- [Instructor] Now, let's save a few scenes
representing the sunlight and shadow
at different times of year,
specifically, let's examine the solstices,
both in the morning and in the afternoon.
Let's zoom in over here on this block
where we have this staircase,
and then let's open up the Shadows window
and toggle on shadow casting up here.
Let's first examine what it looks like
during summer solstice,
so that would be on June 21st.
What would it look like in the morning?
Let's see. I'll just drag this over
and you can see the shadows are moving.
Let's say that the cafe would open around 7 a.m.,
so we want to capture this moment.
Let's now go up to Window, Scenes,
and if I try to save a scene,
we get this warning,
and this is happening because there's a style issue,
so let's cancel
and open up Styles as well.
Right now, you'll see this arrow icon
superimposed over the style icon,
and if you click this symbol,
it will update the style with the changes.
Once that's done, you can save a scene
and you don't get the warning.
Now, I'll go over here and say
"Summer
Morning,"
Enter, and that updates the title.
Now, let's change the time of day
'til around 4 p.m., and then we'll create a new scene,
and I will give that the name "Summer
Afternoon,"
Enter.
Let's also examine the situation
during winter solstice,
so I'll change the date slider to be
the 21st of December,
and let's start at
7 a.m. or so.
It's completely dark then. No surprise.
We're going to have to start a little bit later.
Let's say it's
7:30.
Okay, now I will save the scene
and rename that "Winter
Morning,"
and then again, in the afternoon,
Let's see what the shadows look like at 4 p.m.
4 p.m.'s pretty late in the winter,
but we'll set it to 4 p.m.
Save the scene.
"Winter Afternoon."
You can now toggle between these scenes,
and you'll see the sunlight change.
You can also control the speed
at which the shadows transition
by going into Model Info
under Animation, and you want to change that here.
If you want it to be a little slower,
maybe it takes three seconds.
You also need to make sure that this is checked,
and if it's unchecked, there will be no transition.
It will just go directly to the next scene,
so now, I can have a little bit of a slower transition
from the Summer Morning
to the Summer Afternoon.
In the next video, we'll examine the sunlight
in the context of these four different cafe locations
highlighted in blue,
and we'll come to some conclusions
about which might be the most auspicious site
in terms of solar exposure.
