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"

UE 4.21 iOS Screen blackout glitch

We have recently upgraded out project from 4.19 to 4.21 and have been experiencing screen blackouts in a distribution / development builds for iOS. When looking in certain directions in some levels now; the entire screen will go black with only the on screen widgets still displaying. Everything still runs fine, and when i turn the camera away the game returns to normal rendering.


Here is a short clip showing the error when i look at an object in a certain direction. I demonstrate before activating this object, i can look at it normally, but after chaining the material in game, my screen will go black when looking at the object in a specific direction. Both materials are almost identical in the editor, and there's nothing that stands out to me as to why this error is happening.

Has anyone else been having this issue since upgrading to the latest engine version ???

Product Version: UE 4.21
