Is there any tutorials or unity sense about how to use device api to select different camera?

Hello @suncongch

Do I understand correctly that you want to use two cameras in one application?

Unfortunately, at the moment, nuitrack does not support the use of multiple cameras in one project., but we can discuss it within a custom development contract if you’re interested. you can contact by email: tag@3divi.com
