Hey there i'm new to three js & was wondering how to cast a shadow with a gltf model? I can see it's possible as it's working here I assume i'm not structuring my code correctly-

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

推荐答案

您需要在每个子网格上设置 castShadow = true，如下所示:

You need to set castShadow = true on each child mesh, like so:

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.isMesh ) { node.castShadow = true; }

    } );

    scene.add( gltf.scene );

} );
