After container.instantiateModelsToScene where is original meshes

There are 9 elements in meshes in the original container,These are his heads, his eyes and so on,but after container.instantiateModelsToScene,three is only one rootNode left,I want to change the material of eyes, what should I do?

If you pass true as the second argument then it will clone the materials. Here the clone is red for example. :slight_smile:
