All language subtitles for 06 - Add lights and change their colors in Blender

- [Instructor] Now that we've had a really fun time

changing the materials

and adding a bunch of them to our scene,

let's go ahead and add some lights.

First, you're going to want to

come all the way up to the top right

and click on Viewport Shading.

If, for some reason, things look really grainy,

click on the Render Property button.

Looks like the backside of a DSLR,

and scroll up and make sure that

you're using the EEVEE render engine.

Don't worry about cycles.

We'll come back to it a little bit later on in this course.

Right away, you can see that there's a light.

It's right here, and you can go ahead and move it.

It's not particularly interesting,

so go ahead and left click on Add

and come down to Light,

and you'll see there's a whole bunch of options,

like a sun light.

Sunlight doesn't care where you've actually moved it.

It just cares about rotation.

Another light that is really handy is spot.

Spot is a little bit like a sun light,

only it's a bit weaker.

As you can see here, I'm hardly getting anything on here.

Let's go ahead and rotate it

and then move it over,

and this is one of the challenges with spot.

It's kind of neat, but you have to click on

the lighting data down here at the bottom,

and where it says power, just, like, really crank it up.

One cool thing too is you can change the color.

I'll go ahead and make it yellowy,

or maybe actually a bit more bluey.

That way, it'll stand out,

but you really got to crank up the power

to really appreciate anything going on,

and even then, not too much.

There you go.

You can kind of make out what's happening here.

Another light that I love and use quite a bit

is the area light.

Why do I love the area light?

When you're using cycles, it renders very quickly.

It's got a lot of power right away.

You can see how it's quickly changing my scene here.

So I'll just go to, like, kind of a pink.

You can see, at a power of 100,

I'm already affecting a lot of things quickly,

and I can even change the shape

into more of a disc shape if I wanted to.

Most lights have the ability to change their size,

but be careful.

The bigger a light is, the less power it's going to have.

So just keep that in mind.

There's only so much power per square meter here,

so if I had a very tiny little surface,

I'd have a very powerful light.

Let's go ahead and click on Add, Mesh, Plane,

and it's really hard to see,

so you can click on scale over here

and just go ahead and scale it.

To do so, put your mouse right around that middle circle,

left click, and drag it.

Now, the middle circle is a little hard to see,

so if you can't see it for any reason,

you can also hit the N button on your keyboard,

N for numbers,

and you can see here, I scaled it to size of 42.

You can actually left click and drag these down,

and then type in 50.

So, left click, drag my mouse down, type in 50.

There we go.

I can either move this in here

or I can hit the N key to hide that again.

Really useful little menu.

I mentioned it before,

and you're going to go ahead and poke at it

every once in a while.

So, good shortcut to know, N.

Now that I have a floor, I can really start to appreciate

some of the lighting of what's going on here,

and you can see how shadowing

is really getting quickly affected.

Most lights inside of EEVEE

also have some shadow properties.

I'll allow you to play with them

and give you some extra little tricks that you can use.

While we're at it,

if you go up to the Camera Properties tab,

you'll see some tools that are quite useful here,

such as ambient occlusion,

which can give you a little bit more of an edge,

especially inside of EEVEE.

Let's come back to our lighting data.

I'm going to go ahead and click on my sun,

and I can see that I don't have too many properties here,

and it has a strength of one,

but remember that is the strength of the sun.

So you can get some kind of cool lighting effects

depending on what you want to do,

and change the angle if you want something really soft

or if you want something really hard.

All right, so now that you have

a good familiarity with lighting,

go ahead and add some more lights

and see what interesting scenes you can come up with.
