Hello everyone and welcome to a new section.
This section is going to be a very fun because it is
focused on the lighting, our interior scene.
We're going to be adding in an HDR to our environments,
adding some lights everywhere,
some pool lights, exterior and interior lights,
and it will be covering all that in this video.
One thing I wanted to quickly mention is
that for this video in particular,
we're going to be using an HDR.
If you want to use this same HDR that I am using,
I got it from Pali haven.com.
This website is fantastic and they have
so many high-quality HDR is
textures and models, all for free.
I highly recommend checking this website out,
supporting them if you can't.
Another thing I wanted to say is that this course is
just a guide for you to create your own 3D house.
So go explore and find an HDR that you like.
If you want it to use the same one that I'm using,
it is in the resources or
in the article previous to this video.
So go ahead and grab that link or
explore this website and pick one of your own.
Once you have downloaded and HDR that you like,
we're going to go ahead and get started to add this in.
We need to go over to the world settings.
And then over in the color right here,
we're going to click that little yellow dot
and then select the environment texture.
We're not going to be using an image texture.
We're going to be using environment.
Environment means it's going to add
a 360 degree image all around the environment.
So let's go ahead and select it and then click on Open.
The HDR that we're gonna be using is this one right here.
And I do recommend testing out
some different HDR is because they
can give you some really interesting results
depending on which one you pick.
So once you've found it, select it,
and then click on Open Image
to actually see what this HDR looks like.
Let's press Z and go into a rendered view.
This might take a minute to calculate, but once it does,
you can see this is our HDR and we can move
around the scene and see everywhere just like that.
And that is looking pretty cool.
Let's position this HDR the way that we want.
Because at the moment,
when we place our camera right about this position,
I don't want there to be a tree
and a field in the background.
I want there to be sky.
So we're going to rotate the HDR to do this,
come up to the top corner and then split this window.
Once again.
We're going to switch this to
the shader editor just like that.
And then before you do anything else,
click on the object and switch it over to the world.
Nodes. Here is all
of the nodes that we're going to be changing
for our world rather than an actual material.
So first off with the Node Wrangler add-on enabled,
we can select the environment texture,
and press Control T to add an,
a mapping and a texture coordinate note,
make sure you are using
the generated texture and plugging it into the mapping.
And then if we take the Z rotation,
we can move the environment around.
So you can see if I rotate it up,
it's going to move it around.
So let's find a position where we
want our HDR to line up.
Now before we actually find
a position that Let's set where we want our camera to be.
So what I'm gonna do is place
my viewport right about this angle.
And now what we can do is a shortcut that allows
the camera to snap exactly to where we are looking.
So I'm going to place my view right about here or so.
And the shortcut is Control Alt and
numpad 0 to snap the camera to view.
If you don't want to press that way you can do
is come down to view over 2,
Align View and then click right
there aligned camera to active view.
You can also see the shortcut is Control Alt numpad 0.
Once you've done that, you're going to need to select
the camera by clicking in the bounding box,
you can press the G key on your keyboard,
middle mouse button, and drag
it back until you find the right spot.
So at this point you can play
around with the position of your camera.
You can also double-tap are and move
the camera up like this to get more of an angle,
you can drag it down,
do whatever you want.
You can rotate it along the z.
So if you hit R and Z,
you can rotate it like this.
So I'm probably going to go somewhere
around here and bring it
back because I want to see a bigger view of the house.
Rotate it this way,
just slightly, something like that.
And if you want a wider view,
you can also go over to the camera settings and
blender and you can see the focal length
is currently set to 100, 50.
If you go down further,
it's going to zoom out the camera.
So I think I'm actually going to go
down just a little bit probably,
let's go with a value of 40.
I think that's a pretty good focal length.
And then we'll zoom in slightly more,
something like that and place the camera there.
I want to be able to see the brick wall and I also
want to be able to see this side of the house.
So I think I'm happy with that result.
This gives us a nice view of
the grass and everywhere else.
Alright, now that we have our camera in place,
we can actually change the rotation
until we're happy with the result.
So we'll drag this back out and you can rotate the HDR.
So if you want more clouds or
less clouds, you can move it around.
I'm probably gonna go with somewhere around here.
I think I like that reflection along that wall.
So I think I might do something like that.
And probably around there is pretty good.
We've got some nice clouds in
the background and the lighting is pretty good.
Next, I'm also going to change the strength of
this HDR because at the moment the strength is too high.
What I want is for our scene
to have the look of the blue hour.
The blue hour is a time of day where the sun is going
down and the sky is a really vibrant blue.
So if we turn the strength down of our background,
let's try a value of about 0.1 or so.
It is going to be pretty dark.
But don't worry, once we add in some exterior lines,
interior lights, it's going to look really cool.
You can also, if you want to add more blue to your scene,
you can press Shift a at
an eight color and a hue saturation node.
You can place this here.
And if you bring up the saturation,
you're gonna see it gives us a more blue look,
which I actually like.
So I might drag it up just slightly.
That might be a bit too much.
Somewhere around there.
I like a value of 1.2.
I think that's pretty good.
I'm going to press Z and click on
Toggle overlays to get rid of any outlines.
And here is what our result looks like.
I think that looks pretty neat with all
of the clouds in the background and the,
and it's pretty dark.
So there you go.
We've now added an HDR,
and in the next video,
let's add in some pool lights.
