Blueprint AI

AI-powered editing for Unreal Engine

Blueprint AI is an Unreal Engine editor plugin that connects AI coding agents directly to the UE editor. It exposes a rich set of tools that let AI agents read, create, and modify Blueprints, materials, Niagara systems, animations, level sequences, and more — all from a chat interface inside the editor.

Key Features

  • Multi-agent support — Connect to Claude Code, Gemini CLI, Codex, OpenCode, Cursor Agent, Copilot CLI, or a built-in OpenRouter agent. Switch between them per session.
  • 25+ editor tools — From Blueprint editing and graph wiring to Niagara VFX, IK rigs, physics assets, animation montages, and Python scripting. The AI operates on real engine APIs.
  • MCP server — An embedded HTTP server implements the Model Context Protocol, letting any MCP-compatible client call the same tools without going through a chat agent.
  • Context attachments — Right-click a Blueprint node or asset in the Content Browser to attach it as context for your next prompt. Paste images from the clipboard for vision-capable models.
  • Session persistence — Multi-tab chat sessions with full history saved to disk. Resume conversations across editor restarts.
  • AI content generation — Generate images via OpenRouter vision models and 3D models via the Meshy API, then import them as Texture2D or StaticMesh assets automatically.
  • Agent profiles — Create named profiles that restrict which tools are exposed and append custom instructions per domain (animation, level design, etc.).
  • Usage tracking — View token counts, cost breakdowns, and rate-limit status per session.

Supported Platforms

  • Unreal Engine 5.5 and 5.6
  • Windows and macOS
  • Editor-only (not included in packaged builds)
