00:00:00.000 --> 00:00:02.579
Hello everyone and welcome to a new section.

00:00:02.579 --> 00:00:04.350
In this section I'm gonna be showing you

00:00:04.350 --> 00:00:06.120
how you can turn your render engine from

00:00:06.120 --> 00:00:08.070
cycles over to EV and

00:00:08.070 --> 00:00:10.785
convert your whole scene into that render engine.

00:00:10.785 --> 00:00:13.095
Av is quite different from cycles,

00:00:13.095 --> 00:00:15.630
lighting, glass, reflections.

00:00:15.630 --> 00:00:17.415
All of that works much differently.

00:00:17.415 --> 00:00:19.920
And I'm going to be talking about how it works and how

00:00:19.920 --> 00:00:22.905
to optimize your scene to make it look really nice.

00:00:22.905 --> 00:00:24.960
So let's go ahead and get started.

00:00:24.960 --> 00:00:26.490
Here is our final scene,

00:00:26.490 --> 00:00:28.290
it using the Cycles Render Engine.

00:00:28.290 --> 00:00:29.940
And before you change anything,

00:00:29.940 --> 00:00:31.140
make sure you save it as

00:00:31.140 --> 00:00:32.895
a new blend file so you can

00:00:32.895 --> 00:00:35.619
always go back to your one in cycles.

00:00:35.619 --> 00:00:37.730
So with this blend file selected,

00:00:37.730 --> 00:00:39.545
I'm going to press Control Shift and

00:00:39.545 --> 00:00:42.065
S to save it as a new blender file.

00:00:42.065 --> 00:00:44.630
I'm going to call it EV Tutorial

00:00:44.630 --> 00:00:48.155
3 because I've tried to record this three times so far.

00:00:48.155 --> 00:00:51.335
And once you've done that, you can click on Save As.

00:00:51.335 --> 00:00:53.570
Now that we've saved it as a new blender file,

00:00:53.570 --> 00:00:56.330
we can go to the EV render engine and not

00:00:56.330 --> 00:00:57.410
have to worry about messing

00:00:57.410 --> 00:00:59.480
anything up in these cycles version.

00:00:59.480 --> 00:01:02.015
So let's switch over to EV.

00:01:02.015 --> 00:01:03.950
Let's take a look at our scene by hitting

00:01:03.950 --> 00:01:06.350
Z and going into rendered view.

00:01:06.350 --> 00:01:08.420
This might take a couple of minutes

00:01:08.420 --> 00:01:10.370
or you can see there it was pretty quick.

00:01:10.370 --> 00:01:13.760
And you can see our scene doesn't really look that great.

00:01:13.760 --> 00:01:15.380
The windows are currently not

00:01:15.380 --> 00:01:17.675
working and we'll fix that in just a second.

00:01:17.675 --> 00:01:19.130
But first off, I wanted to

00:01:19.130 --> 00:01:21.020
fix some of the Render Settings.

00:01:21.020 --> 00:01:22.370
I'm going to zoom in over here

00:01:22.370 --> 00:01:24.110
and show you what some of these do.

00:01:24.110 --> 00:01:26.660
First off, we're going to turn on ambient inclusion.

00:01:26.660 --> 00:01:28.640
You can see this adds a little bit of darkness

00:01:28.640 --> 00:01:30.860
around the corners of all of the objects.

00:01:30.860 --> 00:01:32.540
You can control the strength of this

00:01:32.540 --> 00:01:34.235
by turning up the factor amount.

00:01:34.235 --> 00:01:35.690
If you bring those up to three,

00:01:35.690 --> 00:01:37.295
you can see it's a lot darker.

00:01:37.295 --> 00:01:39.815
I'm just going to leave it at a value of one.

00:01:39.815 --> 00:01:42.440
You can also turn on a bloom and this is going to need

00:01:42.440 --> 00:01:44.810
to add a glow around the lights.

00:01:44.810 --> 00:01:46.160
So if I come over to here,

00:01:46.160 --> 00:01:47.600
you can see with it off,

00:01:47.600 --> 00:01:48.755
there is no glow.

