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"

Unable to launch on android 7.0

Trying to delploy to my LG Sytlo 2 and it gets an error "Error Launch Failed!! Unkown Error". I say some post about he C++ Toolchain not installed but I do not have such an error in the log. The only other error lines I see are

"ERROR: UBT ERROR: Failed to produce item: D:\Development\Unreal Projects\MyProject2\Binaries\Android\MyProject2-armv7-es2.so"


"Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.CommandUtils+CommandFailedException: Command failed (Result:5): F:\ProgramFiles (x86)\Epic Games\UE_4.16\Engine\Binaries\DotNET\UnrealBuildTool.exe MyProject2 Android Development -Project="D:\Development\Unreal Projects\MyProject2\MyProject2.uproject" "D:\Development \Unreal Projects\MyProject2\MyProject2.uproject" -NoUBTMakefiles -remoteini="D:\Development\Unreal Projects\MyProject2" -noxge -NoHotReload -ignorejunk. See logfile for details: 'UnrealBuildTool-2017.06.24-13.31.52.txt'"'

I do not know where the UnrealBuildTool-2017.06.24-13.31.52.txt log file is located. Full log output is attached.

error: no viable conversion from 'uint8' (aka 'unsigned char') to 'FVector'


Check out this Source File, it seems you are trying to convert an uint8 to FVector.

You're a champ thanks. I wish their debug was more user friendly. Where can I find the UnrealBuildTool log it speaks of?

It's sadly not in your Project folder and you can search for UnrealBuilldTool on your harddrives.

However, the default location is C:\Users\YourUserName\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+EpicGames+UE_4.16
