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"

[4.17] ChildActor Component does't allow to click and edit spline


I'm trying to create an actor with inside a childactor component, the class I use for the childactor is a simple actor class which holds a spline component inside.

The problem is that when I select the spline actor class as my child actor class for the childactor component I cannot select the spline anymore and obviously I cannot edit the spline points. The latter occurs both in the blueprint editor viewport as well as in the engine viewport.

I have tested this on several engine's versions including 4.14, 4.15, 4.16 and 4.17.

To recreate the bug: - Create a new blank project (either C++ or blueprint) - Create a blueprint class based on actor and add a spline component - Create another blueprint class based on actor and add a childactor component - Select the childactor component and for the child actor class select the blueprint created which holds the spline component - Try to click on the spline, and it will disappear

I saw others reporting similar issues with both the spline component, but the bugs are marked as fixed. I also saw others reporting about some issues with the child actor component, but those are also marked as fixed.

Thanks for your time.

We need this bugfix. Actually it is a huge limitation on the spline system!
