Scanning Troubleshooting
1 . Crashing or failing to run the scan application : a . Check the hardware compatibility and iOS on your device . Try deleting and reinstalling the application from the app store . Take care to upload your local data first . 2 . Cannot capture the scan or track well .: a . Make sure you are an appropriate distance from the target . i . TrueDepth works best at 30-40cm from the target surface although this can vary by device . Going too close or too far away can reduce accuracy and tracking of the target object . b . Check the environment i . The devices use Infrared sensors and Infrared projection so they can be sensitive to lighting where there is interference from IR . This can happen in daylight and in some incandescent or halogen lighting . Try another location or draw blinds . ii . Some materials unusually reflect IR when lighting conditions are poor . Scanning bright white plaster , for example , can be temperamental . Try to alter the lighting conditions . c . Change the target box i . The virtual box on the screen where the scanning is done will allow you to zoom in or out if you pinch two fingers on the screen at the same time to increase or decrease the size of the scanning target box
