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"

Details tab in BP editor crashes UE4 randomly


I work in UE4 on a few machines and one of this computers have random problems with Details tab in BP editor. Just hovering a cursor above the tab can cause the crash. The same happens sometimes when opening BP class without nodes and only details covering the whole window.

  • Windows 8.1 Pro, 64-bit

  • AMD Phenom II X4 980, 3.73 GHz

  • 8 GB of RAM

  • Nvidia GeForce GTX 550 Ti

Drivers were updated around one month ago, but the issue is even older.

Hi Ed,

Thank you for quick info and workaround. I see steps to reproduce are still unclear, so when I find out something more, should I post it here, or in that other topic?
