can't you make a negative boolean of a high cube so you can have that divinding line? as for frosting, just give the glass a default bump of some sort.

..... How can I put this..... my biggest problem isn't technical.... it's just that I don't recall ever seeing the kind of window I'm trying to create. I really don't know how wooden windows are constructed, so I don't know whether to put something between the two sides, or what? All the windows here are..... welll, odd. Like all the rest of the architecture... And I really don't know what kind of bump to use!

If you construct one side of the window frame and cut a 45 degree bevel using booleans, then duplicate it and position it by hand against the other side, you are sure to have a small gap. If I am envisaging the kind of window you are making right, the frames should just butt against eachother with no divider. Giving a standard glass a bump, white diffuse value and a touch of white ambience can make an OK frosted glass look.

i hate windows too...but i can't anything that might help, im new to bryce

i hate macs as they atract snobs :P

I make, design, and sell windows. For NW Exteriors. And I hate them with a deep, intense passion! But honestly, I'm not sure I follow what the problem is here? Is it material based?

There has to be something in the middle so you can lock the window....you've got quite a challenge here ;-)

I own a wholesale window and door distributorship which I inherited from my grandparents last summer.... which is why I haven't been around much since then... and I must admit that I'm having trouble following what you're trying to do, too. Actually, what it looks like you've got going is what we call a French door, two doors hinged at the jambs (sides) and locking together in the center. If this is the case, then in your image the corners of these doors (or window sashes) are touching while the doors themselves are at a right angle to each other (judging by the position of the knobs). I'd have to say, based on what I can see in your image, is simply to make each "side" of your window separately. Place the two sides together as if the window were closed. Then rotate eace "side" at the point where the hinges would be (can you move an objects "hot point" in Bryce?) to open them. Also, there would be some sort of projection on one of the "sides" which would overlap the outside of the opposite "side" when closed to prevent weather from getting in. Hope this helped some.

BTW... very nice plates you've got around the knobs

This has been some really great info, guys! Sorry to be so vague, but I really don't know what I'm aiming for at all. This is just an attempt to recreate the view from the window in Harfang in the Silver Chair by C.S. Lewis. The bump idea is cool, but would that make the frost patterns too? Hehe, just realized I don't exactly live in a place where you would see that, either.
