来自搅拌机json的Three.js网格未显示

Question

我正在使用three.js，我将一个混合转换为json，我想在three.js中使用。当我在不使用json中的材料的情况下显示它时（我只使用了BasicMaterial（））它可以正常工作。当我尝试使用json中的材质时，它似乎没有呈现它。

这是我用来显示网格的代码：

var tower;
var loader = new THREE.JSONLoader();
loader.load( 'js/blends/towerlevel1-5.json', function ( geometry, material)   
{
        tower = new THREE.Mesh( geometry, material );
        scene.add( tower);
}); 

这是json材料：

        "visible":true,
        "shading":"phong",
        "wireframe":false,
