You can traverse through the parsed `glTF` scene and replace materials with a new one (using an alpha map). Try to use a code like the following in your `onLoad()` callback:

```auto
var newMaterial = new THREE.MeshStandardMaterial( { alphaMap: map } );

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

   if ( object.isMesh ) {

     object.material = newMaterial;

   }

} );

```
