How to Use Luma AI for 3D Capture

Learn to capture stunning 3D models with Luma AI. Step-by-step guide covering setup, recording techniques, and processing for photorealistic results.

1. Download and install Luma AI. Download Luma AI from the App Store on your iPhone 12 or newer. The app requires iOS 15.0 or later and uses your device's LiDAR sensor for enhanced depth mapping. Open the app and create an account using your email or Apple ID.
2. Position your subject for optimal capture. Place your subject in well-lit conditions with even lighting from multiple angles. Avoid direct sunlight or harsh shadows that create high contrast areas. Ensure the subject sits on a stable surface with enough space to walk completely around it in a 3-4 foot radius.
3. Configure capture settings. Tap the Settings icon and select your desired quality level. Choose High for detailed objects under 2 feet, Medium for furniture-sized items, or Low for quick previews. Enable Grid Lines to help maintain consistent framing throughout your capture session.
4. Record your capture video. Tap the record button and walk slowly around your subject in a complete circle, keeping the object centered in frame. Move at roughly one step per second while maintaining a consistent distance from the subject. Record for 20-60 seconds depending on object complexity.
5. Upload and process your capture. Tap the checkmark when finished recording. The app automatically uploads your video to Luma's cloud servers for neural processing. Processing typically takes 10-30 minutes depending on video length and current server load. You'll receive a notification when complete.
6. Review and refine your 3D model. Open your processed capture from the Gallery tab. Use pinch gestures to zoom and drag to rotate the 3D model. Check for missing geometry or texture issues, particularly on the bottom surface that wasn't captured. Tap Edit to crop unwanted background elements or adjust the model's orientation.
7. Export your 3D model. Tap the Share button and choose your export format. Select USDZ for iOS AR experiences, OBJ for 3D modeling software like Blender, or GLB for web applications. The app generates multiple quality levels automatically, with higher polygon counts available for Pro subscribers.
