Hello guy’s, I need your help,

I’m now working with UE 4.16.1 for 4 weeks and I have created a new level which contains a lot of meshes and things. I’ve tried to export it to windows 64bit, but I keep seeing this Error Unknown Cook Failure. I’ve looked on earlier threads and they said i should rename my project and reboot my pc but this doesn’t work for me. I hope you can help me out with this!

For the attachment i put my error report inside,
If you need more I will be available.

Kind regard and I’m very great-full!

Leon Rook.

  1. Make a copy of your project for safety reasons
  2. Delete all subfolders from the project folder EXCEPT for Content, Config and Source (if any) and for the .uproject file. You should delete Build, Saved, Intermediate, etc.
  3. Open the project, rebuild all lights etc.
  4. Try to package and see if the error is gone
