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"

Level Data New Var

Whenever I start the unreal engine 4 project, the above pops in. It doesn't matter I select OK or Cancel. It keeps appearing every time I start the project. Is there a way I can debug or fix this ?

Thanks for your time.

Hi gameme,

Make sure that these two variables are deleted and all references to them are removed in any blueprints. If you still get this error after that, post back and let us know.

I had the same problem in 4.19. The solution that helped me: go to the C:/Users/Your_user_name/AppData/Local/UnrelEngine/4.19(or your engine version) and delete everything there. After that the project launched without any error.

I hope it will help anybody who face the same problem
