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: Unknown Cook Failure

I have packaged previous, smaller versions of my game in the past, and they have compiled without error. For some reason now, with two larger updates, the game is now completely unable to compile, giving me a "PackagingResults: Error: Unknown Cook Failure".

I noticed a few things in my output log: I use a lot of the starter content textures on my BSP's in the map, as well as on some models as temporary textures. Some of these textures seem to be creating errors when loading them: "UATHelper: Packaging (Windows (32-bit)): Cook: LogInit: Display: LogCook: Error: Error loading C:/Users/Cayden Berry/Documents/Unreal Projects/SOS/Content/Cooked/WindowsNoEditor/SOS/Content/StarterContent/Materials/M_Concrete_Tiles.uasset!" As well as M_Metal_Burnished_Steel.uasset, M_Metal_Chrome.uasset, M_Metal_Steel.uasset

I also seem to be getting warnings with "FBufferReader" because it is unversioned.

I also have this, I don't know if it helps or not: UATHelper: Packaging (Windows (32-bit)): Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Cook failed. ---> AutomationTool.CommandletException: BUILD FAILED: Failed while running Cook for C:\Users\Cayden Berry\Documents\Unreal Projects\SOS\SOS.uproject; see log C:\Users\Cayden Berry\AppData\Roaming\Unreal Eng ine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_4.17\Cook-2018.03.26-08.29.00.txt

Attached below is the file Cook-2018.03.26--08.29.00.txt, just in case if you wanted to see that. I do not know what to look for in terms of important errors, as there is no guide on it that I could find, and any content that I looked up regarding this didn't really help out my situation.
