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.

UECortexDemo: (Upload phase)

A UE-cortex output sample project (downloadable [Link will be available soon])

Generated by UE-cortex from a single prompt:

    "Third-person action RPG. Player has health and stamina attributes through GAS. Three enemy types with behaviour-tree AI that flanks. Inventory with equippable weapons. Save/load. HUD showing both bars."

UE-cortex expanded that into a Game Design Document, resolved a dependency-ordered task graph, and dispatched the work to specialist agents (C++/GAS, multiplayer, AI).

Also included: PLACEHOLDERS.md, every asset still requiring a human — and

ACTION_RPG_INTEGRATION.md, mapping each generated class back to the agent that produced it.

This is a scaffolding sample, not a complete game.

The C++ compiles clean against UE 5.7.

Behavior Trees, meshes, item data, materials is deliberately left undone and documented as such.

Download it to see the structure the tool actually emits.

The project is under constant development. Expect updates for the plugin continuously.
