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"

I'm getting the same error.

Same error. And I can't even get it to play at all... So much frustration....

Tested the compile because my 4.8 project which I migrated to 4.9 no longer compiles either. I figured I'd try compiling the VR demo, and it failed, just like most people are reporting. Annoyingly with an unknown cook failure, which is very non-descript :(

if you read the full log file it tells you exactly where it failed. the summary is useless :/

When loading in 4.9 i found and error in /Game/Audio/Blueprints/Surrondpanner

in the event Graph: GetWorldRotation and GetTargetLocation were invalid and pointing at self

to fix I Replaced the two invalid function instances with a valid target "AudioCenter"

I cooked and played and audio tracked head movement properly.

The demo is working for me with 10.4. Did you try with the latest updates?
