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"

Hi DeButcher,

Your callstack looks like the one from this report: https://issues.unrealengine.com/issue/UE-37999

Another issue that is very similar is this one: https://issues.unrealengine.com/issue/UE-38818

They are both pretty much the same and plan to be addressed in the same fix. This is actually our most reoccurring crash and we plan to address this asap. I know the fix version is listed as 4.15 but this will most certainly be addressed in a hotfix as having a known crash this major would be unacceptable in any version.

This crash is tied to the GPU and can't really be worked around until the patch is out. I would recommend using 4.13 for the time being.

Thanks,

Ed
