带纹理的JSONLoader

Question

我在Blender中制作了一个带纹理的形状并将其导出。然后用json loader显示它。几乎所有东西都很好，几何形状很好，你可以在形状上看到纹理，但没有颜色。只是黑色和有。如何显示纹理颜色？我做错了什么？

    "skinIndices" : [],

    "skinWeights" : [],

}

加载网格的代码是：

var loader = new THREE.JSONLoader();
loader.load('cylinder.js', function(geo, mat){

    var materials = new THREE.MeshFaceMaterial( mat );

    var mesh = new THREE.Mesh(geo, materials);

    mesh.position.y=0;
    mesh.position.x=5;
    loadJson(mesh );
});

 function loadJson(mesh){
     scene.add( mesh );    
 }

结果：

Answer 1

您的JSON文件中的材料看起来不正确：

你有

"mapNormal" : "texture3.jpg"

它应该是

"mapDiffuse" : "texture3.jpg"

three.js r.55
