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"

Unrecognized tab in child blueprints

I'm pretty sure this is a bug, please do correct me if i am wrong.

On opening any of the child blueprints (pictured) of BP_Master Item i get a pop up saying "unrecognized tab"

Recompiling the master blueprint seems to fix the issue for a while then it starts doing it again for unknown reasons.

it doesn't appear to be having an effect on the system, Its more of an annoyance than something which is holding back the project. Just thought you ought to know :).


sometimes there is a single tab that says "unrecognized tab" sometimes there are two, this appears to be random.

BP_MasterItem is just a BP actor for which i have replaced the default scene root with a scene and added a single variable which is a reference to a Struct holding item info.

the error seemed to appear after i had built my child blueprints the added a variable within the struct.

Let me know if i can offer any other information.

Seeing this as well with 4.17.1, don't believe it was happening with 4.17.0
