Google Cardboard Lens Distortion = Invisible UI

Hello, I'm trying to make a simple VR Player, but when I run my project, for some reason UI disappears, only in VR Mode, but if VR Mode is deactivate and I play it un 360 mode, all UI is visible.

Some one knows a solution?? because I need it with VR mode.

 

Hi,

Can you describe more or give video example?

 

In the images below You can see GUI in 360 mode and VR. In VR both camera see the GUI, but with distortion GUI is invisible.

 

Try with your ui in google cardboard demo scene.

 

We have the same issue. We reverted back to 5.3.4P1 to fix the issue. Started the project again and everything worked. Really strange. I looked at the release notes, but nothing jumps at me that could result in this issue.
I haven't tried the default Cardboard demo.

 

Thanks, I run my project on Unity 5.3.4p1 and it worked. Maybe a patch bug, I hope can be fixed in next patch

 

Just encountered this bug in 5.3.4p4. Installing 5.3.4p1. I now have 3 versions of Unity installed. Very frustrating.

 

Hello there,
i reported this bug with repro case a short while ago and it was looked into and i was told it's fixed with the latest 5.4 beta. So either you have to go with that or for the meantime use an older 5.3.4 build from before the bug was introduced.

 

Awesome! Thanks for the update!

 

you're welcome =)

 

I also encountered this bug in Unity 5.3.4p4.
The bug is still present in Unity 5.3.4p6.
Reverting to Unity 5.3.4p1 did the trick.
I have not tested other 5.3.4 patch-releases.

 

This bug is still present in 5.3.5p2.
It has been marked as fixed for 5.3.6.

Do you think it has anything to do with the distortion correction? Do you have it set to "Unity" or "Native"?

 

No, according to the feedback by the Unity fellas on the bug report i sent on this it is a bug on Unity side where the Canvas ui does not get rendered in Rendertextures (which google cardboard's cam setup uses) and yes, the fix should be in 5.3.6. As helgewl said, until that's available best use an older version from before the bug was introduced like Unity 5.3.4p1.

 

The fix is scheduled for 5.3.5p5 (source)
