The best way to do it would be like this. Open the window in uv mapper. Select Planar Map / Alignment = Z-axis / Split = By Orientation. This will give you a map of the 2 faces of your window, front and back. Now what you have to do is select one of the 2 parts of the map and assign a new material to it. You do this by going to Menu> Tools> Assign to> Material. If your window already has a material, like 'window', you can just select one part and call it 'inner', then select the other and call it 'outer'. Save the obj then re-import it into poser. It now has 2 materials, inner and outer. Now you can put a different reflection map on each side of the window. Like a sunset (or whatever) on the outer, and a room on the inner. Oh, and set the Object Colors for both materials to something fairly dark. mac
