Question

我无法将我的blender导出网格设置为动画。甚至不包括我在该示例中可以清楚地看到动画的水牛。（我一直试图重现无济于事。这是代码，我怀疑它是一个非常简单的缺失的东西，但我不知道。我怀疑它是一个混合器问题，因为我甚至无法为包含的网格设置动画。

Answer 1

尝试阅读这篇文章，也许它会有所帮助： http://devmatrix.wordpress.com/2013/02/27/creating-skeletal-animation-in-blender-and-exporting-it-to-three-js/

Answer 2

问题可能在这里：

var faceMaterial = new THREE.MeshFaceMaterial( materials );
faceMaterial.skinning = true;

meshFaceMaterial就像是其他材料的容器 - 它本身并不是真正的材料。尝试迭代其材料集合：

var materials = faceMaterial.materials;
for (var i = 0,length = materials.length; i < length; i++) {
    var material = materials[i];
    material.skinning = true;
}

Three.js Mesh没有使用AnimationHandler进行动画处理
