GLTFLoader.js:2145 TypeError: Cannot read property ‘children’ of undefined

Description of the problem

Please help. I got below error when I tried to load a .gltf file. I used the sample code: https://threejs.org/examples/#webgl_loader_gltf2

Also, here is the link of the files I used:
http://densetsughem.com/Dog.zip

THREE.Object3D.add: object not an instance of THREE.Object3D. undefined

  1. Hi @densetsughem — thanks for the details! You have a glTF1.0 model here, and we’re not supporting that much longer. Rather than try to debug what might be wrong with GLTFLoader or with the model, could you try making a glTF2.0 version?

    There is a new glTF Blender exporter that should help: https://github.com/KhronosGroup/glTF-Blender-Exporter

    To test glTF2.0 files in THREE.GLTF2Loader, you can drag-and-drop them here: https://gltf-viewer.donmccurdy.com/