00:01:48.755 --> 00:01:49.820
But with that turned on,

00:01:49.820 --> 00:01:52.370
it adds a nice glow around that area,

00:01:52.370 --> 00:01:53.810
which is pretty nice.

00:01:53.810 --> 00:01:56.030
You can control the strength of this bloom by

00:01:56.030 --> 00:01:58.430
turning up the intensity slider.

00:01:58.430 --> 00:02:01.250
I'm just going to leave it at the default settings.

00:02:01.250 --> 00:02:03.410
One very important setting that we need to

00:02:03.410 --> 00:02:05.465
turn on is a screen space.

00:02:05.465 --> 00:02:08.255
Reflections. Make sure that is enabled

00:02:08.255 --> 00:02:09.410
and that will change how

00:02:09.410 --> 00:02:11.675
your reflections work in your entire scene.

00:02:11.675 --> 00:02:13.160
You can see with it off there

00:02:13.160 --> 00:02:14.645
is no reflection in the water,

00:02:14.645 --> 00:02:17.810
but with it turned on, we now have reflection.

00:02:17.810 --> 00:02:19.910
Open up this panel and make

00:02:19.910 --> 00:02:22.055
sure refraction is also turned on.

00:02:22.055 --> 00:02:23.660
This will allow us to modify

00:02:23.660 --> 00:02:25.310
the glass materials we can actually

00:02:25.310 --> 00:02:28.670
see through it and then also turn off half raise traced.

00:02:28.670 --> 00:02:29.795
So we're actually using

00:02:29.795 --> 00:02:33.030
the full resolution on all of the rays.

00:02:33.220 --> 00:02:36.350
Next up we're going to open up these shadows.

00:02:36.350 --> 00:02:39.050
The cube size is currently set to five at 12.

00:02:39.050 --> 00:02:42.080
This will give us a kind of low resolution shadow.

00:02:42.080 --> 00:02:45.620
So let's bring that up to a value of 248.

00:02:45.620 --> 00:02:47.030
That's just going to increase

00:02:47.030 --> 00:02:49.130
the resolution of all of our shadows.

00:02:49.130 --> 00:02:53.540
The cascade side, I'm also going to bring up to 2048.

00:02:53.540 --> 00:02:57.020
And that will also make and that will also help with

00:02:57.020 --> 00:02:58.670
the resolution of the shadows

00:02:58.670 --> 00:03:00.575
and making sure everything looks good.

00:03:00.575 --> 00:03:03.470
You can also turn on high bit depth shadows

00:03:03.470 --> 00:03:06.410
and that will increase the resolution as well.

00:03:06.410 --> 00:03:09.170
The indirect lighting we will cover later,

00:03:09.170 --> 00:03:10.910
but for now we're going to close that off.

00:03:10.910 --> 00:03:13.040
And I think everything else is good to go.

00:03:13.040 --> 00:03:15.395
We have medium, high contrast in the color management.

00:03:15.395 --> 00:03:17.915
So now let's work on the materials.

00:03:17.915 --> 00:03:20.090
I'm going to select the window material

00:03:20.090 --> 00:03:22.820
first and then go over to the Material tab.

00:03:22.820 --> 00:03:25.609
Make sure you have the glass material selected.

00:03:25.609 --> 00:03:27.530
And how this works is we need to

00:03:27.530 --> 00:03:29.990
turn on its screen space refraction.

00:03:29.990 --> 00:03:31.730
And then we'll be able to see

00:03:31.730 --> 00:03:34.745
inside our house as you can see there.

00:03:34.745 --> 00:03:38.120
And that is basically all we really need to do.

00:03:38.120 --> 00:03:39.590
As with the other materials.

00:03:39.590 --> 00:03:41.765
We're going to select our pool water,

00:03:41.765 --> 00:03:43.909
turn on screen at space refraction.

00:03:43.909 --> 00:03:46.010
And then we should be able to see inside ice,

00:03:46.010 --> 00:03:47.930
you can see the other material

00:03:47.930 --> 00:03:50.030
that we need to fix is all of the plants.

