Hello there @user_e4af5306dc3668d4fabcf41c383ef7b774d656501864a7c1c2dd94!

No worries, logs can be a daunting task, thank you for sending the extract. The log shows that the cooking process failed, but the specific reason isn’t clear. The first basic step to help the project would be to clear its cache.

To do that, please close UE, navigate to your project’s directory, and delete the following folders:

  • Saved
  • DerivedDataCache
  • Binaries
  • Intermediate

After that, restart UE, and let it rebuild the files, then test cooking again. If the issue persists, then we will need to check the extended cook log, which should be available here:

D:\EPIC\UE_5.32\UE_5.3\Engine\Programs\AutomationTool\Saved\Cook-2025.07.11-06.26.48.txt
