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"

Just tested the "Instanced Stereo" VR setting under Rendering project settings exporting to Android (ES2 -> development) and I see the following build failed error message:

Hello aussieburger,

I was able to reproduce this issue on our end. I have written up a report (UE-25738) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your information and time.

Make it a great day

Instanced sterero is not supposed to work on Android. A fix has been checked in to indicate this in the tooltip and to force it off during packaging if on for unsupported platforms. At the moment on D3D SM5 and PS4 support this.
