All language subtitles for How to Export High-Quality Images from Blender _ Rendering _ Blender basics - English -generated) )

Hi everyone. Many of you were asking how

to take an output image from Blender.

Once you have a 3D model, you are

working on something, how to save it as

an image that you can place in a word

document or a PowerPoint presentation.

So it is very easy to do. So it is

called rendering. So let me show you

that ukulele. Okay. So first here I have

a new project. Here you can see a cube

is there. By default there will be a

light source here. You can see this is a

camera. Okay. So I'll delete everything

so that I'll explain everything one by

one. Let me press delete. So I'll add a

cube quickly. Going to add mesh cube.

Now we have a cube. Okay. So on the

right top side you can see four circles

representing different preview modes.

I'll explain all the basics in another

video. Now let's focus only taking an

output. how to take an image of this

cube. So first we need to make sure that

there is enough lighting.

Okay. So for this cube I'll add a

material on the right side. Here you can

material. Click on new and there is a

material. Click on base color and change

the color. Now you don't see any color.

You need to switch to material preview

mode. Let's add a light. Shift a light

area. Here you can see a light has been

added. it is inside the cube. So simply

select the move tool. You will see this

axis. Move it up like that and scale it

up. We need more area for the light. Uh

so how this light works?

It is adding light parallelly in this

direction. Right? So if we need more

light throughout, we need to increase

the size of the light. So select this

scale tool and left click on the circle

and move it up. Okay. Now go to fourth

preview mode here which will show you

how everything will look like finally

which will appear inside the camera.

Okay. So let's increase the light power.

Go to light properties here. Make sure

that light is selected here. Increase

the light power to higher value 2,000

for example.

Now next we need a camera. So Blender

works same way how photography works. We

have a camera. We look through the

camera. We capture an image. So let's

add a camera. Shift a

camera. When you open a new project,

there will be a camera. Okay. But we

have deleted it. So camera also has been

added at the center. Whenever you add a

new object, it will be added at the

center. So you can locate all the

objects here in this uh window which is

called outliner window. Here you can see

camera. Again I'll select more tool so

that I can move the camera out. See now

I'll move the camera here like that.

Okay. Now we have a camera. Uh if you

click on this camera icon you can see

what camera is actually seeing in the

scene. So that is what we will get as an

output image. Just like photography, we

could have a landscape in front of us,

but how we position the camera that will

decide how the image will be, right? So

the camera is now aligning in this

direction. So you will be getting this

part whatever camera is seeing as an

output image. Okay. So if you click on

camera, this is how you will see. Let me

zoom in using scroll wheel a little bit.

Here you can see hand icon. You can pan

the screen like this.

And first let's lock the camera. Click

on this lock button. Now camera is

locked. Now you don't have to worry

about camera. If you zoom in, zoom out,

camera will remain there. Now I'll

rotate the scenes. Still you can see

this rectangle representing camera. We

are now always looking through the

camera because camera is locked. So now

click and pan the screen. Okay. Now we

have a cube. Now let's quickly take an

image of this cube. It is very easy.

Simply go to render and click on render

image. So when you click on this render

image button, camera captures an image.

See now you have an image. This you can

save by going to image. Click on save

as.

Go to a location that you want to save

the image. Type image one. You can also

see here file format. This is important.

If you click here, you can see all other

file formats. By default, PNG is the

best option. Always go with PNG unless

you are specifically asked for any other

file formats. So, PNG gives you best

output quality. Click on save as image.

Now, if you go to desktop,

double click on the image. See, you have

an image file. But you can see there is

a gray background. How to get rid of

that? For for getting an image with

transparent background, go to render

properties. Here you can see a camera

icon. Click on that. Scroll down. You

can find film. This option is important.

Click and expand that option and

activate transparent. Now look at this

change that is going to happen here when

we activate transparent.

See, now we have a checkerboard which

means the background is transparent.

This is how we will need 3D objects with

no background so that we can directly

place inside PPT or way document. Click

on render render image.

Okay, let's save this again. I'll name

it image two and click on save as image.

Now let's look at the output. Image two.

