Plugin showcase: UE-cortex showcase

UE-cortex is a multi-agent orchestration system that takes a natural-language game description and distributes the work across 11 specialist AI agents — each with deep, domain-specific Unreal Engine 5 knowledge.

The result is a structured, phase-built UE5 project covering systems, multiplayer, world, blueprints, build pipeline, UI, audio, cinematics, performance, technical art, and AI.

Each agent reads only the knowledge it needs for the current task (from domain-scoped ref files), executes editor actions via an MCP server connected to the live UE5 editor, and writes its outputs to a shared contract store (`GAME_STATE.json`). Agents do not call each other — contracts are the only inter-agent surface.

Requirements

- Python 3.11+

- Unreal Engine 5.x (editor running, optional for stub-mode orchestration)

- An engine-interface MCP server running locally (optional)

- LLM API key or a local model server (Ollama / LM Studio)

- Claude Code, Cursor, or Windsurf as the AI IDE

Note: This tool is compatible with Unreal Engine 5.

Note: This plugin requires the "PythonScriptPlugin" enabled.
