How do I get the position of the layer

[gfyrtuwcv]

I used ThreeDTilesLayer to add a tileset.json 3dtiles model to the map, it comes with location information, I can't find it using getExtent() function, how do I know where it is and if it loaded successfully？

There isn't a getExtent() function for the 3d tiles layer.
Take a look at how the LayerGUI gets the bounding sphere of the node and zooms to it. https://github.com/gwaldron/osgearth/blob/master/src/osgEarth/ImGui/LayersGUI#L874-L884
