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"

Lighting Needs to be rebuilt message after packaging

Hello everyone,

My team and I have run into a bit of a weird issue. All maps have been built correctly inside UE. We can run them no problem in editor. Once we try to 'Launch' or 'Package' and load the main level from the Title Menu, however, we start getting: "Lighting needs to be rebuilt"

We're not sure why. Any idea where to even start with debugging this? Building is successful. Packaging is successful. The two scenes use different game modes however: Third Person Game Mode for Main Level and a custom Game Mode for the Title Screen (which has our HUD and no spawn).

All help appreciated. Thank you so much

Product Version: UE 4.19
