Photoworks Question

I will hope that someone who is skilled in Photoworks will tell me how I can achieve a shiny reflective background, or maybe floor in a Photoworks rendering. I have selected a green colored background color all right, but I much prefer that it be shiny and mirror-like. Please advise me as to what parameters I should follow and use. I am using Solidworks 2006 Professional. I do have access to v 2007 Premium if need be. Thanks in advance: Amy
