I am working with image targets and it seems like the 3D models when activated randomly appear upside down in the ARCamera. I am using vuforia 3.0.6, but this was also happening in a previous version. Unity is version 4.5
This is happening in the Editor, where I am testing using my laptop Facetime camera.
I have tried changing the World Center Mode to various settings, thinking this was the camera flipping, but it is not. Using the Camera as the World Center Mode for the ARCamera, I can clearly see that it is not moving or rotating.
Here is the issue, when using Camera as the World Center Mode:
1. I hold the marker up in front of the camera, the model appears correctly oriented (most of the time)
2. I move my marker away, and about 50% of the time when it is again recognized, the model is displayed upside down.
If I repeat this, it continues to flop back and forth between correct orientation and upside down.
Looking carefully at the ImageTarget marker, I can see that when it is correctly oriented, it hovers around with an X rotation of about 45 degrees. When it's flipped, the X rotation is 305 degrees or so.
So, the model, which is a child of the image marker, seems to randomly flip orientation.
How can I fix this? Is this behavior only in the Editor?
