Installation

import { Steps, Aside } from ‘@astrojs/starlight/components’;

From the Fab Marketplace

1. Purchase BlueprintAI from the Fab Marketplace.

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

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

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

5. Restart the editor. BlueprintAI runs setup.py automatically on first launch and installs skills for all detected AI services.

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 → BlueprintAI.

4. Restart the editor.

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, or you want to target a specific AI service:

# Install skills for all detected services
python Plugins/BlueprintAI/setup.py

# Install only for Claude
python Plugins/BlueprintAI/setup.py --service claude

# Remove all installed skills
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.
