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"

Expanding node inside FlipFlop crashes UE4.6

Updated from 4.6 Preview to 4.6 yesterday; and tried out a blueprint with a FlipFlop.

Creating a FlipFlop, rightclicking and then clicking on Expand Node crashes the Engine.

I've tried with a 4.6 Preview project and a new blank one, both repro 100%.

Already submitted 3 of these bug reports.

I can't find any recent logs in C:\Program Files\Unreal Engine\4.6\Engine\Saved\Logs

Hi Moter8,

Thanks for the report! I was able to verify this in 4.5, 4.6, and our internal engine, and have entered a bug report in our system (UE-6234). It appears that the Expand Node option in the right-click menu is not functioning correctly for any composited node (For Loops, FlipFlop, etc). For now, you should still be able to double-click the node to open it up and look inside.

Hope that helps, and thanks again for bringing the issue to our attention!
