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"

UE4 Not Recognizing Vive

Hi there,

I've been having some difficulty getting UE4 to recognize the Vive and allow for the VR preview option to be used. Yesterday, I was able to get it working for a bit after using the "HMD Enable" command, but then later it went back to not working randomly. The VR preview button is greyed out and none of the VR console commands are recognized. Otherwise, the Vive is functioning properly within Steam and its applications. I have checked and the SteamVR plugin is enabled within my project, so that shouldn't be the issue. I'm using UE4 version 4.9.1. Does anyone have any insight as to what might be going wrong?

Thanks in advance!

Product Version: UE 4.9
