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"

RunUAT.bat ERROR: AutomationTool was unable to run successfully.

I know this a common issue, but I've tried the other options and nothing seems to work. Could someone please help me here, i can still package other projects, but i still occasionally run into this problem. I'm not a coder, and don't have visual studio or source access, just running standard UE4.

Hello, Dark_Jubei

I am sorry to hear about your issue.

It looks like the error has been caused by an extremely large map:

[2015.09.01-08.31.51:780][732]MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Source\Runtime\Core\Public\Serialization\Archive.h] [Line: 96]

[2015.09.01-08.31.51:781][732]MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: FMemoryWriter does not support data larger than 2GB. Archive name: K:/01. PROJECTS/Paragon/Unreal Project FIles/World_Vision_VRTest1/Content/WorldViewTest.umap.

Thus, please consider breaking the map into smaller pieces.

Hope this helped!

Good luck!

Hey Andrew, that was deffo one of the problems, i had a 7k 360 panoramic render in there, i was testing with but forgot about. Thanks a bunch for the help, i also had a strange issue where the engine would start generating invisible null objects everytime i tried to build. I deleted the object i think that was causing the issue, that also helped.

But thanks again, saved me a lot of trouble. Out of interest, is 4k a good resolution to try not to exceed? Just to avoid a similar problem in the future.
