Wrong stereo rendering in Unity 5.6 game viewer

[GordeyChernyy]

After importing package I tried to open a demo and stereo preview in Unity 5.6.0b5 viewer looks wrong.

Console sometimes gives me this error: Rendering camera 'Main Camera Right', but calling code does not set it up as current camera (current camera: 'PreRender')

Phone build looks normal. I don't have these issues in Unity 5.4.

Thanks @GordeyChernyy, Unity is looking into a fix.

This looks to be an issue introduced in 5.6. I'm not sure if this was an intended change in Unity or a regression. Until we have a resolution the following changes will correct this for users of the SDK.

I tested the changes @joejo-unity posted, and it works. There's no more visual glitch! Thanks!

Tested on Unity 5.6.0b6 64-bit
GoogleVR SDK v1.20
Linux Mint 18.1 64-bit (Ubuntu 16.04 base), Cinnamon 3.2.7 desktop environment, Nvidia GTX 980Ti & Nvidia 367.57 proprietary graphics drivers.

beginner question: How can I apply those changes in my version control?
I'm using a GIT repository with Sourcetree. thanks

Thanks this fixed the Rendering camera 'Main Camera Right' . I have another strange issus and it is very hard to debug, My Main Camera Right is darker and recive no light

[scorpeeon]

skaale: I have very similar issues after applying the fix: on the left eye everything looks good, but on the right, many things don't appear as they should or don't appear at all. (this only happens in the editor's play mode, not on the phone)
Strange thing is this is also not happening when not applying the fix (but the picture is in pieces then), and also not happening on some scenes like the default google vr sample scenes.

HI thanks.. yes properly do to beta reverse to 5.5,1 with older version of GoogleVR .. thanks for replie:-)

I'm using latest beta (5.6.0b9) - it was like this in the few previous betas too I was using.
The issue seems like on the right eye, the lights of the scene have no effect or are ignored.

[zx-sd]

The solution from @joejo-unity works for me.

Unity 5.6.0b9
GoogleVR SDK v1.20

[skaale]

Great so you have same light output for both eyes Sendt fra min iPhone

@joejo-unity thanks forever.

@frolicks the script @joejo-unity has attached is meant to be applied in the terminal with the patch command. A newbie myself, I have no clue how you do that. I just opened the scripts it involves in Unity (GvrEye and StereoRenderEffect) and removed/ added the lines as described. Good luck!

e.g. look at the script below: 210,6 is the line numbers in the script, from 210 to 216, and what comes after "+" is what you need to add there (just the stereoEffect.eye = eye; in this case).
"-" means that you erase a line. Read the script letter by letter, it's not such a tricky task after all and you'll feel like a superhero after.

Just tested GoogleVR SDK 1.30 with Unity 5.6.0xb10 on Ubuntu 16.10, and it works great! There's no distortion in the stereo viewer at all. Thanks to the team for fixing this bug! See their release announcements, too - https://developers.google.com/vr/unity/release-notes.

[GordeyChernyy]

Tested with Unity 5.6.0f3, the issue is gone. Thanks!

[tejusk06]

Using Unity 5.6.1f1. Issue resolved! Thanks :)

Follow this tutorial. You can get google VR SDK package in the link of video. Just import it and run on your android . Hope it will help
