Far Cry 6 Head Tracking

An unofficial head tracking mod for Far Cry 6 that moves the view with your head while your mouse or controller keeps aiming, driven by OpenTrack over UDP, with no VR headset required.

• Decoupled look and aim - your head moves the view, your mouse or controller keeps the aim
• Six-axis head tracking - yaw, pitch, roll and positional lean
• Works with any OpenTrack compatible tracker - free options available for PC, iOS and Android

• Far Cry 6 on PC, from Steam or from Ubisoft Connect. The PC Game Pass copy installs and launches through Ubisoft Connect, so it is the Ubisoft Connect build. The game folder must contain bin\FarCry6.exe and bin\tobii_gameintegration_x64.dll.
• Something that sends the OpenTrack UDP pose - OpenTrack itself with a webcam, or a phone app or hardware tracker configured to send that protocol.
• Windows 10 or 11, 64-bit.

There is no mod loader to install. The mod is a single DLL that takes the place of the head tracking library the game already loads, and the installer keeps the original beside it as tobii_gameintegration_x64.dll.backup.

Download Lopari, choose Far Cry 6, and click Play with head tracking.

1. Download the installer ZIP from the Releases page.
2. Extract it anywhere.
3. Double-click install.cmd. It finds the game, backs up the original library and copies the mod in.
4. Configure OpenTrack to output UDP to 127.0.0.1 on port 4242, as described under Setting Up OpenTrack.
5. Launch the game.

If the installer cannot find your game, point it at the folder yourself. Either set the environment variable, or pass the path as the first argument:

$env:FAR_CRY_6_PATH = 'D:\Games\Far Cry 6'
.\install.cmd

.\install.cmd "D:\Games\Far Cry 6"

Mod managers do not deploy this mod. Vortex and Mod Organizer deploy into one fixed folder inside a game, and this mod has to replace a file the game ships in its own bin folder, which no manager can do or roll back. Use the installer.

Success looks like: bin\tobii_gameintegration_x64.dll.backup appears next to bin\FarCry6.exe, and after launching the game once, bin\FarCry6HeadTracking.log opens with a line naming the head tracking API the game asked for.

The installer ZIP contains plugins\tobii_gameintegration_x64.dll.

1. Close the game.
2. In <Far Cry 6>\bin, rename tobii_gameintegration_x64.dll to tobii_gameintegration_x64.dll.backup.
3. Copy the mod's tobii_gameintegration_x64.dll into that folder.

Some installs also carry a bin_plus folder holding a second copy of the game binaries. The installer always deploys into bin. If the log never appears after a launch, repeat the two steps above in bin_plus as well.

1. Install OpenTrack.
2. Input: pick your tracker.
3. Output: UDP over network.
4. Open the output's settings and set the address to 127.0.0.1 and the port to 4242.
5. Press Start.

The mod listens on 4242 unless UdpPort in CameraUnlock.ini says otherwise. If something else on the PC already has that port, change it in both places.

1. Connect the headset to the PC over Air Link, Virtual Desktop or a link cable.
2. Start SteamVR.
3. Set OpenTrack's Input to the SteamVR tracker.
4. Leave Output on UDP over network, address 127.0.0.1, port 4242.

Set OpenTrack's Input to neuralnet tracker. It tracks your face from a plain webcam and needs no markers, no clip and no IR hardware. Leave the output as above.

A phone app is usable here only if it sends the OpenTrack UDP protocol itself, or ships a PC-side companion that does. Check your app against that first.

For an app that does send it, what decides the wiring is how much filtering the app does on the phone before the packet leaves it:

• Filters on-device: point the app straight at this PC's LAN address on port 4242. The mod listens on every interface, so the phone only needs the address and the port.
• Raw or lightly filtered: send it into OpenTrack on the PC as an input instead, and let OpenTrack's filters and curves clean the feed up before its UDP output goes to 127.0.0.1:4242. The mod's smoothing is sized to take the edge off a clean signal, not to rescue a noisy one.

The test is quicker than the reading: try direct, hold your head still, and if the view drifts or shakes, route it through OpenTrack instead.

I made Headcam so decent tracking was free for anybody with a phone already in their pocket. It filters on-device, so it can send direct.

A phone on WiFi is a remote connection and gets RemoteSmoothing. So does a tracker running on this same PC that sends to this machine's LAN address instead of 127.0.0.1, because the classifier reads the transport, not the machine.

Center in your tracker: OpenTrack's own Center bind, your phone app's center button, or SteamVR's view reset. The mod applies whatever pose the tracker sends.

