      var layer = layers[i];
      if(layer.pbf){
        //construct the GeoJSONWrapper here, so that we can tell him the version !
        pbfOptions[layer.name] = new GeoJSONWrapper(layer.pbf.features);
        pbfOptions[layer.name].name = layer.name;
        pbfOptions[layer.name].version = 2;
      }
    }
    if(pbfOptions.length === 0) {
      return undefined;
    }
    // we use fromVectorTileJs instead of fromGeojsonVt because we constructed the GeoJSONWrapper ourselves
    var buff = vtpbf.fromVectorTileJs({layers: pbfOptions});
    if(buff) {
      buff = new Buffer(buff.buffer);
    }
    return buff;
  });
};
