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"

Hey BinaryWaves-

The error message states an "illegal instruction" was the issue, can you tell me what command you ran when this crash occurred? If this occurred when running the editor with ./UE4Editor from the terminal, can you specifically run make UE4Editor from the location where you ran ./Setup.sh and ./GenerateProjectFiles.sh? If you still get a crash as this, please provide as much information about exactly what you're doing and where the crash is occurring.
