Blueprint Graph Exporter

Module: Tech · Category: QA · Tool ID: BlueprintGraphExporter

Three-tab Blueprint graph exporter. Single Export exports one Blueprint to JSON or Markdown. Batch Export scans and exports all Blueprints in a folder. Graph Viewer inspects graph structure with color-coded node categories. Useful for documentation, code review, archival, and Git-friendly Blueprint diffs.

Exporter on Single Export tab with a Blueprint loaded, format set to Markdown, graph + node count visible.

When to use it

• Generating Blueprint documentation for a wiki or design doc
• Code review of Blueprint changes (Git can’t diff .uasset meaningfully; Markdown export is human-readable)
• Archival: preserving Blueprint logic outside UE
• Quick graph inspection without opening the BP editor

What it isn’t for

• Don’t expect this to round-trip. Export-only; no import-from-JSON.
• Don’t expect graph rendering. Text/structural export only.

Opening the tool

1. Open the EQLabs Hub and search for Blueprint Export (or browse to Tech → QA).
2. Click the tool card.
3. Use the tab bar: Single Export / Batch Export / Graph Viewer.

Tab 1: Single Export

Field	What it does	Default
Blueprint picker	The BP to export	(empty)
Format combo	JSON / Markdown	JSON
Include Comments	Include comment nodes	true
Include Variable Values	Capture default values	false
Output Path	Save destination	(configurable)
Export Graph	Writes the file
Open Output Folder	Opens the folder in file explorer

Tab 2: Batch Export

Field	What it does	Default
Batch Scan Path	Folder to scan	/Game
Format combo	JSON / Markdown
Scan Blueprints	Walks the folder
Export All	Exports every BP in the list
Export Selection	Exports only checked rows
Batch list	Per-BP row: name, graph count, node count, exported flag

Tab 3: Graph Viewer

Field	What it does
Blueprint picker	The BP to inspect
Graph combo	Pick a graph within the BP
Nodes list	Per-node: title, class, category (Event / Function / FlowControl / Variable), pin count
Copy Node Summary	Plain-text dump

Color-coded node categories make graph structure easy to read at a glance.

Workflow

Document a single BP

1. Switch to Single Export.
2. Drop the BP, pick Markdown format.
3. Set Output Path, click Export Graph.
4. The Markdown file is human-readable for wikis / pull-request descriptions.

Batch document a folder

1. Switch to Batch Export.
2. Set Scan Path, click Scan Blueprints.
3. Click Export All for the whole folder, or select rows + Export Selection.

Quick inspection

1. Switch to Graph Viewer.
2. Drop a BP, pick a graph.
3. Read node list with color-coded categories.

Settings reference

Per-tab settings persist to [Project]/Saved/EQLabs/Settings/BlueprintGraphExporter.json.

Output

• JSON files. Structured representation of the graph.
• Markdown files. Human-readable summary.
• In-panel graph viewer. Read-only inspection.
• No BP edits. Export-only.

Tips and gotchas

• Markdown is best for code review. Human-readable, Git-friendly, can be embedded in PR descriptions.
• JSON is best for tooling. Feed into custom dashboards or analysis tools.
• Variable values capture is optional. If your BP has sensitive defaults, leave it off.
