Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

PackagingResults:Error: Error Unknown Cook Failure

I'm getting an error when packing my project.

UAT_Log link text

I open the project and Output Log show this error.

Any ideas why this might be happening or what I can do to fix it?

Syaoran,

Have you tried deleting your Intermediate and Saved folder from your project? If not, please attempt that and try to package again. If that doe snot work, I would suggest also trying to re-verify your version of the engine if it's a binary version. If it's a source version of the engine, you may want to delete the Classes folder inside of Engine\Source\Runtime\Engine and rebuild the engine to replace the files deleted as they could be corrupted.

Once you've done that, please try to package again. Please also try to package a blank project to see if it's simply the project you're working on or packaging in general. Upload new error output logs for review once you've gotten through all of these suggestions.

Thanks!

Since blank projects are building successfully, it comes down to something in your project causing this error to occur.

  • Have you changed any of the Project Settings or set a blueprint up in a way that you hadn't before?

  • Have you tried migrating your project files over from 4.13 to 4.14?

Migrating is found in the content browser by right-clicking on the files and selecting 'migrate'.

Hi:

I find the LogOutputDevice:Error: Trying to reference an unowned pin: B9F5DD9545A8DB10B1746382716ECE12

It cause from my BP_MacroLibrary, but I don't known why...

But I change spawn actor from class to my BP_character. So I can packaging my project now.

1 .Project Settings I only change default map and some rendering setting.

2 .I tried migrating my project files over from 4.13 to 4.14, but when I click any file then editor crash.

When you originally had this blueprint, was it created in an older version of the engine and then upgraded to a newer version of the engine? If so, which versions of the engines did you start in and move to?

The BP_MacroLibrary_Common blueprint add at 9/1, so I think the engines version is 4.12.5.

The SpawnProjectile_ForAI macro add at 10/11, so I think the engines version is 4.13.1.

The SBasePickup blueprint(Duclicate from VR template BP_PickupCube) add at 9/8 so I think the engines version is 4.13.0.

The UFOPick blueprint(Parent class "SBasePickup") add at 9/20 so I think the engines version is 4.13.0.

The UFOPick_ForAttack blueprint(Parent class "UFOPick") add at 11/7, so I think the engines version is 4.13.2.

Since UFOPick_ForAttack_C and SBasePickup_C are the blueprints throwing errors, those are the ones that I would begin to recreate with new nodes. I would probably recreate BP_MacroLibrary too.
