Blueprints are code under the hood, you can copy and paste them in plaintext and there are online blueprint readers that understand it’s format, such as blueprintsue.
an llm would need to be trained to output code compatible with such a reader and then output it into a webui that contains such a reader.
If you can get an LLM to output usable blueprint code that you could copy and paste into UE, then you would just need a webui that auto detects such code via it’s headers and displays it as nodes.
Essentially blueprints tend to begin and end like this in text form, which can be used for auto-detection:
Begin Object Class
...
End Object Class
No idea if anyone’s done it, it shouldn’t really be that hart, the tricky part is teaching an llm to write blueprint code. Or any code for that matter, i’ve tried to use things like chatgpt as programming aids in the past, and I found that unless you’re asking it things of the level of “how to make a for loop in langauge x” it’s useless.