00:03:50.030 --> 00:03:53.255
You can see since they're using a transparent texture,

00:03:53.255 --> 00:03:56.525
is giving us a black outline over every single leaf.

00:03:56.525 --> 00:03:59.390
So what we need to do is selected that material.

00:03:59.390 --> 00:04:01.535
We have the leaves material selected.

00:04:01.535 --> 00:04:03.050
Underneath the blend mode,

00:04:03.050 --> 00:04:05.420
we need to select Alpha hashed.

00:04:05.420 --> 00:04:06.980
And that's going to get rid of

00:04:06.980 --> 00:04:09.470
that transparency and give us that this effect,

00:04:09.470 --> 00:04:11.090
which looks a lot better.

00:04:11.090 --> 00:04:12.590
Let's do the same thing for

00:04:12.590 --> 00:04:14.360
this object over here inside the house.

00:04:14.360 --> 00:04:16.265
Let's go ahead and select it.

00:04:16.265 --> 00:04:17.705
And then on the blend mode,

00:04:17.705 --> 00:04:20.255
set it over to Alpha hashed.

00:04:20.255 --> 00:04:22.160
Finally, it will come up here to

00:04:22.160 --> 00:04:24.380
the big tree and do the same thing.

00:04:24.380 --> 00:04:27.080
And you might think to switch it over to alpha blended.

00:04:27.080 --> 00:04:29.360
But the problem with that is it doesn't

00:04:29.360 --> 00:04:32.105
really work with and multi-layer transparency.

00:04:32.105 --> 00:04:35.105
You can see here, if I switch it over to alpha blend,

00:04:35.105 --> 00:04:37.340
it's not going to display those at all.

00:04:37.340 --> 00:04:39.890
It's only going to display the trees.

00:04:39.890 --> 00:04:41.795
So switching it over to

00:04:41.795 --> 00:04:44.330
Alpha hat allows other transparent objects.

00:04:44.330 --> 00:04:45.380
You can actually see through

00:04:45.380 --> 00:04:46.910
them and see that transparency,

00:04:46.910 --> 00:04:48.515
which is what we want.

00:04:48.515 --> 00:04:51.005
And that looks much better.

00:04:51.005 --> 00:04:52.640
You also might notice that we have

00:04:52.640 --> 00:04:54.575
a lot of light bleed all over the place,

00:04:54.575 --> 00:04:56.915
especially over here in the top right.

00:04:56.915 --> 00:04:59.300
Eb is known for rendering light bleed and

00:04:59.300 --> 00:05:01.640
there are a couple of ways to fix that.

00:05:01.640 --> 00:05:04.475
Let's go ahead and select the lab in our scene.

00:05:04.475 --> 00:05:06.470
And the first thing that we need to do to

00:05:06.470 --> 00:05:08.750
help prevent that light bleed is to

00:05:08.750 --> 00:05:13.295
open up the shadow and then turn on at contact shadows.

00:05:13.295 --> 00:05:15.590
What contact shadows does is it basically

00:05:15.590 --> 00:05:17.660
takes the light and where there

00:05:17.660 --> 00:05:19.685
is a shadow and then adds a little bit

00:05:19.685 --> 00:05:22.085
of a shadow really close to that edge.

00:05:22.085 --> 00:05:25.130
That edge is determined by the distance slider.

00:05:25.130 --> 00:05:26.360
So if I drag this up,

00:05:26.360 --> 00:05:28.640
that might help prevent a little bit,

00:05:28.640 --> 00:05:30.260
but you can see it's still there.

00:05:30.260 --> 00:05:32.270
So another way to fix light bead is

00:05:32.270 --> 00:05:34.145
to add some thickness to your object.

00:05:34.145 --> 00:05:35.690
So we're gonna go ahead and do that,

00:05:35.690 --> 00:05:37.310
select your main A-frame of

00:05:37.310 --> 00:05:39.320
the house and go over to the modifier,

00:05:39.320 --> 00:05:41.270
tap the thickness slider

00:05:41.270 --> 00:05:43.880
here and the solidify modifier we're going to bring up.

