[away3d] Changing Flash Quality on the fly?

[MarkC]

Not directly releated to Away3D, but can anyone give me a pointer.

If I set the stage quality during my initialisation it works fine.
What I want to do is change it once the Flash is up and running. I
created a public property and expsoed this via an External Interface.
But when I call it, nothing happens. From what I have read you should
be able to change the playback quality on the fly?

public function setLowQuality(qual:Boolean):void {
  if (qual)
    stage.quality = StageQuality.LOW;
  else
    stage.quality = StageQuality.BEST;
}


Thanks
Mark
