# unreal-engine
Operate a live Unreal Editor over MCP through Unreal Engine 5.8's native in-editor MCP server: spawn actors, build and compile Blueprints, compose levels, configure lighting, inspect Slate widgets, and run automation tests. Connects to the editor's local HTTP endpoint, no third-party server to install. The bundled skills lean into list-first, compile-then-spawn discipline because editor writes silently no-op more than any other DCC.

## What unreal-engine does, in the publisher's words

Unreal Engine 5.8 ships a native MCP server inside the editor. Artyx connects to it directly over local HTTP, there is no third-party server to install.

Install instructions: Unreal MCP in the Unreal Editor

That URL is interface.docsUrl in plugin.json, and it is what the desktop's "How to install" button opens. Epic owns the enable-the-plugin and start-the-server procedure; it is not mirrored here or in the manifest.

## Skills

- unreal-animation-rigging: Build and debug Unreal Engine 5.6+ character animation. Use for skeleton import, retargeting, Animation Blueprints, state machines, montages, root motion, IK Rig, Control Rig, animation notifies, or runtime animation performance.
- unreal-assets-materials: Create, import, validate, and optimize Unreal Engine 5.6+ assets and materials. Use for FBX or glTF ingestion, texture settings, PBR material graphs, Material Instances, Nanite, virtual textures, asset references, or content quality checks.
- unreal-blueprints-cpp: Build Unreal Engine 5.6+ gameplay with Blueprints and C++. Use for actors, components, input, communication, collision, movement, gameplay events, network replication, debugging, or choosing a native implementation boundary.
- unreal-cinematics: Create Unreal Engine 5.6+ cinematics and final renders. Use for Level Sequences, Sequencer tracks, Cine Camera, Control Rig animation, camera cuts, shot organization, Movie Render Queue, Movie Render Graph, or render-quality validation.
- unreal-engine-mcp: Operate a connected Unreal Editor safely through Epic's experimental native Unreal MCP server in UE 5.8. Use for tool discovery, actor and asset edits, material-instance work, editor inspection, or automation through the live MCP surface.
- unreal-lighting-rendering: Light, render, and diagnose an Unreal Engine 5.6+ scene. Use for Lumen, light mobility, exposure, post process, reflections, shadows, Nanite interactions, GPU debugging, renderer selection, or frame-quality tradeoffs.
- unreal-overview: Route Unreal Engine 5.6+ work to the right Artyx skill. Use for choosing a production workflow across C++, Blueprints, rendering, animation, worlds, cinematics, performance, packaging, or the experimental UE 5.8 native MCP server.
- unreal-performance-packaging: Measure, optimize, test, cook, package, and ship Unreal Engine 5.6+ projects. Use for Unreal Insights, CPU/GPU/memory bottlenecks, automation tests, configuration, cooking, packaging, staging, target-platform verification, or release regressions.
- unreal-project-architecture: Design or refactor a maintainable Unreal Engine 5.6+ project. Use for Gameplay Framework choices, C++ versus Blueprint boundaries, modules, plugins, Data Assets, asset ownership, input, or scalable project structure.
- unreal-world-building: Build scalable Unreal Engine 5.6+ levels and open worlds. Use for level assembly, actor placement, World Partition, Data Layers, One File Per Actor, HLOD, Landscape, foliage, PCG, streaming, or environment validation.
