00:00So hello everyone, welcome back to the channel Web4Click.
00:04Today we will take you to the websites of 3D models.
00:08And on the website of 3D models, you must be downloading a lot of such 3D models daily.
00:14Some of these 3D models are so beautiful that they will surprise you.
00:19And you must be thinking that how are they made?
00:23As you can see that we have a girl's model.
00:26And the lighting behind it is set so beautifully.
00:30And the shining in it is so beautiful.
00:33In addition to this, you will find many other models here.
00:37In which its texture will surprise you.
00:40And you can see how beautiful the words are given here.
00:43In which the textures look so realistic.
00:46If you use them by rigging, they will look real here.
00:50In addition to this, there are many other types of metals.
00:53And you can see an asteroid here.
00:56Which is so beautiful to see here.
00:58Inside this asteroid, you can see different types of blue color metals.
01:04Whose shining is very beautiful to see here.
01:07Now the first question that arises in our mind is that how are such models made?
01:12So let me show you one thing here first.
01:16Here you can see an old type of electrical machine.
01:21Which has been given a very good texture here.
01:25Which is looking very realistic.
01:27But when we make any model in the starting.
01:30So you will see something like this here.
01:33And when we use some colors and textures in it.
01:36So this type of model will come to us here.
01:40If we want to put life in this model.
01:42And we have to show it completely realistic.
01:45Something like this.
01:47So for that we use shaders.
01:50Come, let me show you some more things.
01:52Here you can see my Santa Claus in the glass.
01:55How beautiful it is looking here.
01:58In addition to this, you can see a car here.
02:00You will see how good the shining will be here.
02:03When we make this car in the starting.
02:05So you will see something like this here.
02:08When we apply colors and textures here.
02:12So that car looks like this in our blender.
02:16But if we want to put life in this car.
02:18And if we want to make this type realistic.
02:21So for that we have to use shaders.
02:24So let's see what these shaders are.
02:28So as soon as we come inside the blender.
02:30So here we will get a by default cube.
02:33And if you click on the material here.
02:35So here you can see this by default color.
02:38It is automatically applied to it.
02:40If you want to see any color.
02:42So for that you have to go to this option.
02:45Then only you can see the color here.
02:47By default whenever you assign any new material to it.
02:50So here you will get an option of surface.
02:53In the option of surface here by default.
02:56You will get principal bsdf selected here.
02:59You will get all these things here.
03:02Along with this if you go to shading here.
03:04First of all, those who are watching this video and are new.
03:07Let me tell them that the whole course of blender is going on here.
03:10And so far I have made 47 episodes.
03:13If you are also interested in advanced level animation and movie vfx.
03:18So subscribe to the channel now.
03:21And you will get all the episodes in the web for click playlist.
03:24So first of all, I turn this panel up here.
03:28And if I press the shift a button here.
03:30So all these nodes of my texture will come here.
03:34And here you will get an option of shader.
03:37So first of all, I have picked up the shader in it.
03:40I have picked up the shader because all the other things follow it.
03:44And we will understand all the options one by one in detail.
03:47Apart from the shader, you can see the texture here.
03:50If you want to make a brick texture.
03:52Apart from this, from the texture of the chair.
03:54You will get different types of textures of the environment here.
03:57Which we will understand in detail.
03:59Today's video is on the shader.
04:02And you can go to the shader.
04:04You will get all these shaders here.
04:07Now let's go back to our layout.
04:09In the layout, you will see that all these shaders are there.
04:15But the first question is what are shaders?
04:19So let's understand this in a little detail.
04:22If you have ever been to school in your life.
04:25Then you must have heard about light.
04:27And let me tell you one thing.
04:29Whatever we see here.
04:31We see it because of the light.
04:34And how the light is reflected on it.
04:39How it is turning in the other direction.
04:42It tells us how the object will look to us.
04:45Let's understand this with an example.
04:48Suppose we have an object.
04:50And if the light falls on it.
04:52And it goes right across it.
04:55So the things of this type look transparent to us.
04:59For example, glass or water.
05:02In this type of things, the light goes right across it.
05:06Similarly, when the light falls on an object.
05:10And it hits and goes back in the same direction.
05:14So its shining increases a lot.
05:18And we can call it a mirror.
05:20That is, the mirror we see.
05:22In which we see the face.
05:24The light falls on it and reflects it in the same direction.
05:29That's why we see our reflection in the mirror.
05:33Apart from this, if our light falls and goes a little back.
05:38Then we see some metallic things.
05:41That is, like our steel, gold.
05:45So in this way, our different types of light.
05:48Which hits our object and shows us different types of things.
05:53For that, our shaders have been made.
05:57Now if we come back to the Blender.
05:59If we look at all our shaders again.
06:02Then more than half of our shaders.
06:05You will see BSDF here.
06:08You can see more than half of our shaders.
06:11BSDF is here.
06:13So let's first find out what is BSDF?
06:17BSDF has a full form.
06:19Bidirectional Scattering Distribution Function
06:23First of all, let me tell you that whatever light falls on an object.
06:27It spreads in different directions.
06:30This is called Bidirectional Scattering Distribution Function.
06:34The first option in this is Bidirectional.
06:37This means that whatever light is falling on the surface.
06:41At what angle is it reflecting there?
06:44Scattering and Distribution both mean Spreading in Hindi.
06:48But these two are different from each other.
06:51Let's understand how they are different.
06:54When our light falls on a surface.
06:57At what angle is it reflecting there?
07:00This is called Scattering.
07:03Distribution means that when our light falls on a surface.
07:07It spreads in different directions.
07:10This is called Distribution.
07:12That is, the area from which it is reflecting.
07:15This is called Scattering.
07:18When the light falls on the surface.
07:21It spreads in different directions.
07:24This is called Distribution.
07:27This whole process is called Function.
07:30This is how Bidirectional Scattering Distribution Function works.
07:33It is a process of colliding light with the surface.
07:37How much light will collide here?
07:40How much will it reflect?
07:43We have given different types of BSDF for this.
07:46Let's understand all the BSDF one by one.
07:49Let's understand all the BSDF one by one.
07:52We will explain the rest of the BSDF in between.
07:55We will explain the rest of the BSDF in between.
07:58The first is Anisotropic BSDF.
08:01I have taken a camera to explain to you.
08:04I have shown you the upper part of this camera.
08:07If you look at the button of this camera.
08:10You can see a different type of shining in the button.
08:13You can see a different type of shining in the button.
08:16If I zoom in.
08:19You can see that my light is dividing in two directions.
08:22One direction is this side.
08:25The other direction is this side.
08:28Both these triangles are empty.
08:31What will happen in Anisotropic BSDF?
08:34My light will fall on this.
08:37And it will divide in two directions.
08:40Let me show you properly.
08:43I have taken a model of a black color CD.
08:46As soon as I turn it around.
08:49The shining in which my light is divided in two directions.
08:52We make it with the help of Anisotropic BSDF.
08:55We make it with the help of Anisotropic BSDF.
08:58You will find many more examples.
09:01You will find many more examples.
09:04Let's go to the Blender.
09:07Let's create this shining with the help of Anisotropic BSDF.
09:10We are on the Blender screen.
09:13I will apply Anisotropic BSDF.
09:16I will apply Anisotropic BSDF.
09:19As soon as I apply it.
09:22You will see that the shining has changed in my cube.
09:25As soon as I render it.
09:28I will see it like this.
09:31Let me tell you one thing.
09:34If you work on advanced level.
09:37There are many things in EV mode.
09:40Which stops me from working.
09:43Because there are many things in light.
09:46In which my EV mode does not support.
09:49First of all, I convert it into a cycle.
09:52As soon as I convert it into a cycle.
09:55The shining that was visible on it.
09:58I can see that shining on this cube.
10:01I can see that shining on this cube.
10:04If the configuration of your system is less in cycles.
10:07First of all, you will get the option of denoise.
10:10You have to tick on it.
10:13I will reduce the maximum number of samples.
10:16I will reduce it to 50.
10:19This will make rendering easier for you.
10:22First of all, because we are working on node.
10:25I will divide it into two parts.
10:28I will make this part my shader.
10:31I will make this part my shader.
10:34I will close this window by pressing the N button.
10:37You can see my anisotropic BSDF has come here.
10:40If you want to take it here.
10:43You just have to press the A button.
10:46You will get all these shaders in the shader.
10:49You can select directly from here.
10:52Or you can search Anisotropic BSDF.
10:55It will come here.
10:58You can use it from both sides.
11:01If you want to go to material.
11:04You will get a lot of functions in it.
11:07Roughness means if you want to reduce the shining.
11:10The more you increase the roughness.
11:13The more it will spread.
11:16The more you reduce the roughness.
11:19The more the graph will increase.
11:22You can see the shining on both sides.
11:25You can control it with roughness.
11:28You can control it with roughness.
11:31We can cover the black part with anisotropic.
11:34We can cover the black part with anisotropic.
11:37If I change the value from 0.5 to 0.9.
11:40If I change the value from 0.5 to 0.9.
11:43You can see the black color value has increased.
11:46And this part has reduced.
11:49I will change it to 0.5.
11:52Now what does the rotation do?
11:55If I want to rotate the shining.
11:58If I want to rotate the shining.
12:01I will move this rotation forward.
12:04You can see my rotation is rotating.
12:07I can rotate the shining with the help of rotation.
12:10I can rotate the shining with the help of rotation.
12:13If you want to animate the shining.
12:16You can easily animate it.
12:19Let's see how to animate it.
12:22To animate it, bring the cursor to 0.
12:25I have set the rotation to 0.
12:28If I press the I button, you can see the color has changed.
12:31If I press the I button, you can see the color has changed.
12:34I will set the time line to 40.
12:37I will set the rotation to full.
12:40I will set the rotation to full.
12:43I will set the rotation to full.
12:46I will press the I button again.
12:49Now you can see I can't see any keyframe.
12:52Now you can see I can't see any keyframe.
12:55The reason for this is when you select the node.
12:58The keyframe will be visible.
13:01The reason for this is when you select the node.
13:04The keyframe will be visible.
13:07Now I will play it.
13:10Press the I button to play the animation.
13:13Press the I button to play the animation.
13:16Press the I button to play the animation.
13:19Press the I button to play the animation.
13:22Now I will remove this keyframe.
13:25I will remove the timeline as well.
13:28If I rotate with the help of rotation.
13:31If I move the keyframe, my shining will rotate.
13:34But you can use shinings in all formalities.
13:37we can use this shining in different ways.
13:41Let's see how we do it.
13:43As an example, you can see a model here
13:46and you can see a circle type of shine in it.
13:49Here is this type of shine and here is another type of shine.
13:53This is also made with the help of anisotropic BSDF.
13:58Now let's see how it is made here practically.
14:02Here I remove it and
14:04I take a UV sphere in its place.
14:07I smooth it by right-clicking.
14:09Shade smooth will make it smooth.
14:11I click on New here and generate a new material.
14:15I select Anisotropic BSDF instead of Principle BSDF.
14:21I can also do it from here or by pressing Shift A directly
14:24I can also select it here.
14:26As soon as I selected it here,
14:28you saw that it was applied on it.
14:31The reflection in it is coming from the same type as in my cube.
14:35If I want to change it,
14:37I can change it with the help of the rotation option here.
14:40As soon as I click on it and rotate it,
14:42you will see that my area has come from this type here.
14:47If you want to change its color from here,
14:50you can do any other color of your object here.
14:53Let's say I take a color of this type here.
14:57As you can see,
14:59my circle-type object has come to me exactly in the same way
15:04as it was coming in my 3D models.
15:08So this was our Anisotropic BSDF.
15:11When we do more modeling,
15:13we will generate different types of shine.
15:16For now, you must practice it
15:19so that you can understand these things easily.
15:22Now let's move a little further
15:24and go to the next BSDF.
15:26Again, we will click on the surface here
15:28and if I look at my next BSDF here,
15:31then our second BSDF is Diffuse BSDF.
15:35So let's move ahead and go to our second BSDF.
15:39As soon as I click on the surface here
15:41and I will come to my second BSDF here,
15:43that is our Diffuse BSDF.
15:45As soon as I select Diffuse BSDF here,
15:48a node named Diffuse has been created here.
15:52In this, you will get only two options
15:54Color and Roughness.
15:56So I had selected a green color here,
15:58so this green color is coming in it.
16:00If I want, I can select any other color here.
16:03For now, I will make it a little of this type of color.
16:06If you change the Roughness here,
16:09then you will not see any special effect here.
