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"

Startup Movies and Loading Screens are interrupted if a streaming level is set to Initially Loaded

When playing a StartupMovie, the flag "Wait For Movies To Complete" has no effect if the level being loaded has one or more streaming levels set to initially loaded.

Similarly, when using a LoadingScreen, bAutoCompleteWhenLoadingCompletes and MinimumLoadingScreenDisplayTime will have no effect when one or more initially loaded streaming levels is present.

I believe this is the same issue reported here: https://answers.unrealengine.com/questions/432254/startup-movies-dont-run-if-streaming-levels-are-en.html


  1. Create a new project

  2. Add a StartupMovie (using ProjectSettings | Movies | StartupMovies). You can use the TestVideo provided by Tim Hobson here : https://forums.unrealengine.com/showthread.php?100102-Startup-movie-help

  3. Set "Wait For Movies to Complete" to checked

  4. At this point, package the project and run the exe to show that the movie completes before the game starts.

  5. Add a new level via the Levels panel

  6. Open the Level Details for the new level and set "Initially Loaded" and "Initially Visible" to true

  7. Package the project again, run the exe, and note that the movie is now interrupted and the game starts almost immediately

As noted above, the same effect occurs for LoadingScreens. I set them up following this guide: https://wiki.unrealengine.com/Loading_Screen. With streaming levels initially loaded, the loading screen will not wait for completion or for the specified duration.

Thanks, -Kelson

Hi KGist,

I was able to reproduce this on my end and have entered a bug report, UE-33576, to be assessed by the development staff.

I had this same issue because I was calling on load streaming level even if it was unchecked to show once loaded. I stopped it by changing to load level on a action of pushing the button of start game.
