Adding images and textures to a Three.js JSON object file is a simple yet essential process that can greatly enhance

My main objective is to import a 3D model from 3DS/MAX into WebGL using the powerful Three.js library. I've made progress towards this goal through the following steps.

Initially tried exporting from MAX plugin exporter straight to Three.js JSON, but encountered issues and it didn't work.
Exported the MAX model in OBJ format instead.
Converted the OBJ model to JSON format using Obj2Three.js converter from Three.js.
This method successfully loads the model in Three.js, but without any textures or images applied.
Upon inspection of the JSON file, it contains Geometries, Materials, Metadata, and Object sections.
The Three.ObjectLoader can handle Images and Textures if those sections are defined within the file.

Now, my question arises - how can textures be added to the JSON file? Are there any tools available to facilitate this process?

If you're working with three.js, there's no need to go through the hassle of converting file formats. Head over to the examples folder and you'll find a variety of loaders at your disposal. Opt for the OBJLoader for a popular choice, or consider the FBXLoader or ColladaLoader2 for smaller file sizes compared to .obj or JSON files. Check out this example using the FBXLoader along with adding a texture:

loadFBX = function(modelPath, texturePath) {

  var container = new THREE.Object3D();

  fbxLoader.load(modelPath, function( object ) {

        container.add(object);

   object.traverse (function (child) {

        if (child instanceof THREE.Mesh) {
           //Here's how we add the texture, remember to UV Unwrap your model in 3Ds first
           child.material = new THREE.MeshLambertMaterial();
           child.material.map = textureLoader.load(texturePath);
        }

     });

    }, onProgress, onError );

    return container;
}

var model = loadFBX('../models/model.fbx', '../textures/texture.png');
scene.add(model);

Instead of converting, why not just load .obj or even .fbx formats directly? However, if you still want to convert, there's an easy way to add textures to your JSON model. Utilize the online Three.js Editor by simply dragging your .obj or desired model into the scene. Then, use the visual editor to apply the image texture before exporting it as .json. Once loaded into the scene, the texture will be incorporated in the JSON file.
