Technical Details

Modules:
• DungeonArchitectRuntime (Runtime)
• DungeonArchitectEditor (Editor)

Features:
• Build vast levels procedurally with a single click with various tweakable parameter, either at design time or at runtime.
• Manually design the layout of your levels for more artistic control with custom editor tools (Paint Brush Tool, Volumes etc), and have the plugin automatically build the environment around it
• Design the look and feel of your levels using a powerful Graph based Theme Editor. This lets you instruct the plugin on the meshes and actors to populate around the level as it is being built (around walls, floor, doors, stairs etc)
• Theme files are saved as separate data asset so they can be reused between projects or can be swapped with other theme files to completely change the look
• Supports multiple themes on the same map. For e.g. Wood based architecture in one area, stone based in a nearby area. Override the theme on any part of your level using a custom volume actor
• Supports height variations on the level to make them more interesting
• Extensibility: Dungeon Architect provides you with various extension points so you can provide you own blueprint based logic at different level of the dungeon generation process (Selectors, Transformers, Marker Emitters etc)