00:05:43.880 --> 00:05:45.230
First though I'm going to set

00:05:45.230 --> 00:05:47.000
the offset all the way up to one.

00:05:47.000 --> 00:05:49.550
So instead of extending inside the house,

00:05:49.550 --> 00:05:50.960
the thickness is actually going to

00:05:50.960 --> 00:05:52.955
go on the outside of the house.

00:05:52.955 --> 00:05:54.785
So for the thickness slider,

00:05:54.785 --> 00:05:58.560
I'm going to set that up to 0.2 and enter.

00:05:59.080 --> 00:06:02.450
And hopefully that will prevent any light bleed that's in

00:06:02.450 --> 00:06:04.970
these corners will do the same thing over here.

00:06:04.970 --> 00:06:06.875
We're going to select this plane

00:06:06.875 --> 00:06:08.225
or this object right here.

00:06:08.225 --> 00:06:09.740
And underneath the thickness,

00:06:09.740 --> 00:06:12.290
we're going to go up two instead of point

00:06:12.290 --> 00:06:13.460
2 because that's a bit too

00:06:13.460 --> 00:06:15.080
much on this side of the house.

00:06:15.080 --> 00:06:18.980
Let's go up to 0.15 and Enter.

00:06:18.980 --> 00:06:21.260
You can see inside that it's

00:06:21.260 --> 00:06:22.820
clipping into that object now.

00:06:22.820 --> 00:06:24.110
So on the offset,

00:06:24.110 --> 00:06:26.820
let's try a value of 0.

00:06:27.270 --> 00:06:29.575
That will look a little bit better.

00:06:29.575 --> 00:06:30.640
And as you can see though,

00:06:30.640 --> 00:06:32.905
there is still some light bleed right there.

00:06:32.905 --> 00:06:36.234
Another way to fix that is to lower the lights.

00:06:36.234 --> 00:06:39.145
So what we can do is select of those lights right here.

00:06:39.145 --> 00:06:41.200
I'll select this one as well.

00:06:41.200 --> 00:06:43.630
The select those objects will go back

00:06:43.630 --> 00:06:46.435
into rendered view and drag this underneath.

00:06:46.435 --> 00:06:48.610
And as you can see, once we drag it underneath,

00:06:48.610 --> 00:06:50.695
that light is now gone.

00:06:50.695 --> 00:06:52.480
Let's go back into camera view

00:06:52.480 --> 00:06:53.590
and double-check the rest of

00:06:53.590 --> 00:06:54.760
the scene and I think everything

00:06:54.760 --> 00:06:57.070
else is looking pretty good.

00:06:57.070 --> 00:06:59.815
Now let's talk about indirect lighting.

00:06:59.815 --> 00:07:01.690
Indirect lighting allows there to be

00:07:01.690 --> 00:07:04.015
light bounces in EV, at the moment,

00:07:04.015 --> 00:07:05.920
there is no light bounces and that's why

00:07:05.920 --> 00:07:08.925
the whole scene looks very plain and boring.

00:07:08.925 --> 00:07:11.630
So to add light bounces and EV,

00:07:11.630 --> 00:07:13.415
you need to add in a new object.

00:07:13.415 --> 00:07:14.870
We're going to press Shift a and go

00:07:14.870 --> 00:07:16.220
over to the light probe

00:07:16.220 --> 00:07:19.549
and then add in any radiance volume object.

00:07:19.549 --> 00:07:21.110
With this object selected,

00:07:21.110 --> 00:07:23.900
we need to scale it up to match the rest of the scene.

00:07:23.900 --> 00:07:27.035
I'm going to go into top view by hitting seven.

00:07:27.035 --> 00:07:29.270
And then I'm going to press S to scale and

00:07:29.270 --> 00:07:31.940
scale it up to fit the entire house.

00:07:31.940 --> 00:07:33.920
Just like this.

