Three.js Loaded Model Missing Bump and Specular Maps

Question

I'm having trouble getting bump and specular mapping working on an imported model in three.js.

I'm exporting a model from 3DS Max to a .obj file, then using the convert_obj_three.py script to convert it to .js. Inside the model.js file I can see that bump and specular maps are coming across:

"materials": [  {
    "DbgColor" : 15658734,
    "DbgIndex" : 0,
    "DbgName" : "flloor_bump_test",
    "illumination" : 2,
    "mapAmbient" : "sat_8.jpg",
    "mapBump" : "sat_8_bump.jpg",
    "mapDiffuse" : "sat_8.jpg",
    "mapSpecular" : "sat_8_spec.png",
    "opticalDensity" : 1.5,
    "specularCoef" : 25.0,
    "transparency" : 0.0
},

Here's how I load the model into my scene:

var jsonLoader = new THREE.JSONLoader();
jsonLoader.load( "model.js", addModelToScene );

function addModelToScene( geometry, materials )
{
    var material = new THREE.MeshFaceMaterial( materials );
    model = new THREE.Mesh( geometry, material );
    model.scale.set(0.01,0.01,0.01);

    model.castShadow = true;
    model.receiveShadow = true;

    scene.add( model );
}

Any ideas greatly appreciated! Thanks!!

EDIT 2

So after playing with it I can see that the following data was missing from the converted .js model:

"shading" : "phong",
"mapSpecular" : "powerday_sat_8_specular.png",
"shininess" : 1000,
"mapBumpScale" : 5,

So obviously there is a problem in my export from Max to .obj, or the conversion of .obj to .js. If anyone has solved this problem I would really appreciate how you did it! Thanks :)

Answer 1

I ended up manually editing the .js model and adding in fields to make it look like the following:

"materials": [  {
    "DbgColor" : 15658734,
    "DbgIndex" : 0,
    "DbgName" : "21___Default",
    "colorAmbient" : [0.588235, 0.588235, 0.588235],
    "colorDiffuse" : [0.588235, 0.588235, 0.588235],
    "colorSpecular" : [0.117, 0.117, 0.117],
    "illumination" : 2,
    "mapAmbient" : "texture_8.jpg",
    "mapDiffuse" : "texture_8.jpg",
    "shading" : "phong",
    "mapSpecular" : "texture_8_specular.png",
    "shininess" : 1000,
    "mapBumpScale" : 5,
    "mapBump" : "texture_8_bump.jpg",
    "opticalDensity" : 1.5,
    "specularCoef" : 1000,
    "transparency" : 0.0
}
