Abstract
In Unreal Engine, a popular game engine for AAA (high budget, high profile) title video games, Blueprint Visual Scripting is a widely used tool for developing gameplay elements using visual node and edge-based source code. Despite its widespread adoption, there is limited research on the intersection of software engineering and Blueprint-based visual programming. This dataset aims to address this gap by providing parsed Blueprint graphs extracted from Unreal Engine’s binary UAsset files. We developed extractors and a custom parser to mine Blueprint graphs from 335,753 Blueprint UAsset files across $\mathbf{2 4, 0 0 9}$ GitHub projects. By providing this dataset, we hope to encourage future research on the structure and usage of Unreal Engine Blueprints, and promote the development of tools—such as code smell detectors and language models for code completion-that can optimize visual programming practices within Unreal Engine.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
