I am using THREE.ImageUtils to load maps and bumpmaps.The grayscale image of the maps are used as bumpmaps .on adding bump maps it doesnt gives any effect on it.
var material = new THREE.MeshLambertMaterial({ side: THREE.DoubleSide });
material.map = THREE.ImageUtils.loadTexture('http://i.imgur.com/ZjBRB2d.jpg');
material.bumpMap = THREE.ImageUtils.loadTexture('http://i.imgur.com/tz483el.jpg');
Is Repeat Wrapping of bumpmaps are possible as maps ?
