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"

property can not be set in blueprint-defaults if it is from type AActor


I have added a property in a custom derived actor like this:

 UPROPERTY(Category=Rendering, EditAnywhere, BlueprintReadWrite)
 AActor* RelatedActor;

The property can be edited in every spawned instance if for example selected in the scene outliner and edited in the details panel. However, if I am trying to set an actor in the blueprint default panel, every selection is not being accepted.

The log outputs:

LogUObjectGlobals:Warning: Failed to find object LogProperty:Warning: Illegal TEXT reference to a private object in external package

Any clues ?

Looking for the answer too. Did not have this problem until 4.12.3.

I worked around this. I have sub levels. I locked the level where I had the InfiniteAffordableLandscapes Island. I put all the blueprint actors and static meshes, etc on another level.

Still getting complaints about externally referenced issues, but I can assign to the entry on the blueprint.

Your idea about sublevels is the answer for problem when you get "Warning: Illegal TEXT reference to a private object in external package...". So, blueprint instance and actor to be set as blueprint's Default should be in one level (Window -> levels)
