Good afternoon to everyone,

I have a small problem with windows and transparency of glass. When I start rendering, through the window I can´t see other window behind this one (it is shown in attached picture) and sometimes it is making strange stains on wall or floor.

I don´t know if I have bad setting on glass or on windows, so I don´t know how to fix it.

If you know how to help me, I would be very thankful.

Have a nice day.

this is the problem
