Uh... I think you are asking for something that can't be done. when a rendering program renders glass or transparent objects, it uses lights to calc the reflections, refractions and so on. So just simply cutting and pasting will not produce the look I think you are after. If I understand what I think you are asking. Poser does not suport reflections or refractions. You might have to do your rendering in Bryce. or if you have another render app. Here is a render sample of what I am talking about. Note how the glass refracts the background.

You can't call it work if you love it... Zen Tambour
