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"

4.18 Enable apex destruction plugin failed to package

My project can be packaged successfully in 4.17 & 4.16. However, after enabling apex destruction plugin in 4.18.1, it has packaging issues. It runs totally fine in Editor, both new window and standalone. I'm building from source on Linux Ubuntu 16.04 using release branch of 4.18.1. Since my project requires destructible to be used, naturally I would turn on apex destruction plugin. Two critical issues came up (even with newly created empty c++ project):

(1) When packaging, it always shows failed to package due to "Unknown Cook Failure" no matter what packing configuration was set.

   LogInit: Display:
   1101LogInit: Display: Success - 0 error(s), 4 warning(s)
   LogInit: Display:
   Execution of commandlet took:  19.19 seconds
   Signal 11 caught.
 Took 33.547256s to run UE4Editor, ExitCode=139
 Cook failed. Deleting cooked data.
 ERROR: Cook failed.
        (see /home/it/Library/Logs/Unreal Engine/LocalBuildLogs/UAT_Log.txt for full exception trace)
 AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

 [2017.11.17-07.04.59:279][ 61]PackagingResults: Error: Unknown Cook Failure

(2) When normally exiting editor, 100% crash with the following backtrace stack

 [2017.11.17-06.39.51:744][394]LogInit: Tearing down SDL.
 *** Error in `/home/it/UnrealEngine/Engine/Binaries/Linux/UE4Editor': double free or corruption (!prev): 0x0000000003c5f4b0 ***
 ======= Backtrace: =========

Disabling the plugin avoids these two issues, but the destructible feature was totally gone. Any help would be appreciated.

Product Version: UE 4.18

Got similiar crash log and same linux signal in 4.18, remove the apex destruction plugin reference works for me. ps: every commandlet will crash when it's finished.

This issue should be fixed in 4.19 and is due to symbol collisions from a statically linked apex library. If you need to fix it in 4.18 you can cherry-pick this commit:
