I have followed the Integrating Cardboard to the AR/VR Sample latest tutorial. I have configured the provided scene sample according to that tutorial. I have compiled it to Android without any problem.
The game load an AR scene with a yellow pointer in the center. If I understood well, if a glaze at the ImageTargetStones GameObject, it will switch to VR. Unfortunately I cannot find that GameObject anywhere. I only see the AR scene with nothing than the yellow pointer.
I don't find what I'm missing. Why is not that ImageTargetStones GameObject in the AR scene?
I think I want to use Vuforia for an uncommon use. I think that's a reason of a possible misunderstanding.
I don't want to use its image recognition possibilities. I want to switch between AR to VR when glazing to a button.
I have tried to duplicate the VRButton to move it to an independent place of the scene with no parent. I have checked its IsTrigger checkbox. I have added a PointerEnter EventTrigger that set Focused to true. I have added a PhysicsRaycaster to both AR Camera and MainCamera (child of CardboardMain-Head).
Nothing happens when I gaze at the button. I have to compile everytime I want to try it by the way. I did not manage to make it work in the editor.
I haven't been able to do it with vuforia yet. I have done it with WebCamTexture. Specifically, I have used the scripts of this answer: http://answers.unity3d.com/answers/687987/view.html . The result is not nice because the image from camera seems closer than it actually is (with Vuforia, there is not that problem)
