Installation

From the Fab Marketplace

1. Purchase Blueprint AI from the Fab Marketplace.

2. Open the Epic Games Launcher, go to Library → Fab Library, and find Blueprint AI.

3. Click Install to Engine and select your UE 5.7+ installation.

4. Open your project, go to Edit → Plugins, search for Blueprint AI, and enable it.

5. Restart the editor. Blueprint AI runs setup.py automatically on first launch and installs the Claude skill.

From Source

1. Clone or copy the BlueprintAI folder into your project’s Plugins/ directory.

2. Run the third-party setup script once before building:

   python Plugins/BlueprintAI/Scripts/install_thirdparty.py

   This downloads the gitignored native binaries (ripgrep) listed in third-party.json.

3. Enable the plugin in Edit → Plugins → Blueprint AI.

4. Restart the editor.

Note

The Fab zip already ships with all third-party binaries pre-bundled. The install_thirdparty.py step is only needed for source installs.

Running setup manually

If automatic setup did not run:

# Install the Claude skill
python Plugins/BlueprintAI/setup.py

# Remove the installed skill
python Plugins/BlueprintAI/setup.py --uninstall

Verifying the installation

Open a terminal in your project root and run:

python Plugins/BlueprintAI/Scripts/cli.py schema

You should see a list of all registered operations. If the output is empty or an error appears, check that PythonScriptPlugin and EditorScriptingUtilities are enabled.
