Hello,
Have you ever copied Blueprint logs or screenshots into ChatGPT, hoping it would help you debug?
However, this approach often proves to be inaccurate or overly complex.
This time, I experimented with “What if we send the actual structure of the Blueprint (as JSON) to GPT?”
Summary of the Experiment:
-
Automatically collected node structures, pin connection information, error messages, etc., from Blueprints
-
Organized them into structured JSON and sent to GPT
-
GPT analyzed the “structure” instead of logs to provide insights into error causes and suggested fixes
Results:
I received much more specific feedback than expected.
It was even able to point out issues like “incorrect pin connections” or “event node order seems off.”
The most surprising part was that this was all done directly within the editor.
Tool Used:
A plugin I developed:
GPT for Blueprint Debugging
(Supports UE 5.4.4 and 5.5.4, requires OpenAI API key)
Questions:
-
What methods do you primarily use for debugging Blueprints?
-
If you were to use structure-based debugging, what additional features would you like to see?
Your feedback and experiences are invaluable.
Thank you.
