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"

Screen flickering blue on iOS phones

Working on a 2D card game in Unreal for iOS. When the game is launched on iOS the screen flashes blue only for the game map. The screen doesn't flash blue in Unreal or in mobile view but only on iOS.

This wasn't a problem in earlier iOS devices. (Currently using iOS 12.2)

Not sure why this is happening, Don't know if it is our code since the problem doesn't appear in the editor.

Thanks!

Product Version: UE 4.21

Check your post-process setting. We had one problem with Auto-Exposure being set to "Auto-Exposure basic" and got huge flickering in 4.22. But really try disabling screen effects, light effects etc. It is not much but usually it is one setting that causes such screen space glitches
