I think you are thinking of TOGGLE HEAD TRACKING and it currently unbound so you need to bind a key to it however when turning TOGGLE HEAD TRACKING off it resets the view to looking straight forward so I’ve written a workaround that you can use here(it will keep your view where you are currently looking at): https://forums.flightsimulator.com/t/making-tobii-eye-tracker-work-with-su8/472111/252.
F12 is the new hidden function to Center/Reset your tracker. The fuss over F12 are two different issues:
- F12 is the default key to take a screenshot in Steam and so it will interfere with trying to Center/Reset tracking.
- F12 is a hidden function that is not exposed in the CONTROLS OPTIONS in keyboard settings(try pressing F12 in the SEARCH BY INPUT textbox and only LIVERIES will appear). For any custom keyboard profiles made prior to SU8 the F12 key will not work so you need to change it back to a default profile first and then you can edit your custom keys. Alternatively you could hand edit your custom input profile config file and add the hidden F12 function by following the guide posted here: https://forums.flightsimulator.com/t/making-tobii-eye-tracker-work-with-su8/472111/242. You can also change this hidden F12 function to a different key if you hand edit the input profile config file by following the guide posted here: https://forums.flightsimulator.com/t/making-tobii-eye-tracker-work-with-su8/472111/242
