Recientemente obtuve el ejemplo de three.js del sitio oficial que trabaja con mis objetos de collada (.dae) usando elColladaLoader.js. Ahora mi pregunta es, ¿cómo puedo cambiar el atributo de color del objeto collada cargado y agregar una textura personalizada? Intenté agregar la textura sin suerte todavía.

Aquí está mi código (ligeramente cambiado del ejemplo original):

function load_model(el) {

            if ( ! Detector.webgl ) Detector.addGetWebGLMessage();

            var container, stats;

            var camera, scene, renderer, objects;
            var particleLight, pointLight;
            var dae, skin;

            var loader = new THREE.ColladaLoader();
            loader.options.convertUpAxis = true;
            loader.load( '/site_media/models/model.dae', function ( collada ) {
                dae = collada.scene;
                skin = collada.skins[ 0 ];

                dae.scale.x = dae.scale.y = dae.scale.z = 0.90;
                dae.updateMatrix();

                init(el);
                animate();

            } );

            function init(el) {

                container = document.createElement( 'div' );
                el.append( container );

                camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 2000 );
                camera.position.set( 2, 2, 3 );

                scene = new THREE.Scene();


                scene.add( dae );

                particleLight = new THREE.Mesh( new THREE.SphereGeometry( 4, 8, 8 ), new THREE.MeshBasicMaterial( { color: 0xffffff } ) );
                scene.add( particleLight );

                // Lights

                scene.add( new THREE.AmbientLight( 0xcccccc ) );

                var directionalLight = new THREE.DirectionalLight(/*Math.random() * 0xffffff*/0xeeeeee );
                directionalLight.position.x = Math.random() - 0.5;
                directionalLight.position.y = Math.random() - 0.5;
                directionalLight.position.z = Math.random() - 0.5;
                directionalLight.position.normalize();
                scene.add( directionalLight );

                // pointLight = new THREE.PointLight( 0xffffff, 4 );
                // pointLight.position = particleLight.position;
                // scene.add( pointLight );

                renderer = new THREE.WebGLRenderer();
                renderer.setSize( window.innerWidth/2, window.innerHeight/2 );


                container.appendChild( renderer.domElement );

                stats = new Stats();
                stats.domElement.style.position = 'absolute';
                stats.domElement.style.top = '0px';
                container.appendChild( stats.domElement );

                //

                window.addEventListener( 'resize', onWindowResize, false );

            }

            function onWindowResize() {

                camera.aspect = window.innerWidth / window.innerHeight;
                camera.updateProjectionMatrix();

                renderer.setSize( window.innerWidth/2, window.innerHeight/2 );

            }

            //

            var t = 0;
            var clock = new THREE.Clock();

            function animate() {

                var delta = clock.getDelta();

                requestAnimationFrame( animate );

                if ( t > 1 ) t = 0;

                if ( skin ) {

                    // guess this can be done smarter...

                    // (Indeed, there are way more frames than needed and interpolation is not used at all
                    //  could be something like - one morph per each skinning pose keyframe, or even less,
                    //  animation could be resampled, morphing interpolation handles sparse keyframes quite well.
                    //  Simple animation cycles like this look ok with 10-15 frames instead of 100 ;)

                    for ( var i = 0; i < skin.morphTargetInfluences.length; i++ ) {

                        skin.morphTargetInfluences[ i ] = 0;

                    }

                    skin.morphTargetInfluences[ Math.floor( t * 30 ) ] = 1;

                    t += delta;

                }

                render();
                stats.update();

            }

            function render() {

                var timer = Date.now() * 0.0005;

                camera.position.x = Math.cos( timer ) * 10;
                camera.position.y = 2;
                camera.position.z = Math.sin( timer ) * 10;

                camera.lookAt( scene.position );

                particleLight.position.x = Math.sin( timer * 4 ) * 3009;
                particleLight.position.y = Math.cos( timer * 5 ) * 4000;
                particleLight.position.z = Math.cos( timer * 4 ) * 3009;

                renderer.render( scene, camera );

            }
