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"

Unreal Engine 4.7: Assertion failed: Det != 0.0f

Hello,

I try to port an existing game to 4.7 and get a crash in the editor as soon as I open a user interface. I think it might have to do something with zooming in or out. The error is:

 2015.01.26-07.54.40:648][511]LogContentBrowser:Verbose: The content browser source was changed by the sources view to '/Game/MMO/Blueprints/UserInterface'

Does somebody have an idea what this could be? Opening the very same interface under 4.6.1 works.

Regards,

Heiko
