I have a question:
it is normal that the sunlight does not pass through glass?
I add a picture showing how the sun does not creates shadows-lights inside the building...
I use pathtracing kernel...
Thank's

Yes, at moment only hdr or meshlights.
You could fake it with a glossy material, rougness to zero, specular up and opacity to 0.5.
Cheers, mib.

hi mib
I try to do what you say but the result is bad
1) whit hdri ther's not sun into my object, there's not shadows in all render!
2) whit glossy material the glass is not clear but is white
Where i wrong if i wrong??
Is a big problem for exterior renders!!

This is a weak point of the kernel.
I had the same problem:

I am not using the "flipped normal trick" with the glossy. I simply use the specular but decrease the oppacity to 0.1 or 0.2.
The new version 2.5 with the kernel will probably solve this issue.
