I just follow this example: http://threejs.org/examples/webgl_loader_obj_mtl.html
But my object loads without texture. I used a .obj and a .mtl file generated by Blender. What can I do to apply a texture to this object in Three.js? Here is the object I want to load: http://tf3dm.com/3d-model/super-camputer-ibm-75503.html
How I load the object:
var loader = new THREE.OBJMTLLoader();
loader.load('obj/servidor.obj', 'obj/servidor.mtl', function(object) {
object.position.y = -80;
scene.add(object);
}, onProgress, onError);
