I created a function that made my plane and text mesh (merged) always face to the screen. But what I found that is they always return to position 0,0,0. Any suggestion ?
lookAtMe(modelBuilder, dbId) {
this.objects[dbId].matrix.makeRotationFromQuaternion(
this.viewer.getCamera().clone().quaternion
);
modelBuilder.updateMesh(this.objects[dbId]);
