0:00Hello everyone, how is everyone doing?
0:01My name is Deepak and welcome all of
0:03you to the Deepak Rafi Hindi YouTube
0:04channel. So first of all, I want to
0:05apologize to all of you. I haven't been
0:07active on YouTube for quite a few days.
0:09And there are many reasons, some
0:10personal, some other things. So, I
0:12apologize for that and I am trying to
0:14keep things consistent now. And I have
0:16received requests for many topics. So,
0:18it will be my endeavor to cover all
0:20those topics here. And all the previous
0:23part one, part two videos we have made,
0:26we will continue them, and along with
0:28that, videos have started being
0:30uploaded to our Blender Basic to
0:32Advanced new version course for our
0:34membership as well. So if anyone wants
0:36to join there, please do join. The fee
0:39there is only ₹ 150. So let's go guys
0:41, without any delay, let's start
0:43today's video. In today's video, we are
0:45going to talk about how we can create
0:47facial expressions in Blender.
0:50Basically, suppose you have any model
0:52and you want to customize it, create
0:55facial expressions, lip-syncing,
0:57blinking, and all that in your own way,
0:59then how can you do it? So without any
1:02delay, let's start today's video. And
1:05the second thing guys, if any of you
1:07need any type of 3D model, we have all
1:08models available. You can contact us on
1:11the number given below. So without any
1:13delay, let's start today's video.
1:15Alright guys, for now, first of all, I
1:17have Chintu's facial rig, which I have
1:18done separately. Videos for this will
1:20also be coming very soon. We will
1:22discuss this one later. For now, I will
1:24hide it because it has been created
1:25with the help of an add-on. So I will
1:27tell you about this later. Right now,
1:29you can see we have already created a
1:31shape key on this, which is basically
1:32for its lip-syncing. So I am going to
1:34tell you how you can also do such great
1:36lip-syncing. So without any delay,
1:38let's start today's work. So first of
1:42all guys, see, the model you have,
1:43basically if you look at it carefully,
1:44you need to pay a lot of attention to
1:45two or three things in it. The first
1:48thing is that, look, this model of
1:49yours should be an entirely single
1:51object. If it is not a single object,
1:53it is possible that your lip-syncing
1:55may not look that good. But do you know
1:57what the problem is sometimes? The
1:59problem is not whether it is a single
2:00object or not. Sometimes it happens,
2:02let's assume it is a single object. Now
2:03, let's say I have created its
2:05lip-syncing. So, in that, I also need
2:07to move its teeth. I also need to move
2:09its tongue, so how will I move it? For
2:12that, I have already found a very good
2:13way, so to speak. In that way, you can
2:16do it very perfectly. So, first of all,
2:19I will do one thing: I will join the
2:21neck that I had detached from here so
2:23that everything looks excellent.
2:25Alright. Okay? Now it looks right. All
2:28good. Perfect. So, first of all, I will
2:30tell you what I have done in this. If
2:33you come here into my Object Data
2:35Properties, you will see that if you
2:37select "teeth bottom," the bottom teeth
2:39are selected. And if I select this, the
2:42top teeth are selected. I will show you
2:45by selecting this mesh and pressing
2:48Ctrl + H to hide it, then you will see
2:51I have already made these, the bottom
2:54and the top, into what already? I have
2:58kept them created in vertex groups. Now
2:59, what is the reason for this? Why have
3:01I created vertex groups? The reason is
3:03that this makes it easier for us to
3:05select things. So now I will tell you
3:07how. For now, first I will turn off my
3:09X-ray mode and remove whatever shape
3:11keys are applied to it. Whenever you
3:14see, whenever you want to do
3:15lip-syncing on any object or any
3:16character, it doesn't matter if it's
3:18human or non-human. It makes no
3:20difference. So what do you need to do?
3:21You just need to come into your Object
3:23Data Properties. And after coming into
3:25the Object Data Properties, you just
3:27need to click on the Shape Keys section
3:29here and add your first key. So, our
3:32first key is our basis key. What is a
3:34basis key? Basically, it is what holds
3:37our basic shape. You have to keep this
3:39in mind. It holds our basic shape. So,
3:42in that, you will see that you don't
3:44even get many options here. Friends,
3:46when you click on 'New' here, you will
3:48see 'Key 1' written. Yes guys, this is
3:50'Key 1' where we will basically perform
3:53the deformation, and whatever
3:54deformation we do to this character, it
3:57will record it as is, and then we can
3:59use it in any way. So, what will I do
4:01first? I will double-click it to rename
4:04it. Let's say I name it 'Talking'.
