Blueprint Export

Export Blueprints from a running UE5 Editor via Python remote execution.

What the User Needs

1. UE5 Editor running with their project open
2. Python Remote Execution enabled (run /ue5-blueprints:setup if not done)
3. Blueprint path(s) to export

Steps

1. Get the Blueprint Path(s)

Ask the user for the Blueprint path(s) they want to export. These look like:

• /Game/MyProject/Blueprints/BP_PlayerCharacter
• /Game/MyProject/UI/WBP_MainMenu

They can find this by right-clicking any asset in the Content Browser and choosing "Copy Reference".

2. Choose Export Type

• T3D Export — Raw text export with ALL node data including pin connections. Best for deep analysis and wiring map generation. Larger files.
• Graph Snapshot — Structured JSON with node types, variables, functions, positions. Smaller, faster, good for quick audits.
• Both — Full pipeline for maximum analysis power.

3. Create the Target Config

Write a JSON config file for the export scripts. Use ${CLAUDE_PLUGIN_DATA} for output:

For T3D export, write to ${CLAUDE_PLUGIN_DATA}/export_targets.json:

[
  {"path": "/Game/...", "output": "MyBP.t3d"}
]

For snapshot, write to ${CLAUDE_PLUGIN_DATA}/snapshot_targets.json:

[
  {"path": "/Game/...", "output": "MyBP_snapshot.json", "graphs": ["EventGraph", "MyFunction"]}
]

Set "graphs" to null to export ALL graphs in the Blueprint.

4. Run the Export

Set the output directory and run:

UE5BP_OUTPUT_DIR="${CLAUDE_PLUGIN_DATA}" python "${CLAUDE_PLUGIN_ROOT}/scripts/run_in_editor.py" "${CLAUDE_PLUGIN_ROOT}/scripts/bp_export_t3d.py"

Or for snapshot:

UE5BP_OUTPUT_DIR="${CLAUDE_PLUGIN_DATA}" python "${CLAUDE_PLUGIN_ROOT}/scripts/run_in_editor.py" "${CLAUDE_PLUGIN_ROOT}/scripts/bp_snapshot.py"

5. Confirm Results

Read the output files to verify export succeeded. Report file sizes and node counts to the user.

Suggest next steps:

• /ue5-blueprints:blueprint-audit to analyze the exported data
• /ue5-blueprints:blueprint-check for a quick paste-and-check
