How to resolve LowLevelFatalError in Unreal Engine?

Step-by-step guide to troubleshooting common causes of LowLevelFatalError

Encountering a Low Level Fatal Error in Unreal Engine can be frustrating. This guide provides step-by-step instructions to troubleshoot and potentially resolve this issue.

Steps to resolve Low Level Fatal Error:

  1. Update Graphics Drivers: Ensuring that your graphics drivers are up-to-date is crucial. Here’s how you can update them based on your hardware:

    • NVidia Users: Use the GeForce Experience application to check and update drivers.
    • AMD Users: Use AMD Radeon Software for driver updates.
    • Alternatively, visit NVidia's or AMD's official website to download the latest drivers.
  2. Use Unreal Engine's DirectX11 Startup Parameter: Sometimes, forcing Unreal Engine to start using DirectX11 can resolve compatibility issues. Here’s how to set it up:

    • Locate the shortcut for “Brightearth Antibes” on your desktop.
    • Right-click on the shortcut and select “Properties.”
    • In the “Shortcut” tab, find the “Target” field. Add " -d3d11" (including a space before the dash) at the end of the line. This should be added after the closing quotation mark of the target path.
