Export from Maya (with animatio) to Three.js with FBX

Hello Guys
I have a blank screen with these 2 fbx files while loading with a Three.js viewer. Is there a way to debug ?

It’s possible to render both FBX files without issues in the three.js editor: https://threejs.org/editor/

You just have to add some lighting to your scene (e.g. an ambient and directional light).
