Hello! Please help me understand how to apply another material and alphaMap to exported model from blender

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:

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

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

   if ( object.isMesh ) {

     object.material = newMaterial;

   }

} );