See this doesn't have any background. If

you open the other one, see it has a

background, gray background. This one

doesn't have any background. It is

actually transparent. Okay. I have

opened a word document. Let's go to

insert image.

Let's select both images that we have

saved. Image one. Insert image.

Image two. See image two doesn't have

any background. Image one has a

background. So this is how we need. So

now you have learned the very basics of

a rendering a scene. Now let's learn

um more about rendering. So this

rendering is called realtime rendering

which means we are using a rendering

engine called EV which means in

photography you could have an old uh

camera right you could have also a

high-end digital camera the output from

both will be different. Similarly, by

default, we have a very fast camera. It

takes an image very fast. It gives you

decent enough quality. But if you need

very hyper realistic output with high

quality, you need to go to camera

properties here. And here you can see if

you expand this window, render engine,

click here and change that to cycles.

Now you can see the output will be of

much higher quality. But it will take a

lot of time. I can talk about cycles in

a different video. But for now, you can

try rendering in both engine. But when

you render with cycles, make sure that

under render maximum samples

uh kept you know very low. Now it is

4,000. I'll keep it 100. 4,000 means it

will take 4,000 samples to get a high

resolution image, high quality image.

But it will take a lot of time. Let's

keep it 100. And also in general cycles

is very slow compared to EV. Okay, keep

these points in mind. So high quality

output like art architecture

visualization if you have devices, if

you have something which need to have

high quality cover art illustrations. So

we more or less try to use cycles. Uh

but it will take more time also. your

computer will require you know much more

better RAM uh processor graphics cards

and so on. Let me open a new project

file open.

Okay, let's render these three objects.

So let's go to render preview mode. We

don't have any lights. I'll add a light.

Shift a light area and move the light

up. See there is some lighting now but

we need more size. Press S and scale it

up and go to light properties here and

change that to higher values. See now we

have enough lighting. So lighting is

also very important part of the

workflow. I'll create a dedicated video

on lighting but for now simply focus on

keeping an area lamp to fill you know

light properly. So now you can see there

is enough light. So let's add a camera.

Shift a camera.

Camera is at the center. I'll move it

here.

And click on camera view. Zoom in. Lock

the camera. Zoom out. Use this hand icon

to pan and center the scene.

Okay. If you think this is good, now you

can go to render properties under film

activate transparent. Now simply click

render render image. That's all. That's

how you render an image. See now you can

straight away use this in your research

paper. If you need high quality image as

I said earlier change this render engine

in render properties to cycles. See now

it takes more time to load but the

quality is much better. Much much

better. So that's the difference. And if

I want this quality, I'll change this to

100 under render. You can see maximum

samples. And

now let's click on render.

But this will take more time compared to

EV. EV is instant. Right? Here you can

see sample. It has to reach 100. So it

is taking time. It is adding pixel by

pixel to get give you best output

possible. By default it it will be

4,000. So it means it will take you know

15 minutes 20 minutes or so uh to

complete all those sampling but most of

the time 100 samples will give you best

output. Okay. So that's all about taking

output image from Blender. I have

covered everything and if you need to

know anything other than this let me

know in the comment box and also if you

go to output properties here you can see

resolution X and Y which means which

represent the size of the image height

and width.

So if you change the height and width of

the camera the output will change right

that's the logic here you can see

resolution X and Y if you change this

value for example let me change this to

1,000 now look at the camera and press

enter see I'll unlock the camera zoom

out see the camera size has changed so

similarly the output image also will

change so if you are preparing a cover

art illustration you need to go to

journal author guideline and find the

value in centimeter or millimeter and go

to uh Google and search for uh cm to

pixel converter and take those values

here x and y. Here you can see

percentage uh resolution. If I change

this to 200 it will take the image in a

double resolution which means this

instead of th00and it will go to 2,000.

it will take more time but the idea is

if you can even render test render with

low resolution so that you'll get an

output faster with lesser resolution

okay and here you can see the file

format you can change the output

location here as well okay so that's all

I think this video summarizes everything

about uh taking an output image

first make sure that the object is ready

second make sure that all the materials

and everything is ready. Then lighting,

then camera. Okay, it is called

rendering.
