Good morning j meyer.
I think you mean the same as I saw? : eg. at the window frames the shadows and sunbeams seam to stop.
Until now it's a mystery to me, why the glass shader of the windows prevents sunlight to cause shadows.
If you eg. look closely to the guitar-head you can see that I managed to get slight shadows on the wall but they seem only to be from the general ambient lighting.
I didn't find out until now, how to get the sunlight "through the windows"
If it's an issue of the glass shader perhaps one of the next TG3 updates will help.
Yesterday evening I played with the clock... I didn't like the clock face.
So on the basis of the original clock I recreated a "new" clock in Wings3D.
I deleted the 12 numbers and the 60 subdivision dashes - they were each a single object.
I also deleted the clockface because I couldn't get a UV-mapping on it and inserted the round carpet.
So now what you see is not a clock face but a carpet inside the clock glass
Hope you can friendly smile about my solution

Only postwork was a little brightening and increasing gamma and contrast.
Update 11:15
An experiment: I increased the tranparency to 100 but the effect is the same: Sunbeams and shadows seem to stop at the windows...
