Arcady, For windows I use this formula most of the time. Color:Value = 0 Highlight:Value = 90 Highlight:Value = 90 Reflection:Value = 10 Transparancy:Value = 90 This gives you reflections, highlights and allows you to see through it. The trick, as long as your close to 100% transparancy is to turn Cast Shadows off on whatever you are using for Glass. It's much faster than lighting through transparancy and in most cases people won't notice the difference.
