Hi Lounes99,
Have you tried the behavior string expression "3D Object ID"?
Also, some 3D actions have no effect on objects using behaviors. Because the 2D object values take precedence.
e.g. position, rotation etc.
It doesn't work1 year ago(+1)
As explained earlier, that will not work. If you want to rotate freely, create and control 3D objects using only 3D actions, not behaviors.
