我目前正在围绕three.js缠绕我的大脑,我已成功通过三个.OBJMTLLoader导入我在C4D中制作的3D模型,但是我无法让对象投下阴影。我已经使用了object.castShadow = true但是它没有用,但我可以在three.js中创建几何体以投射阴影,所以我知道场景设置正常。
测试场景目前位于http://kirkd.co.uk/dev/,现在已根据下面的建议进行了更新。
代码在下面,如果有人可以指出我做错了什么,或者即使导入的对象可以投射阴影,那么我也会永远感激。

您的对象包含子网格,每个网格都需要将castShadow
设置为true
。
在你的加载器回调中,添加:
object.traverse( function( node ) { if ( node instanceof THREE.Mesh ) { node.castShadow = true; } } );
