I'm using camera attached to head template also added this camera inside a rig and that rig is constrained to nav-mesh but only one is working either movement control of rig or wasd control of camera and not both.

<a-entity id="player-rig" movement-controls="constrainToNavMesh" >
    <a-entity
      id="player"
      networked="template:#avatar-template;attachTemplateToLocal:false;"
      camera="active:true;"
      wasd-controls="acceleration:12;"
      position="0 3.5 0"
      look-controls>
     </a-entity>
 </a-entity>

If there is any good way to use these both and if it works .Let me know
