00:04.370 --> 00:05.830
Hello everybody and welcome back.

00:05.840 --> 00:09.030
In this lecture you're going to learn about rendering now.

00:09.110 --> 00:14.030
Many of you would have already done this gone up to the render menu and gone to render image or hits

00:14.090 --> 00:15.150
F 12.

00:15.170 --> 00:16.520
And there we go rendering done.

00:16.520 --> 00:21.620
Yeah well there's a few nuances to it so let's go ahead and find out some more.

00:22.550 --> 00:24.050
Okay everybody Welcome back.

00:24.050 --> 00:27.180
So let's go ahead and just set things up.

00:27.200 --> 00:28.010
Ready to render.

00:28.010 --> 00:32.350
We've got the camera all set up we've got the lights set up we're not amended mode at the moment.

00:32.360 --> 00:34.610
Let's go ahead and switch across the rendered mode.

00:34.610 --> 00:37.880
And by the way you can do that on a pie menu in Blender as well.

00:37.890 --> 00:39.560
I very press Z key.

00:39.740 --> 00:45.460
This pie menu appears where we've got a different selection of rendering options.

00:45.530 --> 00:48.260
We do want rendered so I should leave it there.

00:48.260 --> 00:48.800
Okay.

00:48.890 --> 00:51.680
The first tab we're going to go into is the rendered tab.

00:51.710 --> 00:55.230
And I'm also gonna make this area a little bit wider so we can have a look.

00:55.280 --> 01:00.320
Now the rendering engine that we're currently using is the Eevee engine and we've got two others that

01:00.320 --> 01:06.680
we can pick from cycles will work straight out of the box but you will notice in general that it's slightly

01:06.680 --> 01:12.890
unbalanced with the lighting and you may find at this point that your computer gets louder as the fans

01:12.890 --> 01:20.630
ramp up cycles is a lot more intensive than eevee because it's a real time ray tracing engine rather

01:20.630 --> 01:24.590
than a guessing engine and a kind of a cheetah engine.

01:24.590 --> 01:27.920
But eevee is still wonderful for what we can get done with it.

01:28.220 --> 01:35.090
So if we select cycles it's right from the word go it has the right ambient occlusion it has the right

01:35.090 --> 01:41.720
lighting it does reflections properly whereas evey you have to tell it's all the facts but we get a

01:41.720 --> 01:44.550
very quick output from the word go.

01:44.660 --> 01:50.990
Now you also have a ton of options with the Eevee engine and you have a ton of different options with

01:50.990 --> 01:52.400
the cycles engine.

01:52.400 --> 01:58.520
Now at this point you'll be feeling a little overwhelmed by the sheer choice on offer here but don't

01:58.520 --> 02:01.400
worry we'll cover all of this later in the course.

02:01.520 --> 02:07.220
But for now I'm going to leave it with eevee and I'm going to go down to the next tab not going to change

02:07.310 --> 02:08.640
any of the other settings.

02:08.690 --> 02:10.970
The next tab is about output.

02:10.970 --> 02:14.910
Well let us start off with the resolution this is the resolution of the image itself.

02:15.110 --> 02:17.000
Now 1920 by 10 80.

02:17.000 --> 02:17.330
Great.

02:17.330 --> 02:20.020
We can set this as a screensaver if we want to.

02:20.090 --> 02:26.510
If you wanted it has a four K image instead of setting the resolution accurately what you can do here

02:26.510 --> 02:31.660
is set it 200 percent and that will be the same as rendering output for k.

02:32.570 --> 02:34.010
So let's go ahead and do that now.

02:34.010 --> 02:36.460
Let's go to render render image.

02:36.470 --> 02:38.640
And we get our first image out.

02:38.750 --> 02:40.430
Oh dear what's going on here.

02:40.430 --> 02:41.630
Why is it so zoomed in.

02:41.960 --> 02:44.730
Well it zoomed in because I'm running at 10 ATP signed.

02:44.750 --> 02:46.030
Do need to zoom out.

02:46.040 --> 02:46.540
There we go.

02:46.530 --> 02:48.390
That's the rest of our image.

02:48.410 --> 02:49.060
Excellent.

02:49.070 --> 02:53.550
I can go ahead here and image save as I'm going to call this.

02:53.570 --> 02:58.810
Well I'm in the appropriate folder for me so that's fine save the image.

02:58.810 --> 02:59.780
Off we go.

02:59.800 --> 03:05.440
Now one of the things you can do whilst we're in this particular view which is if we hover over here

03:05.470 --> 03:11.460
the image editor we can go ahead and change the slot number two slot two.

