free browser-based tool for making procedural 3D dungeons from rooms and corridors. You can adjust room count, room size, corridor width, and map dimensions, with sizes ranging from 16×16 presets to custom 60×60 layouts. The tool places rooms without overlap and connects them with corridors to form solvable routes from entrance to exit. A seed lets you recreate a layout using the same settings, and optional extra corridors can provide additional connections.
The real-time preview offers orbit, top-down, fit, and first-person walking views. Choose among Stone, Backrooms, Dungeon, Concrete, Sci-Fi, and Hedge themes, or use custom wall, floor, and ceiling textures. Export a GLB containing the geometry and current materials, with optional ceiling and solution path; custom texture handling in GLB depends on browser image decoding. LevelRift Labs says original texture files are not uploaded. Its listed uses include level prototyping, game jams, and Blender or other GLB-compatible workflows. No signup or subscription is needed.
For and against
For
- Adjustable room count, size, corridor width, and map dimensions
- Seeds recreate layouts with the same settings
- First-person walk mode and multiple preview controls
- GLB export includes geometry and current materials
- No signup or subscription is needed
Against
- Custom GLB textures depend on browser image decoding
- Uploaded or third-party assets retain their original rights
The verdict
3D Dungeon Generator combines adjustable procedural layouts, preview controls, and GLB export in a browser tool. Its main caveat is that custom textures in exported GLB files depend on browser image decoding.
Who it suits
It suits game makers and hobbyists developing dungeon, crypt, bunker, or other level concepts. It may also suit users who want GLB assets for Blender or compatible workflows.