Each action has a nav-cluster key and a Ctrl+Shift chord, so a keyboard without a nav cluster still reaches all of them:

The true free look chord is Ctrl+Shift+J in this game rather than the usual Ctrl+Shift+U, because Far Cry 6 opens the Arsenal on U, even with Ctrl and Shift held.

Page Up / Ctrl+Shift+G cycles tracking mode:

1. Normal head-tracked gameplay
2. Positional tracking disabled, rotational tracking enabled
3. Rotational tracking disabled, positional tracking enabled
4. Back to normal

Page Down switches yaw between the game's reference up axis (world) and the camera's up axis (local). The difference is visible when looking up or down with the mouse or controller, then turning your head.

The tracking mode, the yaw mode and true free look are saved to CameraUnlock.ini the moment you change them, so the game starts in the mode you left it in. End changes the current session only: the game starts with head tracking on or off as EnableOnStartup says.

Each hotkey is a list of keys in the [Hotkeys] section of the settings file, chords included, and every item in a list can be changed or removed: ToggleKey=End, Ctrl+Shift+Y.

Head tracking stays on while you aim. The weapon stays where your mouse or controller points it, so with your head turned it sits off to one side with its sights still lined up, and your rounds land where those sights point. Head movement is scaled to the zoom of iron sights, so aiming down them does not magnify it. Scopes have not been tested.

By default leaning never takes your eye off the sights, and leaning in towards them brings them closer, up to the rear sight. Insert / Ctrl+Shift+J switches to true free look: the weapon stays put and your head moves freely around it, so to see down the sights you have to put your head behind them, as you would in VR. It is hard, and it is off by default. The mod saves the mode you pick, so it holds the next time you start the game.

Leaning in and back carries on while the sights are up: the weapon stays where it is and your eye moves up to it or away from it. Leaning sideways or up and down eases out while the sights are up, because it would move your eye off them. In true free look it stays.

Your flashlight follows your head rather than your aim, and turns a little further than the view does. When you turn your head your eyes end up past the centre of the screen, so a beam matched to the view alone lands short of what you are looking at.

This setting is in the [Light] section of the settings file.

Settings live in bin\CameraUnlock.ini from this version on. FarCry6HeadTracking.ini, the file earlier versions used, is read once to fill it and is never changed.

The mod reads its settings when the game starts. Apart from creating the file then, it writes to it only when a hotkey changes the tracking mode, the yaw mode or true free look.

The mod reads its settings from bin\CameraUnlock.ini in the game folder, and creates the file when it starts and finds none. Edit it with any text editor.

A setting set to default takes its value from Defaults.ini, which every head tracking mod that keeps its settings in CameraUnlock.ini reads. Head tracking mods that keep their settings in another file do not read it. Writing a value in place of default changes that setting for this game only. When the mod saves a setting that a hotkey changed in game, it writes the new value in place of default, so that setting no longer follows Defaults.ini in this game until you set it to default again.

Defaults.ini is %AppData%\CameraUnlock\Defaults.ini on Windows; $XDG_CONFIG_HOME/CameraUnlock/Defaults.ini on Linux, or ~/.config/CameraUnlock/Defaults.ini where XDG_CONFIG_HOME is not set, under Wine and Proton too; and ~/Library/Application Support/CameraUnlock/Defaults.ini on macOS. The mod's log, where it writes one, names the file it read.

When the mod starts and finds no Defaults.ini, it creates one holding the built-in values, unless Windows runs the game as a packaged app. The mod never changes Defaults.ini after that. Edit it with any text editor.

The built-in value of each setting set to default below:

• UdpPort=4242
• EnableOnStartup=true
• WorldSpaceYaw=true
• RotationEnabled=true
• LocalSmoothing=0.0
• RemoteSmoothing=0.15
• PositionEnabled=true
• TrueFreeLook=false
• PositionLimitX=0.3
• PositionLimitY=0.2
• PositionLimitYDown=0.2
• PositionLimitZ=0.4
• PositionLimitZBack=0.1
• CollisionEnabled=true
• CollisionReleaseSmoothing=0.9
• ToggleKey=End, Ctrl+Shift+Y
• CycleTrackingModeKey=PageUp, Ctrl+Shift+G
• YawModeKey=PageDown, Ctrl+Shift+H
• LightMultiplier=1.5

With every setting at its default, the file reads:

; Far Cry 6 head tracking settings.
; Comments start with ; and go on their own line. Text after a value is part of the value.
; Hotkeys are key names such as End, PageUp or Ctrl+Shift+Y. Separate several with commas; leave empty for none.
; A setting set to default takes its value from Defaults.ini, which every head tracking mod
; that keeps its settings in CameraUnlock.ini reads: %AppData%\CameraUnlock\Defaults.ini on
; Windows, $XDG_CONFIG_HOME/CameraUnlock/Defaults.ini (normally ~/.config/CameraUnlock) on
; Linux, under Wine and Proton too, and ~/Library/Application Support/CameraUnlock/Defaults.ini
; on macOS. The log names the file it read. Change a setting in Defaults.ini to change it in
; every game that has it set to default, or write a value here instead of default to change it
; for this game only.