00:07:33.920 --> 00:07:36.050
So right about there looks pretty good.

00:07:36.050 --> 00:07:38.660
You want to make sure that this is as small as it can be

00:07:38.660 --> 00:07:40.220
because it's going to take a long time

00:07:40.220 --> 00:07:41.900
to bake the indirect lighting.

00:07:41.900 --> 00:07:44.600
We're gonna go into front view now and scale

00:07:44.600 --> 00:07:47.465
this along the z-axis until it fits the house.

00:07:47.465 --> 00:07:49.040
So right about there and then we'll

00:07:49.040 --> 00:07:50.720
drag it down right about there.

00:07:50.720 --> 00:07:52.820
Looks pretty good.

00:07:52.820 --> 00:07:55.190
Let's go over to the settings and we're

00:07:55.190 --> 00:07:56.840
going to talk about the resolution.

00:07:56.840 --> 00:07:58.390
The resolution is how good at

00:07:58.390 --> 00:08:00.335
the indirect lighting will work.

00:08:00.335 --> 00:08:02.060
You can see with the screenshots

00:08:02.060 --> 00:08:03.440
so that a low resolution,

00:08:03.440 --> 00:08:05.990
there's not a very high-quality look

00:08:05.990 --> 00:08:08.840
to the bounces of light with a high resolution,

00:08:08.840 --> 00:08:10.130
it looks a lot better.

00:08:10.130 --> 00:08:11.660
So along the z-axis,

00:08:11.660 --> 00:08:12.830
I'm going to leave it at four,

00:08:12.830 --> 00:08:14.255
but along the x and the y,

00:08:14.255 --> 00:08:16.775
I'm going to bring it up to a value of eight.

00:08:16.775 --> 00:08:18.560
You also don't want to go too

00:08:18.560 --> 00:08:20.450
high with these values because sometimes it will

00:08:20.450 --> 00:08:21.890
look a little bit weird and you'll

00:08:21.890 --> 00:08:24.155
have more light bead than usual.

00:08:24.155 --> 00:08:27.230
I found that a value of eight for the x and y and

00:08:27.230 --> 00:08:28.820
a value of four for the z

00:08:28.820 --> 00:08:30.845
looks pretty good for this scene.

00:08:30.845 --> 00:08:33.110
So now that we've done that, let's jump back over to

00:08:33.110 --> 00:08:36.515
the EV settings and then click on bake indirect lighting.

00:08:36.515 --> 00:08:38.870
And that will make the entire scene have bound sliding.

00:08:38.870 --> 00:08:40.865
And it will look a really nice.

00:08:40.865 --> 00:08:43.640
Now that the indirect lighting has finished baking,

00:08:43.640 --> 00:08:46.160
Let's press Z and go into rendered view.

00:08:46.160 --> 00:08:48.290
As you can see, there is no lightweight

00:08:48.290 --> 00:08:50.330
anywhere and it is looking much better.

00:08:50.330 --> 00:08:51.860
The interior now has bounced

00:08:51.860 --> 00:08:53.675
lighting and it looks really nice.

00:08:53.675 --> 00:08:56.015
It almost looks good as cycles.

00:08:56.015 --> 00:08:58.850
So now that we've added all of the indirect lighting,

00:08:58.850 --> 00:09:01.040
I think we are ready to render this out.

00:09:01.040 --> 00:09:02.420
So for the render samples,

00:09:02.420 --> 00:09:05.390
I'm going to go up to a value of 128.

00:09:05.390 --> 00:09:07.760
I don't think you need to go any higher than that.

00:09:07.760 --> 00:09:10.430
And make sure you save your project once again,

00:09:10.430 --> 00:09:11.960
then you can go over to render

00:09:11.960 --> 00:09:14.150
and then click on Render Image.

00:09:14.150 --> 00:09:16.130
This might take a minute or two

00:09:16.130 --> 00:09:17.930
depending on how fast your computer is.

