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"

Can't see new Native components in BPs when added in C++

Hey guys,

So I altered one of my C++ classes to include a native spring component and an attached native camera, but these won't show up in the Components tab. I had to make a whole new Blueprint, which means whenever I want to change my native components, I need to copy across all of my functions, event handling, defaults tab settings, etc. This has a huge impact on my workflow.

Is this a bug, and if so, is it already known / being worked on?


EDIT: This is also the case with BPs that inherit from a BP that itself inherits from the native class in which these changes are occurring. If I have a base class in C++ whose components I change, every single BP that inherits in some way from this (BP->Code or BP->BP->Code) have to be completely rebuilt to see the new components. That's a problem.

Try deleting your Saved and DerivedDataCache folder to force the BPs to be rebuilt.