16:12Now let's first understand
16:14what is this Diffuse and how does it work.
16:19So to explain to you, I have taken an image here.
16:22Here you can see that whatever is my upper area,
16:25it is coming in my water in a very good way in reflection.
16:29So in this way, you will get a lot of such scenes
16:32in which our upper area will reflect in the water in this way.
16:36So in this water area,
16:38I can see everything clearly here.
16:41Now let's go to the second picture.
16:43Here too you can see that whatever is my upper area,
16:46it is being reflected here,
16:48but now it is not being clearly reflected here.
16:51You can see how blurry it is,
16:53but it is very beautiful here.
16:56But if you look at this picture,
16:58then it is clearly visible here.
17:00So if I blur this reflection here,
17:03then I have diffused it here.
17:07So let's do it practically now.
17:10So again we have come to our Blender
17:12and here I have taken an option of Diffuse already.
17:16So first of all, we have to do one thing
17:18I will do this in my EV again
17:20because my Diffuse works in EV too.
17:23You have to pay special attention to this thing
17:25that there are many such things that will work in our cycles.
17:29If I go to Materials,
17:30now I have told you the Anisotropic BSDF here first.
17:34You will see its effect here in my last globe.
17:40It will never be visible in my color option.
17:44So my Diffuse will be visible in the color one.
17:47That's why I have selected color from here.
17:49I have selected EV from here.
17:51Let's go back to our mode.
17:53And let's come back to our screen.
17:56If you look here in Shading,
17:58you can see some strange background in Shading.
18:01If I want to make the same background here too,
18:04then I have told you this thing before in the last video.
18:07You simply have to increase the word opacity here a little bit.
18:12And my background will be blurred here.
18:15The background that I have blurred here,
18:17I will remove this blurriness here for a while.
18:20And I will increase the word opacity here.
18:25So in this way, I have created an environment on the back side
18:28whose light is falling on my globe.
18:31I will come back to my node here.
18:34I will disconnect this BSDF from here for a while.
18:38And I will take another one here,
18:41whose name is here or I can take it directly from here too.
18:44Whose name is my Principle BSDF.
18:47Now I have two BSDFs here.
18:49One is my Diffuse BSDF here.
18:52The other one is my Principle BSDF here.
18:54If you look here,
18:56if I want to connect both of them together with the surface,
19:00as soon as I connect it here,
19:02you will see that my previous one will be disconnected.
19:05This one will be connected.
19:06If I try to connect it here again,
19:09my previous one will be disconnected.
19:12And this one will be connected.
19:13This means that with one node,
19:16I can use only one BSDF here.
19:19Like the problem here is that
19:21if I want to connect both Diffuse and Principle here with the surface,
19:25then I cannot connect it directly here.
19:27For this, I get one more option,
19:30whose name is my Add Shader.
19:32So the first one is my Add Shader.
19:34As soon as I connect it,
19:36you will see that it will come to me here.
19:38If you don't want to take it from here,
19:40then press the Shift A button directly.
19:42Search for Add Shader.
19:44You can also take it from here.
19:48So what this will do for me is that
19:50I can connect the surface here with this one.
19:53And if I want to connect these two with this one,
19:56then these two shaders will be easily connected with it.
20:00Like this.
20:02For now, I will remove Diffuse.
20:04And only one shader is connected here,
20:06Principle BSDF.
20:08If I want to bring shine to it,
20:10if I want to make its environment reflect,
20:13then for that, I have to make it Metallic.
20:16And I will make the Metallic option from 0 to 1 here.
20:19And I will remove its roughness here.
20:22I will take it to 0.
20:24So you will see that its previous environment
20:26is now starting to reflect in it.
20:28And all the things around it in my material
20:31will start to reflect in it.
20:34So whenever you make water or make a glass,
20:37you can make it very easily in this way.
20:39Now you have to pay special attention to one thing.
20:42Whatever environment will be around it,
20:44it will reflect in it.
20:46If I try to show it in the render,
20:48then there is nothing all around here.
20:51That's why I can't see anything here.
20:53So there should be something all around it.
20:56Only then it will reflect in it.
20:58Now let's find out Diffuse.
21:00How will Diffuse work in it?
21:02Now the reflection that I have used in it,
21:05if I want to reduce its reflection a little bit,
21:08then I can use Diffuse in it.
