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"

Editor sometimes crash when closing.

This is by no means a huge blocker, but sometimes, the editor crashes when closing it and it's always with the same stack :

      UE4Editor.exe!WinMain(HINSTANCE__ * hInInstance, HINSTANCE__ * hPrevInstance, char * __formal, int nCmdShow) Line 202    C++

I'm on version 4.7.1 of the engine, slightly modified for our use, but nothing in relation to rendering or nothing really "deep". I was wondering if someone else has the same issue or maybe if that is a known bug that is going to be fixed or was fixed in the new releases. Or maybe this is a symptom of something we are doing wrong with our game?

Hi Michael,

Please attach the log from this project after you get this crash. You can find this in the \Saved\Logs folder in your project folder. If you could also copy/paste the text from the Crash Reporter window when it comes up, it'll help us find the crash report. Thanks!

And just to be sure I understand, this only happens occasionally, and it happens when you close the editor?

We have a similar crash we're already looking into (UE-11611), and I'd like to see if this is related. Do you have an Oculus plugged in when it crashes?

The log pretty much is the stack I sent earlier. And yes, I have an Oculus DK2 plugged in, the game we are developing is VR centric.

Hey Michael,

Thanks! I can confirm that this is the same bug we already have logged (UE-11611), and I've included your information in the bug report. I'll let you know if I see any update on the report, or if the developers have any additional questions for you as they look into fixing it. For now, we have confirmed that this does not occur without the Oculus, so you might try unplugging it before closing the editor. Thanks for your report!
