Cycles - glass: how to eliminate shadows

Hi all!

I’ve got this situation: a house with lots of windows. I need the windows frame to cast their shadows inside the house, but that doesn’t happen.

This is the preview without glass (correct shadows of the window frame).

And this is with the glass shader on.

Suggestions? Work arounds?

Blender 2.76b, transparent shadows on, sampling 20 of everything.


Ok, after a little fiddling with Cycles I’ve found that i need a workaround.

Any suggestion (or link to valid workaround) will be really appreciated :smiley: :smiley:
