Accurate Window Reflections

[Anonymous]

Hi there everyone,

I am trying to recreate the effect you see in windows where the light bounces back between the double-glazed window and creates this effect where the light seems to fade away the further it gets away from the light source.
I have tried playing around with the settings on the glass but I can't seem to get the effect going. When I try to tweak the values all the reflections of light fade simultaneously.

Thank you for your time

Can't you just apply less reflective shader to the outer glass. If you need "the infinite reflections", then make more glass planes with even less reflectivity, and, perhaps, leave just specular output.
