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"

Crash when open level

When I try to open the second level of my game, it crashes on packed game. It works fine when playing in editor.

The log file has this error:

[2017.03.16-00.32.08:509][321]LogWindows:Error: Assertion failed: LocalExportIndex.IsNull() [File:D:\Build\++UE4+Release-4.15+Compile\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading.cpp] [Line: 1915]

Opening the file AsyncLoading at line 1915, the assert has this comment: "otherwise we have two exports that match and our criteria is not good enough". I have no idea what it means, but perhaps someone can explain it to me?

Fixed.

The issue happened because I had an actor on my level with a component marked with the "IsEditorOnly" flag.

Hi Marcio Daniel,

I believe you're running into the following crash, at least based on the error message you've provided:

https://issues.unrealengine.com/issue/UE-42492

Could you do me a favor and take a look at that and verify if that's the same issue (check the callstack as well).

If not, let me know and I'll be glad to continue to investigate.

Have a great day

I don't think so, Sean. I'm not even using the Leap Motion plugin.

Unfortunately, I didn't have the callstack. Look at my log (see attachment): link text

If there is a way to enable symbols or anything like that to see the callstack, please tell me.

Interesting, the error messages are similar so figured it was worth mentioning. Unfortunately the callstack in your log doesn't provide anything that we can go off of.

Is it a shipping build that's crashing for you or a development/debug build?

The build configuration doesn't matter, the issue happen on development/debug/shipping configurations.

But I found a checkbox named "Include Debug Files", so I now have the call stack: link text

(Why is this answer marked as "accepted"? If I did that, it was unintentionally. Is it possible to remove this flag?) (edit: forget about it, it's not marked anymore... weird)

Thank you for the help, Sean. I found the solution, it was an "IsEditorOnly" flag that was marked on a component in my level.
