title: Papervision rendering PNGs with transparency thats inside a movieclip
body: <p>I'm an actionscript dude - I'm working on a papervision game.</p>
  
  <p>I have an asset of which is 127 pngs in a sequence for an animation.</p>
  
  <p>I can happily project this onto my papervision plane. Problem is, there is no transparency. I Can't use a BitmapFileMaterial as I have many pngs -</p>
  
  <p>can anyone suggest how to do this.</p>
  
  <p>Very very grateful -</p>