Read <Far Cry 6>\bin\FarCry6HeadTracking.log first. It always records the port, the settings that were loaded, whether packets are arriving, and a heartbeat line every 600 frames carrying the pose being handed to the game.

The mod is not loading: nothing in the log, or no log at all

• The mod is not in the folder the game launches from. Check that <Far Cry 6>\bin\tobii_gameintegration_x64.dll.backup exists; if it does not, the installer did not run against this copy of the game.
• If your install has a bin_plus folder, put the mod there too (see Manual Installation).

No tracking response: the log says the receiver is listening but nothing moves

• The heartbeat line shows listening=1 receiving=0: the mod has the port but no packets are arriving. Check the tracker is sending to port 4242 and to this machine.
• The heartbeat shows a moving pose but the view is still: eye tracking is off in the game. Turn on eye tracking and Extended View in the game's own settings. The game stores those two as EyeTrackingEnabled and EyeTrackingExtendedViewEnabled in its gamerprofile.xml, so you can check there which one is off.

No tracking response: the heartbeat shows listening=0

• Something else on this PC has port 4242. The usual cause is another game with a head tracking mod still running. The log line above the heartbeat carries what the OS said, for example bind failed with error 10048.
• Close the other program. The mod checks the port twice a second and picks it up within about a second of it coming free, so there is no need to restart Far Cry 6. The log says Bound UDP port 4242 ... tracking is live when it does.
• If nothing is holding the port, read the error the log quotes. Error 10013 means Windows has that port reserved (Hyper-V and WSL each reserve blocks of the high range); pick a different UdpPort in CameraUnlock.ini.

Jittery or unstable tracking

• Raise RemoteSmoothing for a phone or network tracker. Leave LocalSmoothing at 0 for a wired tracker on this PC.
• If your phone app sends a raw feed, route it through OpenTrack rather than sending direct (see Phone App Setup).

The view moves the wrong way on an axis

• Invert that axis in your tracker, and report it: the mod's own signs are meant to be right for every tracker, and it has no inversion setting of its own.

The view holds still in menus, the map and cutscenes

• By design. Far Cry 6 only applies the head pose during gameplay.

The view holds still in co-op

• By design. Set DisableInCoop=false if you want head tracking there too.
• The log records Multiplayer session published: N of 2 players whenever that changes. Far Cry 6 publishes a joinable session in single player too, so 1 of 2 is normal and leaves head tracking running.

The weapon is off to one side when I aim down sights

• Your head is turned: the weapon stays on your aim and you are looking past it. Turn back to it, or move your aim to where you are looking.

I can't see down the sights, they are misaligned

• You are in true free look and your head is leaned off them. Move your head back behind them, or press Insert / Ctrl+Shift+J to return to sights locked.

The game window moved when I launched

• By design, and only when you play windowed: once the game has finished placing its window, the mod centers it on the work area of the monitor it opened on. A window that is already centered, and a fullscreen or borderless one, are left where they are. There is no setting for this.

• The mod validates the game's camera interfaces before starting. It can find relocated functions and globals when their instruction and layout contracts still match. An ambiguous or changed contract disables tracking, with the reason and game fingerprint recorded in the log. A future patch may still require a mod update.
• Lean is limited by nearby geometry. The mod uses the game's collision query to keep the eye back from an obstruction. CollisionEnabled=false in CameraUnlock.ini turns this off, and CollisionReleaseSmoothing sets how gently the view eases back out once the wall is gone.
• The mod replaces a file the game ships. A game update, or verifying the files in Steam or Ubisoft Connect, restores the original. Run the installer again.
• A real Tobii eye tracker will not work while the mod is installed, because the mod takes the place of the library that talks to it.

Download the new release and run install.cmd again. Your settings files are kept.

Run uninstall.cmd. It restores the original library from the .backup beside it and removes the mod's log. bin\CameraUnlock.ini and bin\FarCry6HeadTracking.ini are kept, so your settings are still there if you install again, and Defaults.ini is not touched. There is no separate mod loader to take away, so uninstall.cmd /force is accepted but has nothing extra to remove here.

If you copied the mod into bin_plus by hand, undo that by hand as well: rename tobii_gameintegration_x64.dll.backup back over the mod. The uninstaller only touches the folder the installer used.

Needs CMake and Visual Studio 2022 or newer. The build never touches the game, there is nothing to reference from it.
