With MeshBasicMaterial, everything works fine. However, when I change it into MeshLambertMaterial, it's absolutely dark. Note that I have already set an ambient and a point light up and a Box just near the Obj model (everything is right in the camera) with MeshPhongMaterial shows up as expected. Also, to avoid setting normals the wrong way, I also assigned the \"side\" property of the material to DoubleSide as follows:\r\n```javascript\r\nvar material = new THREE.MeshLambertMaterial({color: 'yellow', side: THREE.DoubleSide});\r\n```\r\nFurthermore, I tried removing the normals in the OBJ and exporting yet another OBJ file to see whether it would work, only to find that everything remains the same."}}
