Mirror question

[natalia]

Hello
I am curious how I can apply addMirror function, or better, how should I modify the script that I have found in WorldViz Knowledge Base called "Adding a Mirror", if I need to create other "mirrors" opposite the first one, and also two mirror glasses perpendicular to it. Actually, I have to make windows of metro carriage transparent and reflecting. I can't understand which parameters I have to change, what influences on the distance of clip plane and other distances, and how to manage it.
I would be thankful for any advice!
