light through glass - help please

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! :frowning:

Please, help me, what should I do?

Thanks,
Cristi

in materials for the mesh that is recieving the transparent shadow, press ‘trashad’. that should work. if it doesn’t come back and we’ll try something else.

A very big thanks!!! It works!!! :smiley:
