Isn't that what a matte is for in a compositor? An easy way to do that in Softimage is to unplug the 'surface' port of the material on the polygon. Mental ray will render the affected pixels as RGBA = (0,0,0,0).

Soooo...... Can Soft create xray polygons? A material maybe? The idea is that I want to have a polygon render invisible but everything behind it render invisible(with no alpha) as well. Basically a mask poly. Maya had the ability to do this but can't remember what it was called. In other applications it was xray, allowed you to see through things.
