three.js所使用的異常時sceneLoader裝載由three.js所編輯

Question

創建場景中的錯誤是Uncaught TypeError: Cannot read property 'opacity' of undefined上three.js所：12917

我使用的場景文件是：

{ 
"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, 
     "depthSegments": 1 
    }], 
"materials": [ 
    { 
     "uuid": "95D0C78A-2066-4A8D-9F46-73B3038E55DE", 
     "type": "MeshBasicMaterial", 
     "color": 16777215, 
     "opacity": 1, 
     "transparent": false, 
     "wireframe": false 
    }], 
"object": { 
    "uuid": "E0E0DAAE-012A-49DB-BC1B-2878BCA7F0DA", 
    "type": "Scene", 
    "matrix": [1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1], 
    "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] 
     }] 
} 

}

我查過了，它確實加載成功，並且是有效的JSON（JSONLint）; 我還測試了JSONLoader以成功加載JSON模型。 我似乎在使用the latest version。這個場景是在THREE.js編輯器中創建的，恐怕我不知道如何在它之外創建一個場景。

Answer 1

每https://github.com/mrdoob/three.js/issues/4259你應該使用ObjectLoader：

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

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

Answer 2

顯然問題出在編輯器創建的場景文件上。 我剛剛嘗試通過three.js場景示例運行場景文件，並得到相同的錯誤。
