I am currently using THREE.ImageUtils to load maps and bump maps. The grayscale image of the maps is utilized as bump maps. However, when adding bump maps, no visible effect is observed.
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');
Can bump maps be set to repeat wrapping like maps?
Unfortunately, MeshLambertMaterial does not support bump maps. You may want to consider using MeshPhongMaterial or MeshStandardMaterial instead.It's worth noting that bump maps do support repeat wrapping, but it's important to ensure that if you have a diffuse map as well, both the map and bump map must have the same repeat setting. More information on this can be found in this answer.
While this limitation exists in the current version, there is a possibility that it may be changed in a future release.
Current version: three.js r.77
