With my recent success of using the glass shader (finally) I dug out a couple models I made.
Beige is a SketchUp import to Blender, export as obj. (Made about a thousand years ago) (Seriously)
Gray vee Blender obj, is just a series of extrude, subdivide, etc. from a cube, trying different angles.
One window has Hannes' silver tgc for a mild reflection tyvm

Lights: a big thanks to Bobby Stahr's help
GI 1.5 Thanks Hannes!
