title: Shader vs Shader Material , papervision specific , general insight welcome
body: <p>I asked this question on the pv3d forum and not a single person could, or cared to answer it.</p>
  
  <p>Im relatively new to 3d so i apologize if this is common sense to some. </p>
  
  <p>I have a sphere , in which i am applying a CellMaterial to. Looks great. 
  I noticed that in the papervision sdk , there is also a CellShader. </p>
  
  <p>Should I be using this in congruence with the CellMaterial ? 
  Should it be one or the other ? 
  Is shader , a deprecated practice to Shader Material ? </p>
  
  <p>My initial thoughts were that the shader applies to the whole scene , while materials can be applied uniquely to objects. </p>
  
  <p>The documentation seems to show otherwise. </p>
  
  <p>What benefit if any could be gained by using both a CellShader and a CellMaterial ? id really love to get some ambient inclusion in there some how.</p>
