WAR THUNDER

Install custom sights

A custom sight is a set of reticle element settings in a .blk file. It is not an image: this configuration file controls the sight's look and behavior in game.

Step-by-step guide

Find UserSights

Open the War Thunder save folder for your profile. Current paths:

Windows: C:\Users\username\Documents\My Games\WarThunder\Saves\GameID\production\UserSights
Linux: HOME/.config/WarThunder/Saves/GameID/production/UserSights
Mac: Users/username/My Games/WarThunder/Saves/GameID/production/UserSights

Replace GameID with your profile ID. If UserSights is missing, create the folder manually.

Identify the vehicle

Check which ground vehicle the sight is intended for. For one vehicle, create a folder with that vehicle ID inside UserSights. If it supports several vehicles, use all_tanks.

Place the .blk

Copy the sight file into the correct folder:

...\production\UserSights\<vehicle ID>\Astolfo.blk
or
...\production\UserSights\all_tanks\Astolfo.blk

Restart the client

Restart the War Thunder client. In the hangar, select a ground vehicle.

Select the sight

Open Game Settings → Main Parameters → Ground Battle Settings → Sight Settings. In Reticle, select the custom sight and press Save.

If the sight is missing

Check GameID, the exact UserSights name, vehicle folder and .blk extension, not .blk.txt. The file must not be one level too high or too deep. Restart the client after correcting it.

Verify an edited BLK

In a test drive, Alt+F9 reloads an edited sight file. Check text, circles, brush thickness, hatch gaps and fill holes. The editor canvas does not prove in-game rendering.
