American Truck Simulator (Windows)

LookPilot Configuration

1. Set protocol to freetrack
2. Click Start to begin tracking

American Truck Simulator Setup

Head tracking should work automatically. If it doesn't respond, check the game's settings for a TrackIR or head tracking option that may need to be enabled.

Common issues

Game not reacting to tracking input even though the tracking is running

1. Make sure to have the line "uset g_trackir" set to "1" (including the quotes) in ../Documents/American Truck Simulator/config.cfg. Edit the file with the game closed - the game rewrites it on exit, which can undo your change. Some users report the value reverting even then; marking config.cfg read-only after editing has worked as a countermeasure (community-reported).
2. Bind a key in Keys and Buttons for "Enable Head Tracking" and try pressing it in-game.

Mouse-look stops working after closing LookPilot

A known issue in SCS titles: if the in-game camera stops following your mouse after you exit LookPilot, restart the game - mouse-look returns. Keeping LookPilot running for the whole session avoids it entirely.

If you want to stop using head tracking and hand camera control back to the mouse permanently, set uset g_trackir back to "0" in ../Documents/American Truck Simulator/config.cfg (edit with the game closed). Set it to "1" again when you next want head tracking.

Having to re-center constantly while driving

The most common ATS complaint. Three things fix nearly all of it: put the webcam dead-center under or above your monitor (not off to the side), recenter with Alt+C while sitting in your natural driving posture, and add a small center plateau to the yaw curve in Settings -> Tracking so highway posture drift does not accumulate into the camera.

Reducing jitter and shake

Shaky or twitchy tracking is the most-reported issue across all games, and it almost always traces to the camera picture, not the game:

1. Light your face from the front. Backlighting (a window or lamp behind you) starves the tracker of facial detail and produces micro-jumps.
2. Check your camera's real frame rate. Many webcams silently drop to 10-15 fps in low light even when set to 30. In LookPilot, watch the Tracker fps readout while tracking - if it is far below your camera's rating, more light usually fixes it.
3. Raise smoothing. In Settings -> Tracking, increase smoothing/filtering until stillness feels stable, then walk it back until the response feels quick enough.
4. Flatten the curve center. Give the response curves a gentle plateau around the center so breathing and small posture shifts do not move the camera.

Using a wheel or HOTAS alongside LookPilot

If your wheel or stick misbehaves while LookPilot runs (stiff force feedback, lost input), update LookPilot first - a past version caused stiff force feedback on some wheels and was fixed in an update. Then make sure the output protocol is freetrack rather than virtual joystick - the virtual joystick device can conflict with some wheel drivers. ATS reads the FreeTrack protocol directly, so the virtual joystick is not needed.

FAQ

Do I need TrackIR hardware? No - ATS reads the FreeTrack protocol, which LookPilot provides from a normal webcam. Together with ETS2, ATS makes up roughly two thirds of all LookPilot tracking hours, so the truck-sim path is the most battle-tested in the app.
