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"

Every time I compile, random BP data gets reset

Since upgrading to 4.18, I have been experiencing the following issue: every time I compile my C++ code, random UPROPERTY(EditDefaultsOnly) variables in my BluePrint classes get reset to their default values. The BluePrints that get reset aren't necessarily based on classes I edited before compiling. This happens nearly every time I compile. I didn't experience this in 4.17, 4.16, or 4.15.

Is anyone else experiencing this?

Product Version: UE 4.18

Yes, I am experiencing this in Unreal 4.20.1., too. Hopefully this will get fixed, soon!

This is a HotReload bug. It happens when you change the header file for an object and HotReload compile.

After you've recompiled with hot reload you can exit the editor and re-launch it. This will prevent HotReload from resetting your BP values.
