🔥 About

Yes, you heard that right. Generate Blueprints using AI.

This project has been a labor of love for over a year and a half. As a solo developer, I took it from a simple idea, through early concepts, to a working prototype. Now it’s in beta release. The journey hasn’t been easy, but it’s been full of valuable lessons that helped shape the product into what it is today.

While AI-powered Blueprint generation is the core feature, there’s much more to explore. Check out the product pictures to see what’s possible. And this is just the beginning. I have many exciting features coming soon 🙂

 

🏆 Features

• Fast Generation: Functions are generated in just 5–10 seconds ⚡
• Cost-Efficient: Use the Gemini API for free, or get up to ~3,300 function generations per $1 with OpenAI 🪙
• Source Code: The full source code is available for transparency and educational purposes. Sharing, making it public, reselling, or redistributing in any form is strictly prohibited and will result in legal action 🔓
• User-Friendly: Easy to use with clear and well-written documentation 🤓
• Actively Maintained: Regular updates with new features and improvements 🔄
• Structs and Enums: The AI automatically creates Structs and Enums it needs
• The AI is able to answer in any language! Besides English, you can change the UI language to French, German, Russian, Spanish, Korean, Japanese, Simplified Chinese & Traditional Chinese. For AI answers you can choose any language you want 🙂

 

❓FAQ

Does this support Local LLM’s?

Not yet. I plan to add support for Local LLM ‘s very soon

⭐Current Status & Roadmap

This tool is continuously being developed and improved. Thanks to the community’s feedback, I’ve fixed all known major bugs from the early versions and significantly increased the quality of the generated output. I am currently working on new features (e.g., support for additional LLMs and platforms) and welcome your ideas. Help us make the tool even better! The plugin is also still undergoing massive improvements to the quality of generations.

 

📝 Note 😇

Hey there,

Thanks for considering my plugin! With your purchase, you’ll receive the full source code and premium quality support. Feel free to use it for both commercial and non-commercial projects. However, please note that reselling the plugin is not permitted. We strongly advise against using cracked versions from dubious sites; they’re risky, illegal, and offer no guarantees. The FAB Marketplace is the only website where you can legally download this plugin. Thank you for supporting indie developers like me!

 

Please note that Fab plugins use a per-seat licensing model.

 

❗Disclaimer

This plugin is not affiliated with, endorsed by, or sponsored by OpenAI or Google in any capacity. It communicates with the OpenAI and Gemini APIs solely through standard HTTP requests based on the user’s input.

 

An active OpenAI or Google account is required, along with an API key. Please be aware that API usage is a paid service subject to the pricing, terms of service, and privacy policies of the respective provider (OpenAI or Google). Users are fully responsible for any costs incurred.

 

The plugin does not include, host, or provide any AI models itself. Instead, it sends user prompts to the selected AI service (OpenAI or Google Gemini) and processes the AI-generated responses inside Unreal Engine. This enables the generation of Blueprints, code, or other Unreal Engine content based on the AI’s output. The plugin acts purely as an interface that transforms AI responses into usable assets or tools within Unreal Engine.

 

⚠️ AI-Generated Content Warning:The output generated by the AI may be incorrect, incomplete, unpredictable, biased, offensive, or harmful. The user is solely responsible for reviewing, testing, and validating any AI-generated content (including code, blueprints, or text) before using it in any project. The developer of this plugin assumes no liability for any damages, losses, or issues arising from the use of AI-generated content.

 

This is a beta release. Bugs, errors, or crashes may occur. Users are encouraged to report any issues encountered during use.

A comprehensive setup tutorial is included to assist with obtaining and configuring API keys.
