'and set the shadow maps so that you get nice crisp shadows' That means set Map Size to 1024, and Shadow to 1.000. A value of 1.00 will give hard shadows. Set it to .500 or right down to .100 for softer shadows. Of course, you still need a window frame.... At the worst, you could make the shape with a set of scaled poser box props and bung it in front of the light. mac
