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"

How to apply changes in scene back to the original blueprint

As the Title. How can I apply the changes I made in an instance of a blueprint to the original one.

I got a blueprint. It extends my c++ class A;

UFUNCTION(CallInEditor) A::DoSomePrecalculationsAndStoreThemInMyself() ;

Dragged this blueprint into scene and executed this function, the data I need is propperly assigned.

Ok.......... I found no way to save the data back to the original blueprint............

==============================================================================

So my question is "Is there a way to change blueprint like 'Apply changes to a prefab' in Unity ?"
