Question

对于three.js：12917

，错误为Uncaught TypeError: Cannot read property 'opacity' of undefined

我使用的场景文件是：

{
"metadata": {
    "version": 4.3,
    "type": "Object",
    "generator": "ObjectExporter"
},
"geometries": [
    {
        "uuid": "7F5BC6A2-4B74-4049-8AF8-40A5EF310430",
        "type": "CubeGeometry",
        "width": 100,
        "height": 100,
        "depth": 100,
        "widthSegments": 1,
        "heightSegments": 1,

    }],

    "children": [
        {
            "uuid": "E60D8291-4E35-4365-A98E-7AEA1D1D433F",
            "name": "Cube 1",
            "type": "Mesh",
            "geometry": "7F5BC6A2-4B74-4049-8AF8-40A5EF310430",
            "material": "95D0C78A-2066-4A8D-9F46-73B3038E55DE",
            "matrix": [1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1]
        }]
}

}

我已经检查过，它确实加载成功并且是有效的JSON（JSONLint）; 我还测试了JSONLoader以成功加载JSON模型。我好像在使用the latest version。这个场景是在THREE.js编辑器中创建的，我担心我不知道如何在它外面创建一个场景。

Answer 1

每https://github.com/mrdoob/three.js/issues/4259你应该使用ObjectLoader：

 function loaded(scene) {
    ...
    renderer.render(scene, camera)
 }

 new THREE.ObjectLoader().load("scene.js", loaded)

Answer 2

显然问题在于编辑器创建的场景文件。我刚试过通过three.js场景示例运行场景文件并得到了同样的错误。

THREE.js使用sceneLoader加载由THREE.js编辑器创建的场景时出现异常
