How To Install Custom Sights In War Thunder: A Comprehensive Technical Guide

Arbitrary values for tank sights - General Discussion - War Thunder ...

Installing custom sights in War Thunder allows players to bypass generic HUD limitations, enabling precise ballistic calculations and personalized visual overlays for specific tanks. By navigating the game’s local directory structure and modifying the UserSights configuration, users can implement high-fidelity reticles that drastically improve long-range accuracy and target acquisition efficiency.


Pre-Procedure Configuration and Directory Requirements

Before attempting to implement custom sight modifications, you must ensure your War Thunder installation is localized correctly on your primary drive. Custom sights are not downloaded via the game launcher; they are manually injected into the UserSights folder within the game’s root directory. Failure to correctly structure these folders will result in the game failing to recognize the custom files, leaving you with default optics.



  • Essential Software: A reliable file compression utility such as WinRAR, 7-Zip, or the standard Windows file explorer to extract .zip or .rar sight packages.
  • Directory Knowledge: Familiarity with the path structure, typically located at C:\Program Files (x86)\Steam\steamapps\common\War Thunder or your custom Gaijin installation path.
  • Mandatory Prerequisite: You must have launched the game at least once to ensure the UserSights folder is generated. If it does not exist, you must create it manually within the primary game directory.
  • Time Benchmark: The entire installation and validation process typically requires five to ten minutes of manual file manipulation.

Technical Implementation Workflow for Custom Reticles



Step 1: Locating and Preparing the UserSights Directory

Navigate to your primary War Thunder installation folder. If you installed the game via Steam, this is usually found in the common steamapps folder. Once inside, locate the folder labeled UserSights. If this folder is absent, right-click inside the main War Thunder folder, select New, then Folder, and name it UserSights exactly. This directory serves as the root container for all customized optical modifications.



Step 2: Downloading and Extracting Sight Data

Visit reputable community hubs such as War Thunder Live to select your desired sight package. Download the compressed file. Once the download is complete, extract the contents to a temporary location on your desktop. Ensure the extracted folder contains an .blk file and, in many cases, a subfolder containing the texture assets.



Step 3: Deployment to the Game Root

Move the extracted folder directly into the UserSights directory you verified in Step 1. The path should look like War Thunder/UserSights/[Name of your Tank]/[Files]. Do not place the files directly into the UserSights root folder if you have multiple sights; ensure they are organized by their respective vehicle identification strings to prevent conflicts.



Step 4: Activating Sights In-Game

Launch War Thunder and enter the Test Drive mode or a live match. Open the Options menu, navigate to the Main Parameters tab, and locate the Tank Battle Settings sub-menu. Look for the dropdown menu labeled Use Custom Sight. Select the name of the tank associated with your new sights. Once selected, press Alt + F9 while in the tank view to refresh the sight configuration if the changes do not manifest immediately.

Pro-Tip: If your sight appears offset or misaligned, check the .blk file within your sight folder. Some sights are designed for specific resolutions or aspect ratios; editing the 'rangefinder' and 'crosshair' lines within the .blk file using a standard text editor allows for minor manual calibration if the default positioning is slightly off-center.

Warning: Never modify the files within the game’s internal root folders other than the UserSights directory. Modifying core game files like .assets or .vromfs can trigger the Easy Anti-Cheat (EAC) system and may lead to account restrictions or forced file integrity verification which will wipe your custom modifications.

Common Field Failures and Technical Troubleshooting



  • Root Cause: Incorrect directory nesting. If the sight folder is buried too deep or not deep enough, the game engine ignores the files.

    • Actionable Fix: Ensure the directory structure is exactly UserSights/[TankName]/[Files]. Ensure there are no redundant nested folders between the tank name and the actual .blk file.
  • Root Cause: Cached game configuration. The game may still be loading the default configuration from its memory cache.

    • Actionable Fix: Use the keyboard shortcut Alt + F9 while in the vehicle in a test drive. This forces the game to reload all local user-defined sight configuration files without requiring a full restart.
  • Root Cause: File naming incompatibility. Some community-created sights utilize outdated file names that do not match current vehicle code names in the game files.

    • Actionable Fix: Open the .blk file in Notepad. Check the header section for the vehicle association string. If it differs from the current game version's technical name, rename the folder to match the updated vehicle ID exactly.

Frequently Asked Questions



Can custom sights result in an account ban?

Custom sights are officially permitted by Gaijin Entertainment. Because these files only modify the visual overlay of the tank optics and do not alter weapon performance, ballistic coefficients, or game logic, they do not violate the terms of service.



Do I need to re-install sights after a game update?

Most major updates that include changes to vehicle models or optical systems may break specific custom sights. If your sight disappears or stops rendering after a patch, check the original download page for an updated version or verify the folder structure remains unchanged.



Can I use the same sight for different tanks?

You can copy the .blk file from one tank folder to another within the UserSights directory, but you must rename the folder to match the specific vehicle ID of the new tank. Note that ballistics vary significantly between tanks, so a sight calibrated for a 120mm cannon will be inaccurate for a 75mm cannon.



Is there a way to preview sights before installing them?

Yes, use the Test Drive feature within War Thunder to observe the sight in action. If you have multiple sights installed for the same vehicle, you can toggle between them in the Tank Battle Settings menu while in the test range to see which best fits your preferred display style.

Optimize your combat performance by installing high-precision custom sights that match your specific vehicle's ballistic profile. Explore the War Thunder community repositories today to find the reticle configuration that best suits your tactical requirements.
