Can anyone help with Tobii Eyetracker 4C?

[WonkoTheSane]

I recently read that this game supports Tobii 4C, and wanted to give it a try.
I followed the instructions given in the games forums (start SteamVR, Helmet Camera, Windowed Mode,...) but still the game does not pickup eye or head movement. The Gaze Trace of Tobii works in the game, but there is no movement.
Is there any setting I missed, to make it work?
Thanks for your help in advance

You can set the Tobii range options in the game properties to almost eliminate eye tracking.

To do this you would right click on, for example, Automobilista 2 in Steam and select properties.
Then in the General tab look for 'set launch options'
Then add this line in to the field, NOTE you must include the - mark as well.
-TobiiEye 0.1 0.1

There will still be eye tracking but very minimal so that you can look at UI or apexes.
You can further tinker the -TobiiEye command line by adjusting the numbers.
Bishopsgambit gives a nice explanation of it in the above posts.

Thanks m8, I found this info in a pcars 2 thread and it works a treat :)

I ran into a similar problem. I couldn't get my Tobii Eye Tracker 5 to work while running FaceTrackNoIR in the background with Project Cars 2. One remedy is to uninstall it, yes, but a simpler option, I discovered, is to go into FaceTrackNoIR, under Game Protocol, and then click on Settings for FreeTrack 2.1, and Select Interface to Use FreeTrack, hide TrackIR (to prevent a conflict in some games including Project Cars 2). And then FaceTrackNoIR can keep running, with Tobii5 Tracker selected for Tracker Source, and the program even running Started. Then Tobii will work for all games that support it natively, and then it'll also work for those that support only TrackIR (with Tobii stepping in as a substitute).
