Quote - Well, I've come to the conclusion that it is virtually impossible to have glass reflection. Not without trickery, anyway :)
I thought you did a render a long time ago of a reflection in the eyeball (wasn't that possible because it was set to glass?)
Have you set up a test with your flattened cube, ensure no light can get behind it at all. Put a sphere in front of it and light the sphere, (either as the light source, or light it with a mesh pointing at the sphere and away from the glass pane). You should see it reflected? If that works, then it is just a case of balancing the light 'outside' the window pane to the light on the objects on the inside of the pane? I'll do a test when I get home this evening to see if you like?
the reflection of the light can be seen in the glass objects in Xandi's image above, so the glass is certainly reflective... You could set up the positions by first setting the glass to be mirror, to ensure the items are lined up correctly for the camera position etc...
someone on the old daz forum posted images of 'peppers ghost' that was done using the glass method, of which I also had a go at... Unfortunatly I'm not at home, otherwise I'd look up who it was! `¬)
...also see this image, the ende of the cabinet are glass and you can see a double reflection in each surface....
