I maked a room with a hole (for window) and a glass (a transparent cube). I have a exterior lamp.
The problem is the light dont cross through my glass-window!
(If I remove the glass, I have light in the room.)
I pressed ray tracing for render, and light, and I enable Ray Transp for the glass.
And when I loaded a default glass mat from library, nothing happend!
Please, help me, what should I do?
