In one section of my level, the right eye in my Oculus will flicker with black sections. While this is happening, I also get bad tearing or streaking when moving my head. When I run this level in the editor in VR preview mode, it runs perfectly smoothly at 75fps with no flicker.
Another problem (which may be unrelated) is that some objects in the level move with my head a bit. It’s hard to explain, but they sort of shift around based on my head movements instead of staying put.
NVIDIA GeForce GTX 980
I just recently updated the NVIDIA Gameworks driver to 358.78 and Oculus runtime to 0.8.
We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.
So the native packing problem has been resolved but it still has lag (it might flicker I guess, because I have a bit lagging videos), I updated my Quadro drivers to 358.91. But the when I preview in the editor I still have the problem.
I have the same issue. Windows 7 with latest nVidia drivers. Seems to be related to 2D, screen-space UI Widgets. I switched them to World-space UI widgets and all the flickering goes away. The flickering and artifacts are not visible in the preview window, but they are visible in the headset.
Well this won’t really solve the problem if you don’t want 3D, in-world widgets. But you can look at the properties for your widget and under the “UI” heading change the Space to World instead of Screen. I’m interested if that also fixes it for you.
I had an idea after reading over you last post. It turns out the reason I could not reproduce this issue is because I was trying it is standalone. After running the test in VR preview, I was able to reproduce this issue on our end. I have written up a report (UE-25832) 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 time and information.
