I imported the FBX model to the project. Later it creates the json format which we can add to the hierarchy.
But, in the hierarchy, the childs of the object are not seen in the hierarchy. It really is a problem to manipulate the parts of the model in the scene according to the requirements. Is there anything like that.
The inner hierarchy of a model is not exposed at the moment. We have plans for adding this support in Editor.
So right now either separate into different fbx’s, or use code to manipulate stuff. As in engine it is a hierarchy.
