A typical error producing this result are PBR materials not configured properly. Please try to alter the materials of your gltf asset like so after loading:

```auto
gltf.scene.traverse( ( object ) => {

   if ( object.isMesh ) {

     object.material.roughness = 1;
     object.material.metalness = 0;

   }

} );

```

I’d also suggest checking your model in [gltf-viewer.donmccurdy.com/](http://gltf-viewer.donmccurdy.com/). If the model appears correctly there, something is probably wrong with your lights. If it’s incorrect there, the model is not being exported correctly. Knowing which will help to narrow things down. 🙂
