[Visualizer] Cannot visualize models in two separate Visualizer objects #654

Here, I tried to add the same model to two instantiated objects of the iDynTree visualizer. I set camera targets and positions. And when I call draw() on both the objects, only one of the object gets updated.

multiviz

Am I missing something here? Or is it not possible to have multiple instances of the Visualizer due to some underlying shared SceneManager ?

As discussed on Teams, in theory the two Visualizers should be completely independent, but it is possible there are some bugs in iDynTree or in Irrlicht, I personally do not remember if I have tried to do something like that.
