Will try my best to explain this in hope someone can help.
Lets take a trigger image that is on a wall and when detected a 3D model of a person is placed in view. In the camera view you can see the trigger image behind the person model and that the models feet are correctly orientated to face the floor, as if standing up.
This is easy enough as if one presumes the trigger image is going to be on a wall in the editor I can place the 3D model in the expected orientation.
But, if the trigger image is taken off the wall and placed on a desk now the 3D model appears to be lying down because as it is set in the editor that is how it would appear.
Is there a way to get the 3D model to change its orientation angle based on the angle of how the device is held?