03:11.590 --> 03:18.110
And what that enables us to do is render again and then flick between slot 1 in slot 2 or even another

03:18.130 --> 03:21.090
slot and look at the differences.

03:21.160 --> 03:26.360
So let's do that now and I'm going to do the same thing but this time switch my render engine across

03:26.360 --> 03:28.060
the cycles.

03:28.060 --> 03:35.680
Now you may be able to set your GP you helping out your CPA you depends on your system what we can do

03:35.680 --> 03:43.150
to check for go to edit preferences Oh and it's opened up a window elsewhere there we go and we have

03:43.150 --> 03:49.150
here under the General tab under system we have cycles compute device.

03:49.180 --> 03:53.680
Now I'm not going to go into the full details at the moment in the course there's much more to learn

03:53.680 --> 04:04.270
later on but you can accelerate your rendering with cycles with CUDA with open S.L. or not total so

04:04.300 --> 04:05.080
at the moment.

04:05.080 --> 04:11.740
Not at all would just use your processor in your machine if you've got another option here you may be

04:11.740 --> 04:16.280
able to use a graphics card to help accelerate the rendering.

04:16.280 --> 04:20.100
I'm not going to include and this is a new feature in 2.8.

04:20.260 --> 04:25.900
The graphics card and the CPE working together because that would ruin the screen recording I'm currently

04:25.900 --> 04:27.240
doing for you guys.

04:27.250 --> 04:32.590
Some other leave it set to my graphics card that I'm going to click save user preferences and we'll

04:32.590 --> 04:38.830
have a much more detailed look at cycles later on in the course when we have a dedicated section where

04:38.830 --> 04:41.290
we're going to use it an awful lot.

04:41.320 --> 04:41.810
OK.

04:41.950 --> 04:53.290
So that is all sorted that's go down and change the device to GP you compute for me you might not have

04:53.290 --> 05:00.420
the option or if you get any errors leave it as CPO I'm going to go to render and render image.

05:00.520 --> 05:05.420
Now you'll notice that this takes significantly longer than even he did.

05:05.530 --> 05:06.390
That's not to worry.

05:06.390 --> 05:08.120
That's the nature of the beast.

05:08.200 --> 05:14.470
Plus this is not set up an optimized for this type of rendering at the moment but we'll let it finish

05:14.470 --> 05:17.530
off and we'll then compare the two.

05:17.530 --> 05:17.870
OK.

05:17.890 --> 05:24.930
So there we go we're just finishing off there and now we can go to the slots and pick slot one and pick

05:24.930 --> 05:31.400
a slot to now they're both the same model but they're dramatically different if I go over to the image

05:31.400 --> 05:35.820
I can just savour out and they're both good well I should really go wrong.

05:35.830 --> 05:42.730
Well cycles and of course the other one will be evey are renamed that before I commit this.

05:42.830 --> 05:44.230
And there we go.

05:44.390 --> 05:46.040
That's looking pretty good.

05:46.040 --> 05:51.710
And we can swap it back to eevee which is also looking really good now there are some things that will

05:51.710 --> 05:53.020
stand out.

05:53.030 --> 05:57.480
Couple of things that stand out straightaway is look at the bottom of the foot here.

05:57.510 --> 06:00.010
I change that over to the slot two.

06:00.090 --> 06:03.330
We see that we get a proper dark shadow around there.

06:03.350 --> 06:06.490
In fact it looks like the whole thing's hovering on this side.

06:06.750 --> 06:13.630
Might have to check that just in case I have lifted it up or even push the ground down that is possible.

06:13.640 --> 06:17.240
But look this has far more detail in the shadows at the moment.

06:18.240 --> 06:20.310
Whereas the evil one does not.

06:20.310 --> 06:28.680
Now that is self-explanatory evey need setting up cycles will just work but eevee is a lot quicker and

06:28.680 --> 06:30.270
cycles is a lot slower.

06:30.270 --> 06:34.560
In general there are ups and downs for both of them at this stage.

06:34.560 --> 06:35.400
Don't worry.

06:35.400 --> 06:38.810
Just go with evey so it's nice and quick and then Light's wrong.

06:38.820 --> 06:44.390
We'll learn the differences that actually do make a difference when you come to rendering out your scene.

06:44.580 --> 06:45.510
But there we go.

06:45.510 --> 06:50.700
I've got my scene fully rendered and I've got on my hard drive.

06:50.760 --> 06:53.310
I've got two pictures you know.

06:53.310 --> 06:58.890
That means I can now share them and we'll find out more about sharing in the next lecture.