00:09:17.930 --> 00:09:19.175
But once it's done rendering,

00:09:19.175 --> 00:09:21.770
it'll take those composite knows that we've

00:09:21.770 --> 00:09:23.270
created in the last section

00:09:23.270 --> 00:09:25.595
and then apply it to the EV render.

00:09:25.595 --> 00:09:27.620
And the rotor has finished and it

00:09:27.620 --> 00:09:29.390
only took about 20 seconds.

00:09:29.390 --> 00:09:32.000
And as you can see, it does look really nice.

00:09:32.000 --> 00:09:34.130
If you want to change how the render looks,

00:09:34.130 --> 00:09:36.020
you can exit out of this window and go over

00:09:36.020 --> 00:09:38.450
to the compositing space right here.

00:09:38.450 --> 00:09:40.850
We don't really need a lot of these nodes.

00:09:40.850 --> 00:09:41.930
Like for example, we don't need

00:09:41.930 --> 00:09:43.625
a gamma nodes, we can get rid of that.

00:09:43.625 --> 00:09:45.260
We'll plug it into here.

00:09:45.260 --> 00:09:47.780
And then you can change the color if you wanted to.

00:09:47.780 --> 00:09:48.950
So if you wanted the shadows to

00:09:48.950 --> 00:09:50.270
be just a tiny bit brighter,

00:09:50.270 --> 00:09:51.650
you can drive that up.

00:09:51.650 --> 00:09:53.300
If the highlights are too bright,

00:09:53.300 --> 00:09:55.940
you can drive that down and play around with the nodes

00:09:55.940 --> 00:09:59.150
just like you did before in the cycles version.

00:09:59.150 --> 00:10:01.445
Once you are happy with the nodes that you've set up,

00:10:01.445 --> 00:10:04.325
you can press F 11 to bring back your scene,

00:10:04.325 --> 00:10:05.930
come over to here and type in

00:10:05.930 --> 00:10:07.970
viewer and select the viewer node.

00:10:07.970 --> 00:10:10.475
And then you can press Shift Alt S to save it.

00:10:10.475 --> 00:10:13.460
Or you can go over to image and click on Save As,

00:10:13.460 --> 00:10:15.200
and then name it however you want.

00:10:15.200 --> 00:10:18.350
I'm going to call it AB Tutorial 2,

00:10:18.350 --> 00:10:20.720
and then I'll click on Save As.

00:10:20.720 --> 00:10:22.400
There we go. We've now rendered

00:10:22.400 --> 00:10:24.605
arsine using the EV Render Engine.

00:10:24.605 --> 00:10:26.420
Thank you very much for watching this tutorial

00:10:26.420 --> 00:10:28.220
if you created your own, I'd love to see it.

00:10:28.220 --> 00:10:29.300
So make sure to post it in

00:10:29.300 --> 00:10:31.505
the assignments or the projects.

00:10:31.505 --> 00:10:32.960
Now just for fun,

00:10:32.960 --> 00:10:34.610
here's a comparison with the EV

00:10:34.610 --> 00:10:37.100
render engine and the Cycles Render Engine.

00:10:37.100 --> 00:10:38.570
You can take a look at these and see

00:10:38.570 --> 00:10:41.150
the differences and find the one that you like.

00:10:41.150 --> 00:10:43.550
As you can see, they both look really nice.

00:10:43.550 --> 00:10:44.750
I think these Cycles render

00:10:44.750 --> 00:10:46.250
engine looks a little bit better.

00:10:46.250 --> 00:10:48.050
It looks a little bit more realistic.

00:10:48.050 --> 00:10:49.610
But the IV, your render engine,

00:10:49.610 --> 00:10:50.930
the render time only took

00:10:50.930 --> 00:10:54.440
20 seconds and it still looks really good.

00:10:54.440 --> 00:10:56.450
So they both have their strengths and

00:10:56.450 --> 00:10:58.025
weaknesses, but there it is.

00:10:58.025 --> 00:10:59.525
That's gonna do it for this section.

00:10:59.525 --> 00:11:00.860
Thank you again for watching and

00:11:00.860 --> 00:11:03.240
I'll see you in the next one.
