title: Three.Js Bump maps and UV Layout
body: <p>js Peeps</p>
  
  <p>I have an OBJ model with a UV map that is not rendering the bump map correctly.
  As you can see from the images the UV map checker texture shows a smooth flat surface. Unfortunately when the bump map is applied there appears to be tears across the bump map texture. (It is just a basic repeating texture which works fine for a different OBJ)</p>
  
  <p>Has anyone else experienced this effect?</p>
  
  <p>Many Thanks</p>

  <p>Here is the bump coffeescropt map code:</p>
  
  <pre><code>#BumpMap
  mapHeight = THREE.ImageUtils.loadTexture( "/images/3d/bump.jpg" )
  mapHeight.anisotropy = 4
  mapHeight.repeat.set( 0.998, 0.998 )
  mapHeight.offset.set( 0.001, 0.001 )
  mapHeight.wrapS = mapHeight.wrapT = THREE.RepeatWrapping
  mapHeight.format = THREE.RGBFormat
  </code></pre>
