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"

Build debug not enough BP info

Migrated to 4.21. There are build errors for packaging Win64. Problem is the log messages are never specific enough no matter where I look.

I will get messages preceding with:

UATHelper: Packaging (Windows (64-bit)): LogStreamableManager: Error:

or errors about nodes not calculating through source.

But it never tells me which Blueprints, nodes or source files are failing. There's no reference info provided so it makes debugging nearly impossible.

Product Version: UE 4.21

I did not create it. Problem is finding it is difficult because it doesn't say where it's coming from.

is error happens when no plugins active?

avatar image MikeRPG Feb 16 '19 at 05:20 PM

Yes it happens with plugins deactivated

hmm. are you tried to "fix files"? (when you click on asset there's that function)
