Returns the index of the [GLTFNode] corresponding to this Godot scene node. This is the inverse of [method get_scene_node]. Useful during the export process.
[b]Note:[/b] Not every Godot scene node will have a corresponding [GLTFNode], and not every [GLTFNode] will have a scene node generated. If there is no [GLTFNode] index for this scene node, [code]-1[/code] is returned.

Returns the Godot scene node that corresponds to the same index as the [GLTFNode] it was generated from. Not every [GLTFNode] will have a scene node generated, and not every generated scene node will have a corresponding [GLTFNode].
