Eye Tracking FW vs. SteamVR Watchmen Firmware
When the Vive Pro Eye is plugged into your PC and SteamVR is running it may offer updates to the Vive Pro watchmen tracking modules. Feel free to update these as suggested by SteamVR.
There is a seperate firmware for the eye tracking modules. Only update the eye tracking firmware if you have an older dev kit that requires an update to work with the latest runtimes.
Instructions:
- Unzip update_xxxx.zip
- Run update.bat
- Wait for the update to complete
- Do not unuplug the Vive Pro Eye or interrupt the firmware update process!
Right click the SRanipal notification icon and select "About" you should see the "Runtime Version: 0.7.2.1" and "Eye Camera Version: 1.88.0-8106667"
If the Vive Pro Eye is unplugged or if you are using a devkit with an older firmware it may show the eye camera version as "N/A".
If you are using a devkit with an older firmware it may be incompatible with the latest runtimes and will require a firmware update to work properly.
If you are having further issues with the eye tracking please reach out to your HTC contact for support or post the issue in the forums.
Please see the troubleshooting guide here:
The only differences are with "expression_data", which supports more facial expression blendshapes.
