Getting Started

First steps

Open the window, find your way around its pages and learn how saving works.

Open and close the window

Press Control plus Shift plus M to open the Sightline window, and again to close it. You can also close it with the × in its title bar. To use another shortcut, see Hotkey and settings.

While the window is open:

Your mouse and keyboard go to Sightline. The camera does not turn and the truck does not react to keys.
Your wheel, pedals and controllers stay with the game. Sightline never touches them.
The game keeps running, so you see every change as you make it.

The window remembers where you left it, its size and the page you were on.

The pages

The menu on the left opens one page at a time:

Page	What it is for
Layout	One tab per view, with all its settings. + adds a view.
Start from...	The game's templates and the panorama builder
HUD	Where the HUD and menus are drawn
Profiles	Save and load named layouts
Backups	Copies of your file from before each Save
Settings	The hotkey, the outlines on the screen, Eyefinity and Surround

Hover over the name of any setting to read what it does. The small diamond at the end of the name means there is help to read.

Working with values

Drag a field left or right. While you drag, the mouse pointer is hidden and stays put, so you can keep going past the edge of the screen. It comes back where it was when you let go.
Double-click a field, or Ctrl + click it, to type an exact value. Press Enter to apply.
A reset button (a circular arrow) appears at the end of a field you have changed. Click it to put that one value back, either as it is saved in your file or to its default. Hover over it to see which value it goes back to.

Changes are live, saving is not

Every change is applied to the game immediately, but your multimon_config.sii file is not changed. While something differs from the file, the bottom of the window shows ● Unsaved and the Save button turns cyan.

The buttons at the top of every page:

Button	What it does
Undo, Redo	Step back and forward through your changes. Also Control plus Z, and Control plus Y or Control plus Shift plus Z.
...	Revert to the saved file throws away your live changes. Read again from the game picks up changes you made in the game's console.
Save	Writes the current layout to `multimon_config.sii`. A copy of the old file is kept first.

Where Sightline keeps its files

Everything Sightline writes lives in one folder inside the game's documents folder:

Folder

Documents/
└── American Truck Simulator/
    ├── multimon_config.sii
    └── .sightline/
        ├── profiles/
        ├── backups/
        ├── settings.ini
        └── sightline.log

Only the window's position is kept elsewhere, in sightline.ini next to the plugin. There is nothing to edit in it.

The only file outside these that Sightline changes is multimon_config.sii, and only when you press Save or restore a backup.
