  您需要在每个子网格上设置 castShadow = true ，如下所示：

  var loader = new THREE.GLTFLoader();
  
  loader.load( 'https://threejs.org/examples/models/gltf/Duck/glTF/Duck.gltf', function( gltf ) {
  
      gltf.scene.traverse( function( node ) {
  
          if ( node instanceof THREE.Mesh ) { node.castShadow = true; }
  
      } );
  
      scene.add( gltf.scene );
  
  } );
  

  three.js r.91

  var loader = new THREE.GLTFLoader();
              loader.load( 'file path/gltf.gltf', function ( gltf ) {
  
                  gltf.scene.traverse( function ( node ) {
  
                      if ( node.isMesh || node.isLight ) node.castShadow = true;
                      if ( node.isMesh || node.isLight ) node.receiveShadow = true;
  
                  } );
  
                  gltf.scene.traverse( function ( child ) {
  
                      if ( child.isMesh ) {
  
                          child.material.envMap = envMap; //reflection of the world
  
                      }
  
                  } );
  
                      scene.add( gltf.scene );
