title: Change GameObject materials back to Original ones
body: <p>I'm trying to make a stone skill effect on a gameObject (a skeleton with a spear) changing its materials to a stone one and then changing back to previous ones.</p>
  
  <p>What I'm interested in is the change back. 
  The gameObject has some childs and childs of childs.
  On some of these childs the are renderers.
  Some of these renderers have more than one material attached.</p>
  
  <p>What I ask for is a code to save the materials attached to these renderers and a code to set them again after the stone effect ends....or something similar.</p>
  
  <p>I tried many times but I didn't obtain a complete result.</p>
  
  <p>Thanks.</p>
