I actually have an unity3d application using 2 framemarkers.
When only one is visible (the landscape), all child objects are well placed.
When I insert in the camera frustrum the second framemarker (the vehicle), some (randomnly choosed) objects are misplaced.
It seems that they're aligned width the vehicle, as if there was a confusion between the two patterns.
Do you have any idea of what is the cause of this problem ?
Here are 2 screenshots imaging the problem
Everything's good !!!
That's wrong !!!
