Smooth shading not working for OBJ loaded in Three.js scene

That is, the OBJ looks smooth in my 3D modeling software while looks quirky (triangular) in Three.js scene. I assign MeshLambertMaterial to it. According to the documentation, the default shading for that material is THREE.SmoothShading. Even if I set it manually and check through the debugging console the "shading" property is properly set, the model in the scene still does not look smooth.

The VertexNormals are not calculated by the OBJ(MTL)Loader. You can calculate them afterwards (haven't tested):

my3dObject.traverse( function( node ) {
    if ( node instanceof THREE.Mesh ) {
        node.geometry.computeVertexNormals(); 
    }
} );
