I've had this issue before.  How are you setting your orientation?  Are you setting the supported orientations via Inspector or setting them via script?

EDIT: I've used the ARCamera in landscape mode successfully many times.

Hi Banister,

Yes this was acknowledged as a Unity Problem on 3.5.2 and I provided a workaround here:

https://ar.qualcomm.at/content/unity-352f2-and-ios-fixed-orientation-causes-distorted-output

When 3.5.3f3 came out I tested it and it worked fine.

I took a basic ImageTargets app and set it to a fixed orientation and the problem went away without needing the work around.

I just retested this after seeing your post and tried fixed orientations Landscape Left and Right, and both worked fine on 3.5.3f3.  The only difference is between these were the orientations of the buttons.  Apart from this the camera initialised correctly.

Please could you check you installation and maybe try with a new sample from scratch to see if there is a problem, plus it's also worth checking the device for any old copies of code, because definitely this problem should not be there.

I'm setting them in Unity, in the player settings for the iOS device. I never set them in code, do I have to? I'll run the sample again to see if it is working on there and post the results.

I created a brand new unity project, imported the vuforia 1.5.9 package (I tried this exact process with both the one from the asset store and the one from your website just to make sure there wasn't some discrepancy with one or the other), imported a packed that holds some markers that I made on your website, dragged in an ARCamera prefab, dragged in an ImageMarker prefab, set the dataset up on the two drop menus on the ImageTargetBehaviour script, made a cube - changing its size and location to be right in the middle of the image marker, threw a light in there for good measure. I then went into the build settings and set the orientation for LandscapeLeft, it built and I opened it in xcode (saw the the orientation was set for landscape right now) changed my target device, set up my provisioning profiles, and hit run

I'm still experiencing some odd behavior with the camera, it still appears turned unless i tilt my head. Any suggestions? I'm using everything as stock from the project, no custom scripts or anything. Thanks

Hi Banister,

Can you PM me with a link to the project so I can download and test it this end?

Cheers,

N

EDIT 

BTW What happens with the ready-made Image Targets scene?  i.e. the one that comes as part of the package?

Basically this is in the Project Hierarchy in Unity and if you double click there is a ready made scene which you can just build and run using chips and stones.  Does the problem exist here?

I ran the stock image test with the teapots and I had the same problem. I've included a picture and I'll PM you this teapot project and you can take a look and make sure I'm not screwing anything up.

Ok just to confirm after running tests that this is an issue with XCode 4.5 Developer Preview / iOS6 Beta

as after downloading and running the project with the current version of XCode the orientation was correct.

just as an update for anyone else who was following this thread or may come across it in the future, the problem was that my device was running the new iOS 6 which has some problems. I grabbed a device with iOS 5 on it and everything worked fine. So if you're experiencing this problem, make sure your devices OS is a supported version. 

I'm running iOS 6 as well. I'm running Unity 3.5.5f2. I have the same issues in Landscape. 

Is Qualcomm working on a fix for this issue?

Maybe this will help you: https://ar.qualcomm.at/content/starting-portrait-orientation-runtime-change-landscape-left-ios

The intention is to support iOS6 in due course, but there is no date for this.

EDIT

I have just started to look at iOS6 to identify what the problem is, and currently this is not clear to me - Image Targets is running fine on iPad2 on iOS6 beta 4

What devices are people having problems with?

N

After doing a bit of research and testing it appears that this is the same as the previous "Unity fixed orientation" issue - but this time on iOS6 whereas it ran fine in previous iOSs following the Unity fix from 3.5.3f3 onwards.

At present I am not sure why this happens, but it seems there is an underlying change in iOS6 which Unity has not caught up with, and Vuforia is just one of the applications that is affected under the circumstances, as would any other applications.

This thread points to another example:

http://forum.unity3d.com/threads/147201-Orientation-and-rotation-issues-when-Building-Unity-App-to-iOS-6-beta-4

Not sure what to suggest here...

I'd recommend filing a bug w/ Unity, obtaining the ticket number, and following-up with Unity Support.

Hi adDispatchARTeam

For the orientation issue could you please try this to see if it fixes the issue:

In AppController.mm around line 697 you will see this line:

UnitySetScreenOrientation(requestedOrient);

...so above it try adding this line:

        QCARUnityPlayer::getInstance().QCARSetOrientation(requestedOrient);

and let me know whether it fixes this issue or not.

thanks

The color is still out of sync on the camera feed. But this fixed the orientation issue!

Thanks

Joe

This is good.

Stay tuned.
