We try to achieve something quite simple : when the user touch a 3D model, snap it to the screen with a background image hiding the camera's. Then the use should be able to manipulate the model to see it from different angles.
We got our image target's cam drawables as : [ imageDrawable, model ].
When we snap our image target to the screen, the background is rendered under the model on android, but on top of the model on iOS.
We tried playing with the z coordinate without success and there is no zOrder property on AR.Model.
The documentation mentions that 3D is always rendered on top of 2D, but it seems that his behavior is inconsistent when snapped. What should we do ?
