Hi md,

Try using the Grouping Tool (in Poser) to:

Make a separate group for the window(s). (whether it be a polygon or polygons)

Then "Assign Material" to that group.

Now you can control that group's (that is, the window's) color, ambient color, transparency, etc. separately without the need for any transparency maps..
