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"

UE4 hangs randomly - DerivedDataCache & adb.exe

Hi

After some "random" time, even if I leave the unreal engine idle it hangs. It does so without any OS hang or crash messages. It only uses 100% of one core (25% cpu usage in my quad core case).

What I found out is that the UE4Editor-Cmd looks into C:/programData/Epic/Engine/DerivedDataCache folders.

To "fix" this, or rather unlocking the engine from this nasty loop, I only had to rename DerivedDataCache to something else. Of course I recommend renaming it back after it.

Edit: Don't know if this is related, sometimes it still hangs similarly and it gets stuck with adb :/ One solution there, is to restart adb so that the daemon reactivates, then UE4 will resume from hang.
