My goal is to use a bump map on a plane in Three.js r55 to create a surface that resembles felt.
Here is the code I am using:
var mapHeight = THREE.ImageUtils.loadTexture("images/felt.png");
mapHeight.repeat.set(2, 2);
mapHeight.wrapS = mapHeight.wrapT = THREE.RepeatWrapping;
mapHeight.format = THREE.RGBFormat;
var groundMaterial = new THREE.MeshPhongMaterial({
ambient: 0x008800, color: 0x008800, specular: 0x888888,
shininess: 25, bumpMap: mapHeight, bumpScale: 10, metal: false
} );
scene.add(new THREE.Mesh(new THREE.PlaneGeometry(0.3, 0.3), groundMaterial));
I have set the texture to repeat along x and y axes twice. However, when I view the result, the texture only appears in one quadrant:
Even though I have used RepeatWrapping, it seems like the bump map is not repeating as expected. How can I ensure that the bump map repeats an arbitrary number of times on the plane?
EDIT - Full Code
To demonstrate the issue, I created a simple test case that reproduces the problem seen in the image below (slightly different camera angle). The output still exhibits the same problem.

requestAnimationFrame( function () {

bumpMapTexture.repeat.set( 2, 2 );
bumpMapTexture.wrapS = bumpMapTexture.wrapT = THREE.RepeatWrapping;
var groundMaterial = new THREE.MeshPhongMaterial( {

} );
scene.add( new THREE.Mesh( new THREE.PlaneGeometry( 3, 3 ), groundMaterial ) );
camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.01, 100000 );
camera.position.set( 0, 0, 3 );
camera.lookAt( new THREE.Vector3( 0, 0, 0 ) );
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( window.innerWidth, window.innerHeight );// renderer.render(scene, camera);
document.getElementById( 'scene-container' ).appendChild( renderer.domElement );
}

This code references Three.js r55 (minified).
Any assistance would be greatly appreciated.
