Note on Deployment platforms:

Viz Vectar plus is designed to take advantage of the hardware accelerated capabilities of the latest versions of Windows. Because of this, the Live Call Connect feature requires Windows Build 29041 or later. For some cloud platforms like AWS, this might not be available as default configuration. This will change over time. You can in most cases work around this by bringing your own Windows 10 version and deploying it manually in the cloud platform. This may have implications on cost, technical complexity and licensing agreements with Microsoft. This manual process is not supported by Vizrt. However, we do support our software.
