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"

[Gear VR] Multiview is buggy

When using ES3.1 and Multiview for Gear VR, scene renders black (although it could be ES3.1 and not multiview issue)

When using ES2 and Multiview option, performance is significantly lower than without Multiview (59.xx fps vs 39.xx fps).

It also seems that MSAA is not working at all with Multiview enabled. Here are 2 screenshots taken on the device:

With multiview: https://drive.google.com/open?id=0BwE6dxM0O2PsRlNiSlRoanZVSEk

Without multiview: https://drive.google.com/open?id=0BwE6dxM0O2PsRXJ2MTBHbVFXTUk

(you can see aliasing on the arrow and on the floor rubble tiles)

Product Version: UE 4.14

For me the bottom half of the screen is fully aliased while the top is clear.

Apparently Multiview is not designed to work with ES3.1 per Oculus (due to drivers on the phones) and it's not production ready for ES2 either. Maybe in UE 4.99 ... err, nearest future, it will get better! :)

cool, except that report doesn't even mention AA issues.

since TAA is not working with Mobile HDR enabled, I rejected the tests.

MSAA works on mobile VR. TAA never worked and it's not the best AA method for VR anyway.
