Three.js Repeat texture fail

问题

I'm trying to make a simple floor texture, but it seems that wrapS and wrapT don't works.

Look at the result: http://hpics.li/321350c

var texture = THREE.ImageUtils.loadTexture( "Game/Texture/drytext.png" );
texture.wrapS = THREE.RepeatWrapping;
texture.wrapT = THREE.RepeatWrapping;
texture.repeat.set( 4, 4 );
var floorMaterial = new THREE.MeshBasicMaterial( { map: texture, side: THREE.DoubleSide });
var floorGeometry = new THREE.PlaneGeometry(20, 20, 10, 10);
var floor = new THREE.Mesh(floorGeometry, floorMaterial);
floor.rotation.x = -Math.PI / 2;
scene.add(floor);

Thank you
