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"

After looking at the output log, it appears that there are several errors related to warnings in your blueprints. If you'd like to provide the project, I can take a look at it and see if there is anything that stands out that could help resolve these errors.

You can zip up the project, upload it to Dropbox, and provide me with a link to download it. You can PM me the link on the forums: https://forums.unrealengine.com/member.php?160394-Sean-Flint

Hello,

After looking into your project, it appears that there are several blueprints that are failing to compile, which is causing your build to fail. What you'll need to do is go through and resolve all warnings and compiler errors in your blueprints (which you can find by looking at the output log) and then you should be able to build successfully.

Have a great day
