The error message “Module Validation Failed” occurs every time I launch the game or try calculating the memory in Unreal Editor for Fortnite (UEFN). It indicates that the system is unable to download the necessary source assets for the job, preventing the successful creation of the module version. This issue might stem from missing or corrupt assets, network connection problems, or incorrect project configurations.

If you’ve deleted stuff and references could be stuck in the HLOD layer try this

This is how I replace HLOD Layer (pasted from a text file)

  • Close Fortnite Edit/Play Mode
  • Check-in Changes and make a snapshot with URC
  • Make a new HLOD Layer in Content Browser - Right Click>World>HLOD Layer
  • Delete existing HLOD Layer - Replace References to the new one -
  • DON’T Save When it asks, otherwise it will possibly keep bad references in there
  • Double Click on Level Thumbnail
  • Now you can Save if prompted.
  • Then do a Build Landscape - ignore Yellow Warnings - use drop the down filter to deselect them - deal with Red Errors
  • Double Click your Level Thumbnail again, Save if prompted
  • Build HLODs
  • Try to launch session
