      i still think there is something strange going on in the podium daylight renders (both yours and mine) - shouldn't all of the room boxes be equally lit? some of the ones in the center of yours are obviously darker which doesn't make much sense unless the light source is very close to the model.

      edit: i notice the same thing happening in solo's post as well - check out the bottom box

        Good call, that's exactly what the problem is with mine. I created a huge emitter plane and placed it in front of the "building". It's not that far behind the camera. So I was getting daylight bleeding around the edges of my emitter which made the boxes around the perimeter brighter. I noticed the same thing but couldn't figure it out until you brought it up. I should have turned by big box enclosure on for the "day" rendering too so I wasn't getting any sunlight, only the light from my emitter. That should have evened it out.

        You can open up the SU model to see what I'm talking about.

          ah - thanks for posting the model. I gave it a shot with the big box trick and the lighting was much more even - good fix!

              So is there a way to turn off the sun altogether in podium? I guess I was assuming there must be but I'm surprised no one has chimed in on that.

                you do not do that in podium. the beauty of it is that you do almost everything in SUp. for a night scene in podium you turn off the sun in SUp and give the background a dark color.

                  ahh, maybe the background was my fatal flaw. By turning off the sun you're saying just turn off SU shadows? I did that but it was still pretty well lit, I didn't change the background though so maybe that's the trick.
