Distribution of your created content in CenarioVR is done by adding viewers to your account, and assigning that content to them. Once that viewer has been created and content has been assigned to them, the user logs into the CenarioVR app either on the web, on a phone, or on a VR headset (such as the Quest) and the content will be downloaded and run from the device.
The licensing model is by author and by viewers. A single Pro licence gives you one author, and 250 viewers. That’s 250 named people you can assign content to, and track results for.
Publishing off of CenarioVR, such as to HTML or SCORM, does not require having named users, as it is not using the services of CenarioVR for distribution of the content.
