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"

Memory leak

Create a new thread as asked here: https://answers.unrealengine.com/questions/334146/410-memory-leak.html

Memory leak was caused by a widget component inside a blueprint. Memory leak starts when blueprint placed in the level, or just opened in a new tab\window(Loaded into memory basically)

For test purposes I test it on 4.9, and 4.10. Both versions get the same results.

Repro steps:

  1. Any project will do but you can create a new one.

  2. Create a new UMG.

  3. Place a Text(Not TextBox, I did not test it with TextBox)

  4. And change Text to " "(Not empty, a single space character)

  5. Then Create Blueprint.

  6. Add Widget component to it.

  7. Set widget class to our previously created widget(with " " text).

  8. Place it anywhere in the level, memory leak should start any moment(Usually 10-60 secs).

I hope you will get the same result, it was really annoying bug.

Product Version: UE 4.10
