Varjo Reality Cloud feature support

When developing applications for Varjo Reality Cloud, not all the same features are supported as with desktop applications. Here is a reference list of the features that are supported.

Please note that if some feature is not available in the rendering engine, it is not available for that engine in Varjo Reality Cloud either. For more information on engine-specific feature support, see supported features.

1) All keystrokes are supported except Alt+Tab and Alt+F4. VRED hotkeys are supported.

2) The developer needs to implement a networking system with cloud based orchestration (no peer-to-peer connection), and the functionality to create and join sessions must be operated through the user interface in the VR app.

Varjo Reality Cloud Unity and Unreal Engine developer recommendations

  • Since the applications only render to headset, all the user interfaces should be immersive. Buttons or instructions in the 2D monitor window should be avoided as that window is not seen by a cloud user.
  • Keyboard or motion controllers are recommended for interaction.
  • Applications don’t need a specific quit function. When an application shuts down or crashes, it is restarted automatically.
  • Third party plugins and assets may not be compatible with the cloud setup. It is recommended to test them in isolation to see how they behave.
  • When an application is running in the cloud, you can use the Varjo Analytics window to see advanced statistics for performance debugging. To toggle statistics on and off use the F1 key.
