我尝试了以下方法，它们都产生了类似的结果。
var loader = new THREE.JSONLoader();
loader.load("models/pine.json", function ( geometry, material ) {
var mat = new THREE.MeshFaceMaterial( material );
mesh = new THREE.Mesh( geometry, mat );
scene.add(mesh);
});
var loader = new THREE.JSONLoader();
loader.load("models/pine.json", function ( geometry, material ) {
var mat = new THREE.MeshFaceMaterial( material );
mesh = new THREE.Mesh( geometry, mat );
scene.add(mesh);
});
var loader = new THREE.JSONLoader();
loader.load("models/pine.json", function ( geometry, material ) {
var mats = [];
for (var m in material)
mats.push(new THREE.MeshLambertMaterial( m ))
var mat = new THREE.MeshFaceMaterial( mats );
mesh = new THREE.Mesh( geometry, mat );
scene.add(mesh);
});

答案 0 :(得分：1)
您在调用材料时使用'mat'。这是它应该是什么：
var loader = new THREE.JSONLoader();
loader.load("models/pine.json", function ( geometry, materials ) {
var material = new THREE.MeshFaceMaterial( materials );
mesh = new THREE.Mesh( geometry, material );
scene.add(mesh);
});
PS：你的模特真的很黑。与真正明亮和白色的一切相比，尝试使其更加明亮的绿色和棕色，以适应景观。
