What determine visibility of model-item? - HoloLens

[nqwifly]

I'm planning to include a hide feature in my experience, giving the user the ability to hide a model to perform certain instructions. Showing the model all the time will block user's sight.

I managed to make the whole model invisible using this code

  for (i = 0; i <= length; i++) {
      modelitem="model-1-/0/"+i;
      tml3dRenderer.setProperties(modelitem, { hidden:true } ); 
    }

However, even though the property 'hidden' set to 'true'. When animation started some of the animated parts will be shown. Not all the parts! which makes me wondering why? how to prevent it from showing, or at least how possibly show all the animated parts? I'm stuck in between.

Thanks for the help in advance.

you should hide the necessary items as part of the instruction sequence (in illustrate)

this is the correct way to approach this.

the sequence author typically has a much better idea of what is needed.
