Implementation

    }
  }

  // .extras has user-defined data, so check that .extras.targetNames is an array.
  if (meshDef["extras"] != null && meshDef["extras"]["targetNames"] is List) {
    var targetNames = meshDef["extras"]["targetNames"];

    if (mesh.morphTargetInfluences.length == targetNames.length) {
