Why is my PlaneGeometry not receiving a shadow?

I am using three.js to create a scene that has a model on it. I have a plane on which the model sits, and a spotlight shining on the model.
The model is made up of a number of different objects. All of the objects are set to receive and cast shadows. Shadows are being cast on the model itself from other areas of the model.
The plane, however, won't receive shadows. I'm unsure why.
I have adjusted the spotLight.shadowCameraNear and spotLight.shadowCameraFar properties to ensure both the model and plane are within the shadow area. Still nothing.
Below is a screenshot of the model with the spotlight visible.
I have the shadowmap enabled and set to the soft maps:
renderer.shadowMap.enabled = true; // Shadow map enabled
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
My code is as follows:
<script>
if ( ! Detector.webgl ) Detector.addGetWebGLMessage();

console.log(child);
}
});
object.position.y = -1;
object.position.x = 0;
scene.add( object );
scene.fog = new THREE.Fog( 0xffffff, 50, 100 );

} );
// END Clara.io JSON loader code
renderer = new THREE.WebGLRenderer({
'antialias': true
});
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.setClearColor( scene.fog.color );
container.appendChild( renderer.domElement );
renderer.gammaInput = true;
renderer.gammaOutput = true;
renderer.shadowMap.enabled = true; // Shadow map enabled
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
// controls, camera
controls = new THREE.OrbitControls( camera, renderer.domElement );
controls.target.set( 0, 0, 0 );
controls.maxPolarAngle = Math.PI * 0.5;
camera.position.set( 8, 3, 10 );
controls.update();
window.addEventListener( 'resize', onWindowResize, false );
animate();
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
}
//
function animate() {
requestAnimationFrame( animate );
stats.update();
render();
}
function render() {
var delta = 0.75 * clock.getDelta();
camera.lookAt( scene.position );
renderer.render( scene, camera );
}
</script>

This was fixed by using a THREE.MeshPhongMaterial instead of a THREE.MeshBasicMaterial.

Lean object towards mouse threejs

I am trying to recreate a mouse interaction with an obj file - similar to this example:

imported json model not casting shadow

I have exported two models from Blender, each to a separate json file using the latest three.js exporter, then I tried to load it and add to my test app. I have set all the required parameters to enable the shadow casting, but still the shadows are not appearing at all.. Any ideas as to what may be wrong here?

it appears that the spot_light had to be moved a little bit up along the Y axis. now it works perfectly.

Three.js OBJloader with OrbitControls

I need to do very simple 3d model viewer with rotation and so on..
I have simple code, everything works fine, but when I add these two rows with OrbitControls then there'S only blank page:
controls = new THREE.OrbitControls( camera );
controls.addEventListener( 'change', render );
Whole code:

Any idea where is the problem?
I tried some few tutorials, but no one helped me..

You need to include three.min.js first:
<script src="js/three.min.js"></script>
<script src="js/OrbitControls.js"></script>
<script src="js/OBJLoader.js"></script>

Clickable three Js Objects / Convex Items

I modified an example from Three.js library and I tried to add click event on objects.
After a lot of attempts... I'm still not capable to listening for clicks.
This code produces convex forms.
There is my code:
if ( ! Detector.webgl ) Detector.addGetWebGLMessage();
var container, stats;
var camera, scene, renderer;
var objects = [];
init();
animate();
function init() {
container = document.createElement( 'div' );
document.body.appendChild( container );
camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 2000 );
camera.position.y = 400;
scene = new THREE.Scene();
var light, object, object2, materials;
scene.add( new THREE.AmbientLight( 0x404040 ) );
light = new THREE.DirectionalLight( 0xffffff );
light.position.set( 0, 1, 0 );
scene.add( light );
var map = THREE.ImageUtils.loadTexture( 'textures/ash_uvgrid01.jpg' );
map.wrapS = map.wrapT = THREE.RepeatWrapping;
map.anisotropy = 16;
materials = [
new THREE.MeshLambertMaterial( { ambient: 0xbbbbbb, map: map } ),
new THREE.MeshBasicMaterial( { color: 0x242424, wireframe: true, transparent: false, opacity: 0.1 } )
];
// random convex
points = [];
for ( var i = 0; i < 15; i ++ ) {
points.push( randomPointInSphere( 50 ) );
}
object = THREE.SceneUtils.createMultiMaterialObject( new THREE.ConvexGeometry( points ), materials );
object.position.set( -250, 0, 200 );
scene.add( object );
objects.push( object );
object.callback = function() { console.log('blabla');}
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( window.innerWidth, window.innerHeight );
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, window.innerHeight );
}
function randomPointInSphere( radius ) {
return new THREE.Vector3(
( Math.random() - 0.5 ) * 1 * radius,
( Math.random() - 0.5 ) * 1 * radius,
( Math.random() - 0.5 ) * 1 * radius
);
}
function animate() {
requestAnimationFrame( animate );
render();
stats.update();
}
function render() {
var timer = Date.now() * 0.0001;
camera.position.x = Math.cos( timer ) * 800;
camera.position.z = Math.sin( timer ) * 800;
camera.lookAt( scene.position );
for ( var i = 0, l = scene.children.length; i < l; i ++ ) {
var object = scene.children[ i ];
object.rotation.x = timer * 5;
object.rotation.y = timer * 2.5;
}
renderer.render( scene, camera );
}
function addMeteor()
{
var map = THREE.ImageUtils.loadTexture( 'textures/ash_uvgrid01.jpg' );
map.wrapS = map.wrapT = THREE.RepeatWrapping;
map.anisotropy = 16;
var materials = [
new THREE.MeshLambertMaterial( { ambient: 0xbbbbbb, map: map } ),
new THREE.MeshBasicMaterial( { color: 0x242424, wireframe: true, transparent: false, opacity: 0.1 } )
];
objects.push( materials );
var object3;
var points3 = [];
for ( var i = 0; i < 10; i ++ ) {

}

object3.position.set( -50, Math.floor((Math.random()*window.innerWidth)), Math.floor((Math.random()* window.innerHeight)) );
scene.add( object3 );
objects.push( object3 );
}
projector = new THREE.Projector();
// listeners
document.addEventListener( 'mousedown', onDocumentMouseDown, false)
// keyboard handler
function onDocumentMouseDown( event ) {
event.preventDefault();
console.log('blabla');
var vector = new THREE.Vector3(
( event.clientX / window.innerWidth ) * 2 - 1,
- ( event.clientY / window.innerHeight ) * 2 + 1,
0.5 );
projector.unprojectVector( vector, camera );
var ray = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );
console.log(objects);
var intersects = ray.intersectObjects( objects );
console.log(intersects);
if ( intersects.length > 0 ) {
intersects[0].object.callback();
console.log('blabla');
}
}
renderer.render( scene, camera );
I was supposed to push Mesh into Objects array, but which one?

THREE.SceneUtils.createMultiMaterialObject() creates an object with two child meshes.
So, you need to set the recursive flag to true when calling Raycaster.intersectObjects().
var intersects = ray.intersectObjects( objects, true );
