Help with headtracking please

Hello guys, I'm trying to use head tracking with the game (last version) but I can't get to make it work. I'm using the opentrack software, also I did try it with aitrack together but in both ways it doesn't work for me... Open track works, the octopus follows my heads movements but Automobilista 2 not, using the helmet cam. I've started the game on Steam VR mode and also on Oculus VR mode with no results... I've tested it in ACC and works without doing something else.
There is some in game configuration I'm missing? Do I have to install Steam VR or configure something else on Steam app? I'm on Windows 10 and using a hd webcam. Any help would be appreciated, thanks in advance!

 

Also I've seen when I start the game from Steam on both Steam or Oculus VR mode, these options are disabled in my settings screen as the image bellow shows. I don't know if this has something to do with the issue...

 

Mine only works in steam vr mode but steam vr needs to be closed [ not running ] when I start ams2 it then starts with the ams2 .If steam vr is already running it does not work .Also only works in helmet cam

 

Thanks for your answer, I don't have steam vr installed on my computer. Do I have to install it?

 

I did install Steam VR but still not working. Am I missing some extra settings maybe?

 

I can't think of any other settings apart from having steam vr running in the background and changing view to helmet cam .It just works for me

 

Then I have no idea why is not working... Anyway thanks so much for your help

 

Solved, finally. Was the Windows firewall that was blocking the opentrack app. Now it's working perfect!

 

Your persistence has paid off! I would never have believed the firewall could effect it .Well done .
