Lighting an Interior Daytime Scene - Photographic Rendering with V-Ray for SketchUp - page 51

With the Shadow Settings dialog box open, left-click on the show/hide shadows
toggle in the upper-left corner of the dialogue box to see how the direct sunlight will
fall in the scene. Then, if we grab the time slider and gently drag it left and right, we
should see circles of direct sunlight in the SketchUp viewport traveling across the
walls.
Now, from a purely compositional point of view, I would like to have those circles fall
on the floor somewhere just in front of the camera, but making this happen is not as
easy as it may sound. However, let's give it a go by altering the time sliders value,
setting it to read 11:20 AM . Then, we can move the date slider so that it is set to July
18. (Be sure to leave the time zone set at the default of UTC-07:00 .) This should
achieve the desired effect, creating three circles of sunlight on the floor in front of the
camera as shown in the following screenshot. So far so good.
Let's switch over to the POV Shot - Empty Room scene tab now and see if what we
are getting from this view will also work for us.
Unfortunately, as you can see, we have no direct light entering this room with our
current time and date settings. Even more unfortunate is the fact that even if we alter
our time and date, in this instance to 6:50 AM on July 8, the best we can manage
