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 Snowl0l-

There are some known issues with Visual Studio Update 3 and the engine. You can read more information about this here: https://answers.unrealengine.com/questions/435600/build-failed-with-vs-2015-update-3.html - We do hope to include support for Update 3 in a future update to the engine, however for now it would be best to revert back to Update 2.

Is there a way to revert back to update 2?

Hey Everyone,

Following the directions in the post by Infected_Post here allowed me to uninstall/reinstall VS2015 Community without Update 3. It does not appear to include a means of obtaining Update 1 or 2, but you should be able to continue using your code projects.
