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"

Can't execute package - Assertion failed


I'm having an issue when I try to execute a package I've been working on for some time now. I'm using the multi-user viewer template with my HTC Vive and everytime I try to Host a Session, I get this message:

Assertion Failed: !SteamVRHMD -> VRCompositor [File:D:\Build\++UE4\Sync\Engine\Plugins\Runtime\Steam\SteamVR\Source\SteamVR\Private\SteamVRSplash.cpp] [Line:54]

Does anyone know how I could fix this problem and finally run my project?

Also, if I try to run it in Desktop mode instead of VR mode, it works fine.

Thank you in advance.

Product Version: UE 4.22
