Can SenseNode have a tree structure ?

What I see now is only two floors, unlike Unity! Allow multi-level parent-child relationships.

It supports tree structures. Not sure what you mean by two floors.

Child nodes cannot be added anymore, there are their own child nodes below the child nodes.

You need to use group node to create tree structures.

When loading a model, the child node defaults to SenseNode. Do I need to create a group independently of the parent model.

Depends on what you are trying to do. If you need to modify the model tree structure, you probably want to create your own importer.
