Here we are in Poser 7:

1.) Here is a simple scene with just a High Resolution Plane, in Wireframe mode/view.

2.) Render the scene and this is what you see.

3.) Here we are in the Poser Material Room, having applied a Transparency.

4.) Render, now with the transparency applied, and this is what is seen.

5.) But if you leave the Render Window; and go to the Preview Window, and you still see this, because the "Transparency is really just a Render Engine Trick, that just hides some of the Plane's vertexs(During the render process)

6.) Rather than have the Render Engine Hide some Vertexs; I'd like the program actually delete the "Hiden" vertexs from the Plane, and  leave an image like this, in the Preview window.
