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"

Twitch live stream instantly crashes.

Can't get twitch streaming to work at all. Is this suppose to work? I'm on the latest. 4.7.6. I have the engine source code, so if there is a source code fix that is simple, post instructions. Wasn't this announced months ago?

Hey sgehrman,

From where are you attempting to launch the twitch stream?

Would you mind providing me with your crash logs, .dmp files, and full callstack generated from the crash in a zip file and attached to your response please.

Also, some reproducible steps in order for me to get this crash to occur on my side would be very helpful when it comes time to write a bug report.

Thank you,

Andrew Hurley

The editor button, or blueprints inside the game, both crash. Do I still need to get the SDK from Twitch and install it myself? This feature has been talked about for almost a year. Is it going to work soon?

Currently the Twitch plugin is in limbo as far as its complete integration in the Engine. I found this information on our Documentation page which will help answer some of the questions you have asked.

https://docs.unrealengine.com/latest/INT/Support/Builds/ReleaseNotes/2014/4_4/index.html

With this in mind, I am still going to enter a bug report for the crash. Let me know if you have any further questions or if you need additional assistance.

The bug report associate with your crash is now in our system as UE-15465.

Regards,

Andrew Hurley
