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"

Unreal 4.12 won't open in Oculus Rift CV1

Have a project that was opening in Oculus fine with 4.11.2 (via Alt-Enter after launching), but now after upgrading to 4.12 it's no longer working. VR Preview still works within editor-- just not the build. Any ideas? Thanks.

Product Version: UE 4.12

no vr preview was not greyed out. Not sure what the status is of Unreal with DK2. My CV1 is now working fine with 4.13-- there's also a great new VR template: http://www.tomlooman.com/vrtemplate/

You can get it to work by executing with -vr, or typing "stereo on" into the console while playing.

Performance is absolutely horrible on the CV1 compared with the DK2, was running fine with DK2 and SDK 0.8 (from 75 fps down to about 20). Tracking also is completely broken for me, left and right is switched, startup position is also different.
