我已经通过文件以及许多的例子看，并没有能够找到正确的语法分配材料到一个Collada的.dae或OBJLoader obj文件。

I have looked through the documentation as well as many examples and wasn't able to find correct syntax for assigning a material to either a Collada .dae or OBJLoader .obj file.

Json的文件似乎建立在正常上班网​​和具有加载器的几何形状和材料作为一组材料。

Json files seem to properly work when creating a Mesh and having the loader as geometry and material as the set material.

code这样的工作原理

Code like this works

var loader = new THREE.JSONLoader();
loader.load( "modelPath.js", function(geometry){
  var material = new THREE.MeshLambertMaterial({color: 0x666666});
  mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);
});

这不能正常工作

var loader = new THREE.ColladaLoader();
loader.load( "modelPath.dae", function(geometry){
  var material = new THREE.MeshLambertMaterial({color: 0x666666});
  mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);
});

和这不起作用

var loader = new THREE.OBJLoader();
loader.load( "modelPath.obj", function(geometry){
  var material = new THREE.MeshLambertMaterial({color: 0x666666});
  mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);
});

我也尝试 geometry.material =新THREE.MeshLambertMaterial（{颜色：为0xFF0000}）; 在函数（几何）没有成功。

.Dae格式似乎直接让材料颜色从电影院一样的3D节目。如何设置一个材料，这些装载机正常吗？如果这是可能的，甚至

.Dae format seems to keep material color directly from 3D programs like Cinema. How can I set a material to these loaders properly? If this is even possible.

推荐答案

按照这个模式来 OBJLoader ：

var loader = new THREE.OBJLoader();

loader.load( 'model.obj', function ( object ) {

    var material = new THREE.MeshLambertMaterial( { color: 0x666666 } );

    object.traverse( function ( child ) {

        if ( child instanceof THREE.Mesh ) {

            child.material = material;

        }

    } );

    scene.add( object );

} );

有关 Col​​ladaLoader ，该模式是相似的。

For ColladaLoader, the pattern is similar.

var loader = new THREE.ColladaLoader();

loader.load( 'model.dae', function ( collada ) {

    var dae = collada.scene;
    scene.add( dae );

} );