21:10And as soon as I connect it here in Diffuse,
21:14with the surface,
21:16you will see that my reflection has reduced here.
21:19If you want to change the color,
21:21you can also change the color.
21:23If you want to keep it white,
21:25you can keep it white in this way.
21:27So here you saw how I connected
21:29these two with the help of Add Shader.
21:31And after connecting,
21:33I got the output like this.
21:35In Add Shader,
21:37we don't have any option here
21:39with which we can increase or decrease
21:41Diffuse or Principle in it.
21:43But if you want to increase
21:45the Diffuse option in it,
21:47then for that,
21:49I will remove it from here.
21:51And like Add Shader,
21:53we have another shader here
21:55whose name is Mix Shader.
21:57As soon as I use it here,
22:01I get to connect these two
22:03at the bottom of the screen
22:05with the help of Add Shader.
22:07I can connect them like this
22:09with the help of which
22:11I will get the output in Add Shader.
22:13And if I want to increase
22:15or decrease someone's effect in it,
22:17let's say I want to increase Diffuse,
22:19then I have connected Diffuse
22:21at the bottom of the screen.
22:23The more I pull it forward,
22:25the more Diffuse will increase.
22:27And you can see the transparency
22:29is reduced here.
22:31So this is how my Diffuse works here.
22:33If I want to reduce Diffuse,
22:35then I will pull it back here
22:37and its Diffuse or Reflection
22:39will decrease here.
22:41And if I want to change the color in it,
22:43then I can change the color
22:45from here.
22:47So if you want to use Diffuse
22:49in water, glass or anywhere,
22:51then you can use it with the help of Mix Shader.
22:53So you saw how our Diffuse
22:55works here.
22:57We can reduce
22:59the reflection of the material
23:01as much as we want.
23:03The meaning of Diffuse in reality
23:05is that it spreads
23:07the reflection or light
23:09from all sides.
23:11The more we increase
23:13the Diffuse,
23:15the less the light
23:17will fall on it.
23:19Let me show you another small example.
23:21I will press Shift A
23:23and select Monkey.
23:25I will show you the front view.
23:27It will look something like this.
23:29The light is falling
23:31on the surface.
23:33First of all, I will select
23:35a material in this Monkey.
23:37I can create a material by clicking on New
23:39or I can create a material directly
23:41in the Node option.
23:43This is how my material will be created.
23:45I will give it a color like this.
23:47For now, I will remove it
23:49and take the Diffuse option
23:51instead of it.
23:53I will give it a color like this.
23:55To show the effect of light,
23:57let me tell you that
23:59if there is any light effect
24:01of Diffuse,
24:03then it will be visible
24:05only in Cycle.
24:07If I reduce the Roughness
24:09of Diffuse,
24:11you will see that
24:13the light has increased.
24:15The more I increase the Roughness,
24:17the less the light will fall on it.
24:19The more I reduce the Roughness,
24:21the less the light will fall on it.
24:23This is how
24:25Diffuse works.
24:27I hope you understood
24:29Diffuse well.
24:31Practically, we will do a lot of
24:33modeling work when we understand
24:35Diffuse well.
24:37Here you saw that we learned
24:39about two BSDFs, Anisotropy BSDF
24:41and Diffuse BSDF.
24:43Along with this, we also learned
24:45about Add Shader and Mix Shader.
24:47First of all, we will
24:49cover all the BSDFs.
24:51Along with that,
24:53we will cover the remaining BSDFs.
24:55Today's video is
24:57quite long.
24:59I hope you understood
25:01the two BSDFs.
25:03Anisotropy BSDF and
25:05Diffuse BSDF.
25:07See you in the next video.
25:09In the next video, we will see
25:11how to make Glass.
25:13Whatever I am explaining to you,
25:15Anisotropy, Diffuse,
25:17Glass or Glossy,
25:19you will get all these options
25:21in different types of software.
25:23In every software,
25:25they work on the same concept.
25:27Do practice it.
25:29Without practice,
25:31you will never be able to remember it.
25:33Once you practice it,
25:35it will fit in your mind.
25:37For now, we will stop here.
25:39See you in the next video.
25:41Along with the next BSDF
25:43and new concepts.
25:45Till then,
25:47Goodbye.
