The first thing to do is to check that Zu3D or Cloud Stop Motion has the correct camera selected.
You can choose which webcam Zu3D and Cloud Stop Motion uses by opening the settings and selecting your preferred connected camera - please note, you need to be working on a project to access your Camera Settings, so either open an existing project to edit, or create a new project in order to access the following relevant settings.
Zu3D Windows
Once you have a project open, go to the top menu bar and select: Settings > Camera Settings in order to choose the correct camera or make any changes to the settings as required
Zu3D Mac
Once you have a project open, go to the top menu bar and select: Settings > Camera Settings and tick the webcam you wish to use, or make any other changes to the settings as required
Cloud Stop Motion
Open an existing or new project and click the Camera icon located on the left hand toolbar to open the pop-out menu. From here select the Camera settings cog above the red Capture frame button and find your correct camera in the drop down menu. (Our HD Animation-Webcam usually displays as 'USB camera')
If you can't see the webcam listed, please check for any anti-virus software which may be blocking access to your webcam.
If you can see the webcam listed, but no image is displayed, please can you make sure that no other program is using it, for example Skype or a laptop's built in webcam software, and that any 'privacy' slide/cover located on the lens is open.
You can also try using the webcam in another program. On Mac you could try with Facetime, or on Windows you can download and use this Microsoft test utility AM Capture Download to see if your camera is recognised by your computer (please click the link in the comment to download the software).
If you do see the image in AM Capture or another program, but it is still not working in Zu3D or Cloud Stop Motion, please contact us providing as much information as possible about your camera and any error messages you receive, we will do our best to resolve the issue and get you back animating!
