A. onAirVR Client plugin is not publicly available for now. Please contact us via contact@onairvr.io then we can discuss what we can do.

Q. My game engine fails to load onAirVR Server plugin.

A. It might be due to missing libraries which onAirVR Server depends on. Check out the system reqirements:
the latest NVIDIA graphics driver, CUDA Toolkit 8.0.

Q. onAirVR App keeps failing to connect.

A. Windows Firewall may block inbound connections to your game engine editor or application you built. Please check Windows Firewall settings and set to allow inbound connections – both TCP and UDP.

Q. Succeeded to connect but the display of onAirVR App is black or green.

A. Update NVIDIA graphics driver of your PC to the latest one. It is worth noting that CUDA Toolkit installation might force to install an older version of NVIDIA graphics driver. If it happens you must update the driver after the installation.

Q. I can see my application scenes on onAirVR App but the video frames are often distorted or dropped.

A. If your PC runs your application well enough, it is due to the performance of your wireless network in most cases. There are several things you need to check:

  • We recommend to use a 5GHz Wi-Fi router. It provides more stable data transmission than 2.4GHz according to our experience in various use cases.
  • Change the channel of Wi-Fi in your router setting. Do not use channels which your neighbors’ routers
    are already using.
  • Hide the Wi-Fi SSID on the router setting. In crowded environments, it helps the router to avoid interference from people’s portable devices searching an available Wi-Fi.
