【中文标题】带纹理的 JSONLoader【英文标题】：JSONLoader with texture 【发布时间】：2013-01-30 02:49:28 【问题描述】：我在 Blender 中制作了一个带有纹理的形状并将其导出。然后用 json loader 显示它。几乎一切都很好，几何形状很好，可以在形状上看到纹理，但没有颜色。只是黑色和枯萎。如何显示纹理颜色？我做错了什么？

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：
【问题讨论】：
【参考方案1】：您的 JSON 文件中的材料看起来不正确：
你有
"mapNormal" : "texture3.jpg"
应该是的
"mapDiffuse" : "texture3.jpg"
three.js r.55
