Hi everyone,
As I was trying to investigate the reasons of ambient shadow inconsistency that troubled me for a while, I noticed an interesting issue. As you see in the attached images, I have a simple scene with ambient shadows only. I duplicated the same view (with detailing) 4 times with the same lighting and display parameters, and as you see, the ambient shadow's angle and intensity are different on the same page. But this is not the weirdest thig! It gets even more interesting when I start moving one of the views on the same sheet. In each position, the shadows are different. So, it seems that revit has an internal source of ambient light in the center of the page that affects the views differently in each position, no matter what your lighting parameters are!
Does anyone have any ideas about this issue?
