World Tracking and Calibration

World Tracking uses ARCore to send the phone's physical position and orientation to Blender. It requires an ARCore-compatible device, camera permission, adequate lighting, and a trackable environment.

Calibrate Before Tracking

  1. Enable World Tracking from the Controls mode bar.
  2. Allow camera access when Android asks.
  3. Move the phone slowly so ARCore can identify a stable ground reference.
  4. Keep the phone steady while tracking stabilizes.
  5. Optionally align the phone pitch and roll with the Blender camera guide.
  6. Start World Tracking when the overlay reports that tracking is ready.

Tuning and Recovery

Use World Scale and Extra Multiplier in Motion and Tracking Settings to match the physical movement to the scene scale. Use Reset Position or Reset Rotation when a new reference is needed. Lock Height and Horizon Lock can help keep a shot constrained.

Environment quality matters

Low light, plain walls, reflective surfaces, and fast movement reduce ARCore tracking quality. Point the phone toward textured objects or corners and move more slowly.

The Demo build may limit an active World Tracking session. For support problems, use Sensor and World Tracking Troubleshooting.
