No problem making the prop (I created a simple mask)...but I want to use it as a single piece. Everytime I attempt a view from the back of the object, it disappears. Is there any way to give it more substance...either in Poser or Bryce or 3D Studio Max?

Go to the utilities section and download Twoface by Maz. It creates normals on the reverse side of props. Use it on hair props also to prevent seeing through the inside of long hair when viewing from the front.
