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 instance multiplayer — connection lost

When you try to load a level instance, the client is disconnected from the server. If you load instance from the server's rights, then the client does not disconnected, but the loaded instances are invisible.

Disconnection occurs when setting "should be visible" to true. The same thing happens on a new test project.

Link to the test project. The logic for loading the level is in Content\FirstPersonBP\Blueprints\FirstPersonCharacter

I have encountered the same issue, and dug into the code in order to find the cause. It appears the call to APlayerController::ServerUpdateLevelVisibility fails, as the client-provided PackageName cannot find a match in the UWorld's StreamingLevels array. More precisely, this array does contain an identical package name, but the Number fields of the FName objects are different, causing the equality test to return false.
