Node to Code transforms your Unreal Engine Blueprint graphs into clean, structured C++ with a single click. Stop spending hours on tedious manual conversions, struggling to explain complex visual logic, or navigating sprawling Blueprint systems. This LLM-powered plugin bridges the Blueprint-to-code gap, whether you're optimizing performance, improving collaboration, or learning/teaching the Unreal Engine C++ API.
- 🆕 Support for Claude 4, Gemini 2.5 Flash, & OpenAI's latest models
- 🆕 Support for LM Studio -> Quick Start Guide
- 🆕 Complete Blueprint Translation: Translate entire Blueprints with all graphs, variables, and components at once
- 🆕 Variable & Component Support: Full support for Blueprint variables, local variables, and component overrides
- Pseudocode Translation: Convert Blueprints into universally understandable pseudocode
- Automatic Translation Saving: Each translation is saved locally for easy archiving & sharing via chat or docs
- Share complete Blueprint logic as text in forums, chat, emails, or documentation
- No more endless screenshot chains or lengthy meetings to explain systems
- Perfect for remote teams, forum help requests, and collaborating with AI assistants
- Transform sprawling node networks into clear, structured text
- Capture entire Blueprint hierarchies with configurable depth (up to 5 levels deep)
- Spot patterns and relationships that are hidden in visual spaghetti
- See your own Blueprint logic translated to proper Unreal C++
- Learn from implementation notes that explain key concepts and patterns
- Use your existing code as reference to influence translation style
- Compare multiple language outputs (C#, JavaScript, Python, Swift) to strengthen programming fundamentals
- Quickly translate performance-critical Blueprint systems to C++
- Keep prototyping rapidly in Blueprint, knowing you can convert bottlenecks later
- Avoid the tedious manual conversion process that takes hours or days
- Create searchable text archives of your Blueprint systems
- Preserve design decisions in formats accessible to everyone on your team
- Generate code snippets for technical documentation or requirements
- Blueprint Analysis: Captures your entire Blueprint graph structure, including execution flows, data connections, variable references, and comments
- Complete Blueprint Translation: Translate entire Blueprints with all graphs, variables, and components in a single operation
- Variable & Component Support: Full support for Blueprint-level variables, local variables, and component property overrides
- Multiple LLM Options: Use cloud providers (OpenAI, Anthropic Claude, Google Gemini, DeepSeek) or run 100% locally via Ollama for complete privacy
- Efficient Serialization: Converts blueprints into a bespoke JSON schema that reduces token usage by 60-90% compared to UE's verbose Blueprint text format
- Style Guidance: Supply your own C++ files as reference to maintain your project's coding standards and patterns
- Integrated Editor Experience: Review translations in a dockable Unreal editor window with syntax highlighting, implementation notes, & theming
- Blueprint Creators: Communicate systems clearly and gradually learn C++ through your own work
- C++ Programmers: Understand designer intent without deciphering complex visual graphs
- Project Leads: Improve team communication and maintain better system documentation
- Educators & Students: Bridge the visual-to-code learning gap with real examples
- Translate Entire Blueprint: New toolbar command to translate all graphs in a Blueprint at once
- Batch Processing: Each graph generates independent JSON and LLM requests, all sharing the same root directory
- Error Feedback: Comprehensive success/failure reporting for batch translations
- Blueprint Variables: Full support for Blueprint-level variables with complete type mapping (including Array, Set, Map)
- Local Variables: Function-level local variable collection and serialization
- Component Overrides: Automatic detection and serialization of component property overrides
- Component Hierarchy: Support for component parent-child relationships
- Map Key Types: Improved Map key type extraction from Blueprint pin types
- Class Structure Marking: New graph type for representing class skeleton structure
- C++ Class Generation: Enables LLM to generate proper C++ class declarations, constructors, and member variables
- Conditional Creation: Automatically created when variables or components are present
- Enhanced Prompts: Significantly expanded CodeGen_CPP.md with detailed guidance for components, variables, class structures, event handling, and network replication
- Better Type Mapping: Improved handling of complex Unreal Engine types
