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 WadeeSami,

We'll need some more information in order to help you resolve this. When the Crash Reporter window is open please copy your machine ID and post here, then make sure you hit submit to be sure the crash data is sent to our crash reporter site. We are often able to link this to other users crashes to determine the cause.

In the meantime, you can try the following:

  1. Delete the Derived Data Cache folder from the install directory

  2. Delete the Intermediate, Saved and Config folders from the Project Folder. *keep a back up of your Config folder and, if you can restart the editor, you can likely add this back to restore your Project and Editor settings.

Let us know if these steps resolve the issue. If not send the requested information above.
