Blueprint Operations

AI-Powered Blueprint Export, Analysis, C++ Generation & Visual Inspector for UE

What is Blueprint Operations?

Export Blueprints to JSON, analyze with AI (Ollama/OpenAI/Gemini/DeepSeek/Kimi and many more), generate C skeletons, visual graph inspector. 244 C files. 100% standalone.

Overview

Blueprint Operations is the most comprehensive Blueprint utility toolkit for Unreal Engine. It bridges the gap between visual scripting and text-based workflows by exporting Blueprint graphs to structured JSON, enabling AI-powered analysis, generating placeholder C++ code, and providing a full visual graph inspector — all from the Content Browser context menu or a dedicated editor window.

Whether you’re documenting your Blueprint architecture, migrating to C++, leveraging AI assistants to understand complex graphs, or inspecting Blueprint data in a rich visual UI, Blueprint Operations streamlines your entire workflow without ever leaving the editor.

Built with 244 C++ source files and over 20,000 lines of hand-written code — this is one of the largest and most feature-rich Blueprint tools available.

Key Features

Blueprint Export System
- Export any Blueprint asset’s graphs and variables to clean, structured JSON
- Copy JSON directly to clipboard for instant sharing with AI tools
- Recursive folder export for batch processing entire projects
- Optional AI Context metadata for richer analysis
- Configurable output format and directory structure

AI-Powered Analysis — 3 Providers
- Send Blueprint JSON directly to AI providers from the Content Browser
- Supports Ollama (local LLM), OpenAI (GPT-4o, GPT-4), and Google Gemini
- Customizable prompt prefix and format templates
- Automatic code block extraction from AI responses (.h / .cpp pairs)
- Save AI responses to disk for documentation and review
- Batch AI analysis for entire folders

C++ Code Generation
- Generate placeholder C skeleton files from Blueprint JSON
- Structural approximation of Blueprint classes, functions, variables, and pin connections
- Advanced pin type resolution with literal resolvers, macro resolvers, and pure function resolvers
- Batch generation with recursive folder support
- Perfect starting point for Blueprint-to-C migration projects

Visual Blueprint Inspector
- Dedicated editor window with multi-panel layout (splitter-based)
- Browse exported Blueprints with syntax-highlighted JSON viewer
- Color-coded data visualization with custom syntax colorizers
- Action panel with one-click export, analyze, and generate buttons
- Feature checklist showing which operations are available per Blueprint

Developer Experience
- Seamless Content Browser integration via right-click context menu
- Organized output directory (Saved/BlueprintOperations/)
- Configurable via Project Settings (UDeveloperSettings)
- Detailed logging with dedicated categories (LogBlueprintOperations, LogBlueprintOpsAI)
- Command palette integration for quick access

Zero External Dependencies
- No dependency on any other HudHud Games plugin
- Fully self-contained — install Blueprint Operations alone and it works perfectly
- Optional: works great alongside AI Chat for sending Blueprint data to AI conversations
