the only thing i did change or test afew difference settings was camera clear flag I have changes it to Depth only and solid color 

OK; I guess that's the issue. Vuforia (until version 3.0) internally sets the Clear Flags to DepthOnly, so that it can render the Video Background and then the augmentations on top of it. 

In general, you should not mess up with the Clear Flags settings, as the ARCamera needs those settings for a specific reason.

 

If you want to achieve a more "customized" rendering, you could however give a try with the Background Texture Access sample app, which you can dowanlod from here:

https://developer.vuforia.com/resources/sample-apps/background-texture-access-sample-app

That sample  shows how to redirect the Camera background video texture to a Texture in your scene, and then render a "screen-aligned" plane with that texture on it, using a second camera.

I have downloaded NEW sample scenes and NEW packages today and installed into the existing project and got this issue

I got the same issue afew months ago and had to drop AR from the project completely, we really want to bring it back and have come back and found the same issue.

 

I load up the sample scene, the only thing i did change or test afew difference settings was camera clear flag I have changes it to Depth only and solid color Both work fine  makes no difference to the webcam test ,. but once i build and run on ipad I get the Black BG and Render echo's ?? nothing else I have change from loading up the sample scene.

 

I will now build a Clean project and load the sample scene so no project assets shader etc I'm running out of option maybe it may be a asset like Marmoset, Ngui, etc  i have in the project messing with Vuforia ??? update you when I test it...

 

 

OK sample scene do work in a clean project SO  guessing Marmoset, NGUI, playmaker or the many other assets i have in the project are effecting the scene .. (which should not be the case since i am loading the sample Scene only and all it's settings that do not use any assets in the project ??)

 

anyway will update when i find how to get it working...

OK, thanks,

So, basically you're saying that on two major flagship iOS devices (iPad mini and iPad 3), you get black screen, and this happens regardless of the OS installed (iOS 7 and 8)

?

And this happens on a Vuforia Sample "as is" (are you sure you did not make any modifications to the Scene, the Camera ?) For example, have you added any Image FX to the camera ?

Hi,

what iPad mini model (iPad mini 2 or iPad mini 3) ?

Also, I understand you are on iOS 8.0; what version of Xcode have you installed on your Mac ? Xcode 6, or Xcode 5?
