Design the Adventure, Not Just the Floor Plan

Dungeon Generator is a C++ plugin for Unreal Engine 5 that creates replayable, multi-floor 3D dungeons from your own modular meshes.

Choose how the dungeon should play—open exploration, a clear route from start to goal, keys and locked doors, progression toward a boss, or objectives branching from a hub. Then customize its structure, visual themes, room purposes, interiors, and runtime behavior.

Dungeons can be generated in the editor or at runtime. The plugin provides both Blueprint and C++ APIs, allowing generated rooms and routes to drive enemies, rewards, events, doors, maps, and other gameplay systems.

Important — Version 2.0 is not backward-compatible with Version 1.x

Automatic migration, in-place upgrades, and asset conversion from v1.x are not supported. Do not install v2.0 over a working v1.x project. Keep your v1.x project and matching plugin version, and configure v2.0 separately.

v1.x Dungeon Generator assets, parameters, Blueprint integrations, C++ integrations, fixed seeds, and generated layouts must be recreated or adapted manually.

Shape How the Dungeon Plays

Select one of five Progression Policies as the starting point for your level design:

• Free Exploration — Loops, shortcuts, and optional side rooms

• Start to Goal — A readable main route with controlled branches

• Keys and Locks — Keys unlock progression routes that cannot be bypassed

• Boss Route — Encounters and rest areas build toward a boss room

• Hub Quest — An early hub connects to multiple objective-style branches

The generator evaluates multiple layout candidates and selects the result that best matches your chosen design intent. Room counts, sizes, floors, branches, loops, corridor complexity, and other details remain adjustable.

Give Every Area a Purpose

Gameplay Roles describe why a generated room exists:

• Combat

• Treasure

• Puzzle

• Rest

• Boss

• Secret

Use these Roles through Room Sensors, Blueprint, or C++ to connect generated rooms to your own enemies, rewards, puzzles, events, and game rules.

Zones can be selected by dungeon progress and floor. Each Zone or Gameplay Role can override visual and gameplay settings, helping entrances, deeper areas, upper floors, boss rooms, and secret areas feel distinct.

Gameplay Roles provide level-design information; they do not force a specific combat, treasure, or puzzle system.

Workflow

1. Add a Dungeon Generate Actor to your level.

2. Create a Dungeon Generate Parameter Asset.

3. Assign your meshes and generation databases.

4. Choose a Progression Policy.

5. Adjust Structure, Path, Zones, Theme, and Gameplay settings.

6. Preview the result in the editor or generate it during gameplay.

Related settings are organized into clear groups, making it easy to start with the essentials and fine-tune the dungeon later.
