Modular Building System

Modular Building System is a modular building plugin for Unreal Engine. Its core systems are implemented in C++, with interfaces available for Blueprint use and extension.

The plugin is built around building entities, Chunk management, and HISM batch rendering, supporting both static building modules and independent Actor-based buildings within the same project.

Key Features

• HISM and Actor rendering modes
• Chunk-based building management
• Building preview, placement, movement, and removal
• Socket snapping and grouping rules
• Server-authoritative validation for multiplayer games
• Incremental replication of building entities
• Structural support and collapse detection
• Extensible building cost and effect systems
• Standard workflows for Blueprint-only projects
