Quote - > Quote - How do I get truly reflective glass? As I sit here (10pm), looking out of the window, the inside is reflected on the window, and I can see what is outside. In Reality, how can I do that?

The glass material will do it. Just don't use the Architectural flag. The best is to have a pane of glass that has thickness to scale.

The arch flag doesn't affect reflections, it just disables transmission refraction (thus also giving a transparent shadow instead of refraction caustics). This is pretty much exactly what it's for, actually. The thing you need to remember with window reflections is they mainly have to do with how bright the light is on the inside and outside of the window. If it's bright inside, the reflected light will overpower the transmitted light, making the glass look like a mirror. If it's bright outside, like a sunny day in a room with the lights off, the transmitted light dominates. So just make sure you have enough interior light. You can fudge it if you want by increasing the IOR (thus weakening the fresnel effect) or mixing in the mirror material, but neither one is physically correct, so try to do it with lightining and keep the ~1.5 IOR. (mixing in the mirror material might vaguely mimic how a one-way mirror is constructed. Which, btw, also relies primarily on having more light on the "mirror" side)
