  <pre><code>        loader.load( "../models/islands/"+islandselected.getAttribute("data-model")+".dae", function(object){
          scene.remove("island");
          plane=object.scene;
          plane.name=islandselected.innerHTML;
  
          plane.traverse(function(child){
              if(child.children[0]){
                  if(child.children[0].geometry){
                      console.log(child)
                      var t = new THREE.ImageUtils.loadTexture( '../models/islands/'+child.name+'.jpg' );
                      t.wrapS = t.wrapT = THREE.RepeatWrapping;
                      t.repeat.set( 50, 50 );
                      var ma= new THREE.MeshBasicMaterial( {map:t} );
                      child.children[0].material=ma
                  }
              }
          });
          plane.scale.set(100,100,100);
  
          scene.add(plane);
      });
