Introduction: Blueprint to C++ Converter

This powerful Unreal Engine editor tool is designed to accelerate your project's transition from Blueprint prototyping to performant C++ implementation. It automatically converts your Blueprint classes, structs, and enums into ready-to-use C++ code, streamlining the development process.

Key Features

• Automated Code Generation:​ Seamlessly converts Blueprint classes, User Defined Structs, and User Defined Enums into native C++ code.

• Unreal Engine Compliant:​ Generates both header (.h) and source (.cpp) files that adhere to standard Unreal Engine coding conventions.

• Macro Expansion Support:​ Handles macro nodes by expanding their internal logic into corresponding C++ code.

• Batch Processing:​ Save significant time by converting multiple Blueprint assets to C++ simultaneously.

• Advanced Path & Module Management:

  • Configurable output paths (Detailed​ or Unified Global​ paths) with separate public/private directories for headers and source files.

  • Automatically updates relative #includepaths in generated header files.

  • Intelligently organizes output by separating runtime module and editor module Blueprint classes.

  • Shared assets (structs, enums, interfaces) referenced by both runtime and editor modules are automatically placed in a common module.

• Code Preview & Display Control:

  • Supports code preview with syntax highlighting (note: highlighting may not be completely accurate).

  • Flexible display settings, including horizontal/vertical layout, font style, font size, read-only/edit modes, and configurable syntax highlighting colors.

  • Automatically updates code when the source asset is modified.

Important Notes & Limitations

While this tool is highly effective, it is essential to be aware of its limitations. The generated code often requires manual review and adjustment, especially for non-standard Blueprints.

1. Architectural Complexity:​ The tool works best with standard Blueprint architectures. Complex structures​ featuring advanced node networks, custom macros, or intricate inheritance may generate code with structural errors that require manual correction.

2. Automatic Prefix Removal:​ The tool automatically strips common Blueprint prefixes (e.g., BP_, BPI_) from names. You must ensure that names remain unique after prefix removal​ to prevent code file overwriting and naming conflicts.

3. Missing/Incorrect Includes:​ Generated code may have missing or incorrect header file includes and module dependencies.​ You must manually check and add these includes for the code to compile correctly.

4. Code Preview Crash:The code preview feature is prone to editor crashes during interactive clicks on empty characters. Testing reveals that the base class SMultiLineEditableText also exhibits this issue.

Disclaimer:​ Always thoroughly review the generated code before using it in production projects.​ It is critical to validate variable access patterns and the correctness of the execution flow. This tool is an assistant to speed up development, not a substitute for a programmer's review.
