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"

Editor crash at launch 4.12.5 with OVRServer_64 running

When I launch 4.12.5 I immediately get a crash (doesn't get beyond 0%) if the OVRServer_64.exe process is running in the background. Crash doesn't happen on 4.11.2 or 4.13.2. Tested on windows 7 and windows 10.

Crash report:
