Blueprint FlowTrace – Execution Tree Exporter turns sprawling Blueprint graphs into clear, text-based execution trees. Instead of scrolling through spaghetti, you get a compact, readable summary of what runs, in what order, and with which key values—ideal for reviews, documentation, and AI-assisted refactors.
This is an editor-only Unreal Engine plugin and the first tool in the FlowTrace suite of Blueprint utilities. Future updates will add new capabilities and support for upcoming Unreal Engine versions.
Key Features
Copy Entire Blueprint Hierarchy
Export a full Blueprint—events, functions, and graphs—into one organized execution report, copied straight to your clipboard.Copy Selected Nodes
Focus on the area you’re working on. Select any region of a graph and export only the relevant execution paths and variables.Smart Copy Shortcut (Ctrl + Alt + C)
One shortcut that “does the right thing”: copies selected nodes in an open Blueprint, or copies the hierarchy of a Blueprint selected in the Content Browser.Clipboard-first, zero-friction workflow
No new windows, no file management. Press the button, paste into your editor, issue tracker, documentation, or AI chat.Readable ASCII Execution Trees
FlowTrace follows exec wires and prints an indented tree using └, ├, │ and labeled edges like Then 0, True, and False, reflecting real execution flow rather than visual layout.Three Detail Levels
Compact: structural overview.
Normal: recommended default; adds important variables, enums, and expressions.
Verbose: maximum detail for deep debugging and documentation.
Inline Logic Expressions
Key operations are printed as simple statements so you can understand behavior without chasing wires.Globals, Locals, and Legend
Full exports include sections for global and local variables plus a legend explaining the notation—easy to share with teammates.
Designed For
Developers maintaining large AI, ability, or interaction Blueprints
Teams that need review-friendly text summaries instead of screenshots
Anyone who wants clean context for documentation or AI tools without re-explaining their Blueprint every time
Blueprint FlowTrace fits into your existing workflow as a small, reliable editor button: click, copy, paste, and get on with the real work.
