Introducing Blueprint Factory — AI Automation for Game Engines

Why We Built This

Game development involves a staggering amount of mechanical work. Setting up Animator controllers, wiring Blueprint graphs, creating materials, scaffolding scripts, configuring input systems -- these are tasks that follow patterns, and patterns are exactly what AI is good at. But existing AI code assistants live outside the engine. You copy a prompt into a browser, get a response, paste it back, and hope it compiles. That cycle is slow and it breaks your flow.

Blueprint Factory eliminates that round-trip. AI lives inside the editor, has access to your project context, and executes changes directly. You describe what you want in natural language, and the plugin creates the script, spawns the object, sets up the state machine, or generates the texture -- right where you are working.

BlueprintForge for Unreal Engine 5

BlueprintForge is a C++ plugin that adds a Slate UI dashboard to the UE5 editor. It exposes 76+ MCP tools for manipulating Blueprint graphs, spawning actors, editing Animation Blueprints, creating materials, and generating creative assets. Under the hood, five modules (BF_Core, BF_BlueprintTools, BF_AnimTools, BF_AIRouter, BF_ConfigUI) handle everything from HTTP server hosting to Blueprint node wiring.

The 26 BlueprintTools let you create nodes, wire pins, set variable defaults, add functions and events, and manipulate macro graphs -- all from chat. The 6 AnimTools build state machines, add transitions with conditions, configure blend spaces, and validate the resulting controller for errors. And the AI Router connects you to 9 providers so you can generate not just code, but textures, 3D models, voice lines, and music without leaving the editor.

Manny for Unity

Manny is Unity's counterpart, built with UI Toolkit and wrapped in an Art Deco aesthetic that pays tribute to the noir stylings of a certain game about the afterlife. Behind the sharp geometric borders and gold-on-black color scheme, Manny packs the same 76+ tool architecture: Roslyn-powered C# generation, Mecanim Animator automation, scene and prefab management, and full Creative Suite access.

The 26 ScriptTools handle C# script creation with Roslyn analysis that catches syntax errors before the file hits disk. The AnimTools create Mecanim controllers from descriptions -- ask for a locomotion blend tree and Manny builds the state machine, adds the states, sets up transitions with parameter conditions, and assigns your animation clips. Material creation adapts to your active render pipeline, whether that is Built-in, URP, or HDRP.

Manny takes his work seriously. He is, after all, a professional -- even if he happens to be a skeleton in a nice suit.

76+ Tools, 9 Providers

Both plugins share the same tool architecture organized into four categories:

• Core (7 tools) -- diagnostics, asset search, caching, and transaction undo
• ScriptTools / BlueprintTools (26 tools) -- code generation, scene management, prefabs, materials, input configuration, and batch operations
• AnimTools (6 tools) -- state machines, transitions, blend trees, clip assignment, and validation
• AI Router (18+ tools) -- LLM chat, image/texture generation, 3D mesh generation, audio generation, Blender MCP integration, and provider management

The AI Router supports 9 providers out of the box: Claude, Gemini, and OpenRouter for LLM tasks; DALL-E and Stable Diffusion for images; Meshy and Hyper3D for 3D models; ElevenLabs and Suno for voice, music, and sound effects. The router automatically selects the right provider for each task type, or you can override and pick a specific model.

Everything runs on the Model Context Protocol (MCP), which means you can also connect Claude Code or Claude Desktop to your editor and use Blueprint Factory tools from your terminal or desktop app.

Pricing

Blueprint Factory uses a tiered model that starts free:

• Core (Free) -- AI chat, 3 LLM providers, 10 essential tools, and basic project planning. No time limit.
• Pro ($29/month per seat) -- all 76+ tools, all 9 providers, Creative Suite, and priority support.
• Team ($49/month per seat) -- everything in Pro plus shared plans, team memory, collaboration, and dedicated support.

The free tier is not a trial. It is a fully functional product that gives you AI chat and the most-used tools. Upgrade when you need the full toolset or Creative Suite capabilities.

Getting Started

Installation takes under five minutes for either engine:

• Unity: Add the Manny package via Package Manager from git URL or download from the Asset Store. Open the dashboard from Window > Manny > Dashboard, configure an API key, and start chatting.
• UE5: Install BlueprintForge from the Marketplace or drop the plugin into your Plugins folder. Open the dashboard from Window > BlueprintForge > Dashboard.

Full setup instructions are in the Getting Started guide, and the complete Tool Reference documents every tool with parameters and descriptions.

What Comes Next

This launch is the beginning. Here is what we are working on for upcoming releases:

• Visual scripting integration -- deeper graph editing for UE5 Blueprints and Unity Visual Scripting
• Multiplayer project support -- real-time collaboration where multiple team members share a single AI context
• Custom tool authoring -- define your own MCP tools that plug into the Blueprint Factory ecosystem
• Expanded Creative Suite -- video generation, terrain sculpting, and procedural level layout
• On-premise LLM support -- run local models via Ollama or LM Studio for air-gapped environments

We are building Blueprint Factory because we think AI automation should live where developers work, not in a separate browser tab. If you have been looking for a way to accelerate your game development workflow with AI, we built this for you.
