Animating a THREE.Points object - three.js

Question

I'm trying to load a model from Blender, apply a PointsMaterial to it and animate it. So far, I've been able to load the model and animate it successfully as long as I use a material other than THREE.PointsMaterial to create the mesh.
When I create a THREE.Points object, the animation doesn't play. I noticed that when I set the PointsMaterial's morphTargets property to true, there's a warning saying that there is no such property of PointsMaterial. Does Threejs not support animation of Points objects using morph targets?
monster refers to a mesh that works when animated. It uses the loaded geometry and material. ParticleSystem is the the THREE.Points object.
Code:
function loadObject(path){
var loader = new THREE.JSONLoader();
loader.load(
path,
function(geometry, materials){
var material = materials[ 0 ];
material.morphTargets = true;
material.color.setHex( 0xffaaaa );
monster = new THREE.Mesh( geometry, materials );
monster.position.set( 0, 0, 0 );
var s = .003;
monster.scale.set( s, s, s );
var particleMaterial = new THREE.PointsMaterial({
color: 0xffffff,
size: .005,
morphTargets: true
});
particleSystem = new THREE.Points(geometry, particleMaterial);
particleSystem.morphTargetInfluences = monster.morphTargetInfluences;
particleSystem.morphTargetDictionary = monster.morphTargetDictionary;
particleSystem.position.set(0, 0, 0);
particleSystem.scale.set(s, s, s);
particleSystem.matrixAutoUpdate = false;
particleSystem.updateMatrix();
particleSystem.geometry.verticesNeedUpdate = true;
scene.add(particleSystem);
mixer.clipAction( geometry.animations[ 0 ], particleSystem )
.setDuration( 5 ) // one second
.startAt( - Math.random() ) // random phase (already running)
.play(); // let's go
}
)
}
