All language subtitles for 613241-58 - Shadows - The definitive SKETCHUP course. From beginner to expert.en-US

Hello people and welcome
to this new class in

where we're going to
see the saddles trip.

It is already expanded
and we have as well

a toolbar called
Show Hide settles.

Here.

We have the main options,

but if we move to
the tray shadows,

as you can see, we'll find
here many more options.

So let's start from
the beginning.

We have this button,
so hide shadows.

It is the same as this one.

So if I hit,

then I am switching on the sun.

In a sketch, we have now

these cast shadows on

the ground and thanks
to these, sliders,

will be able to adjust

time and the day
and a specific day,

which will change the
position of the sun

and then it will make change
as well, the cast shadows.

So e.g. if my time is 12:00,

I mean, it is known and
we change the month,

moving the slider to
our summer months,

not a winter month,

the cast shadows
will be very short

as it happens in
our normal life.

On the contrary, if we are
still using the same time,

12:00, but our month
is, let's say e.g.

November, the cast shadows

will be much more longer, right?

We have to control
these settings in

order to make the
best of our project.

Anyways, we have
here more oxygens.

It is the light.

Now we're not talking
about the cast shadows.

We are talking about the light.

So we can make that
light lighter here, e.g.

or we can make that
light more bright.

The next slider is
talking about this time,

years, about the cast shadows.

We can make them
lighter or darker.

This another option
called use sun for

saving makes sense
if this button,

the first one, so hide
Santos is turned off.

So let's do it.

We don't have cached
silos anymore,

but we are still using
the SketchUp some

because this oxygen is
already marked, right?

That means that we
have some faces

illuminated while
others are not, right.

E.g. this one, the
difference is that

we are not using cast shadows,

but we are still using the
position of the SketchUp son.

If I unclick this
option we have is still

an artificial light because
some faces are eliminated,

but not all of them with
the same intensity.

But right now, as we are
not using this upsilon,

that artificial light
has nothing to do

with the SketchUp sun and
then with this slider.

So this option, in my opinion,

it is not very useful
and important.

Anyways, we can mark it.

Let's turn on so high shadows.

Let's check these other
options on faces,

on ground from edges.

To understand
better this option,

I will draw here a cylinder.

Then we will see
how we have cast

shadows on the faces
of this cylinder.

If I turn off on faces,

then you can see how

our cast shadows is not

affecting the phases
of the ceiling.

So to be more realistic,

I recommend you to use this
option on faces on ground,

as you can imagine already,

is going to allow us to
cast shadows on the ground.

If I turn off this option,

we don't have Saddles
anymore on the ground,

but pay attention here
because it can seem

obvious that we will need to use

all the time this
on ground epsilon,

but it will depend
on its case, e.g.

if I have this kind of situation

in where I have a
hole like this one,

Let's draw it and
then I turn on,

on ground, I will move.

Don't read the data slider.

And the time, you can
see that here we can

find a kind of error, right?

Because this cast shadow from

the queue on the
ground is turned on,

is going through the whole
plane as a horizontal plane,

and it is not going
inside the hole,

is not working in a
realistic way, right?

So how we can resolve
this problem?

First of all, we have
to turn off on ground,

then we have lost the cast
shadows on the ground.

Obviously, in that case,

we will need to create
our own ground.

So I will select this x

and I will make this
phase much more bigger.

I will reverse phases.

And then if I move the sliders,

now, I don't have
that problem, right?

My cast shadows are
working in a normal way.

We're not creating
that horizontal plane.

I will turn on,

again on ground as it
happens here, right?

So on round is not

always an option that we
have to mark here, e.g.

it is better to create

our own ground and
unclick this option.

Finally from this will allow us

to make cast shadows
from an egg.

Individual ads, e.g. I.

Will draw here a vertical.

Now this is not
making any shadows,

but if I click from edges,

you can see that
now we have this x.

Let's jump now to
these projects.

A Greek temple, and let's
use the subtle Stray here.

First of all, we have
to turn on the shadows.

Here they are.

And now through these sliders,

we will control the position
of our cast shadows.

E.g. here could be okay.

We will use this example for

explaining another
important tool.

When we are working in
a project like that,

maybe we want some
elements to have

an specific behavior in

terms of cellulose,
e.g. the roof.

Sometimes maybe we don't want to

cast shadows or to
receive shadows.

If we want one element to
behave in a specific manner,

we have to select it,

go over Entity Info,

and then we have
these two options.

One is called Dawn
receive shadows,

and the other one is
called Don't cast shadows.

So e.g. this roof,

it is already selected.

If I hit, don't receive shadows,

it will not change
now because we don't

have any cast shadows on it.

We have just the
light of the sun.

But if we hit,

Don't cast shadows, then
it will change a lot.

What is happening inside

the building because
this element,

this roof, is not
casting shadows anymore.

We could do the same with this.

Another roof don't cast
shadows and then create

inside the building
another effect

with more and more light.

Of course we are,

Let's say that we are cheating
a little bit or a lot.

But sometimes could
be very useful in

order to put some
more light inside

our interior and
being able to tell

our client or whoever

our ideas in a better
way in a sketch.

My last advice here is
that you have to be

aware that when we are using
the saddles in SketchUp,

we're consuming a lot of
resources of our computer.

So just turn them on
when you really need it.

The rest of the time
when you are working,

just modelling, my advice
is to turn those off.

So we finished the episode here,

and I will see you in the next

one in where we will continue

modelling our Barcelona
Pavilion using our new skills.