4:07Let's use 'Talking' instead of 'Lipsync
4:09'. I have set it to 'Talking'. And
4:12after that, I will go into its Edit
4:13Mode. Pressing the Tab key. You will
4:15notice it lifting up slightly. So, what
4:17is the reason for it lifting up? Always
4:20keep one thing in mind: if there is any
4:22bone or armature inside your object, it
4:25will slightly deform from its position.
4:28So, if you don't want your object to
4:30move from one place to another, you can
4:33turn off all the armatures. For now, it
4:35doesn't really matter. So, I am not
4:37worrying about it, and I will press Tab
4:39. It went up a little in Edit Mode.
4:41That's not a problem. Then, what will I
4:43do first? Basically, I will press 3 to
4:45go into Face Mode. Or you can go there
4:48manually. Then I selected this part and
4:50this part. Now, as I try to move it by
4:53pressing 'G', it is very difficult to
4:55move this mesh. But if I go up here, we
4:58have 'Proportional Editing'. If I turn
5:01it on, you will see that I can pull it
5:03easily. Now, with the scroll wheel, I
5:05can adjust the Proportional Editing
5:07size. But there is still a big problem
5:09here. The problem is that it is pulling
5:11like this. In this way. Now, what
5:12should be done about this? Why is this
5:14happening? Because, look, there are two
5:16types of Proportional Editing. One is
5:18Normal Proportional Editing, and the
5:20other is Connected Only Proportional
5:21Editing. So, what is it currently set
5:23to? It is set to 'Normal'. If I go into
5:26its settings and click on 'Connected
5:28Only', then only the parts connected to
5:30this face will move. The whole thing
5:33doesn't move. So now, if I press 'G'
5:35and 'Z' to move it slightly downward,
5:37you will see that its lips are opening
5:39quite nicely. That looks awesome, by
5:41the way. So, I will open it from the
5:43bottom here as well. After selecting it
5:45like this, I’ll press G and open it
5:47upwards too. Something like this. Now,
5:50if I exit edit mode, you’ll see that
5:53when I move the value slider up and
5:55down, the mouth opens. There’s no
5:58issue, but the teeth aren't moving,
6:00which looks very strange. Now, what
6:02will I do? I'll go back into edit mode
6:04by pressing Tab. And you’ll see
6:06it’s quite difficult to select all
6:08the teeth here. And because of this, I
6:11had already created a set in the vertex
6:14group beforehand. Now, what will I do?
6:17I’ll select the top teeth and press G
6:20and Z to move them slightly upward.
6:23Similarly, I will select the bottom
6:25ones. Select them. After that, I’ll
6:27press G and Z to move them slightly
6:28downward. And the tongue inside, which
6:31should have been mixed with it but
6:33isn't. But now you’ll see, when I
6:36move it, look how smoothly it’s
6:38moving. If you still find any issues or
6:42problems, you can move things slightly
6:43to make them look better. It’s
6:46totally up to you how you want things
6:49to look. Here we go. So, I will lift it
6:52up just a little bit. Something like
6:55that. And as soon as you are done with
6:56proportional editing, turn it off
6:58immediately. I want the top teeth to be
7:00slightly visible. So, I’ll press G
7:02and Z. You can see the top teeth are
7:04now visible. And now here we go. Here
7:08we go. It’s looking quite great.
7:10It’s looking pretty good. And this is
7:12what we want, by the way. Alright. So,
7:15I think you have understood how we
7:17basically create the talking animation.
7:19Now, it doesn't matter which character
7:21you have, it makes no difference. You
7:23just have to use the process I have
7:26explained. Understood? So, I hope you
7:28understood how this works. This is how
7:31we can create lip-syncing for any
7:33object without any issues or trouble.
7:35Okay? Along with that, suppose I create
7:38a new one here. And then I will name it
7:42'Blink'. For example, I blinked here,
7:45and after blinking, now you will see,
7:47when I go back into its Edit Mode, here
7:49you can see we have this type of mesh.
7:53And along with this, we also have to
7:54keep in mind that its eyes are
7:56protruding slightly, so the rig we make
7:58for this should be better. So what I
8:02will do is, first I will select all
8:04these eyebrow faces, and by pressing
8:06Shift + H, I will hide everything else.
8:10Only these three remain. And by
8:11selecting these three, I will go to the
8:13modifier section, go to all tabs, and
8:15what will I do for all of these? What
8:16do you call it? I will turn off the
8:18armature modifier. The benefit of this
8:19for me will be that when I go into Edit
8:21Mode, it won't move. It will stay in
8:23its place. For now, I don't need the
8:24eyebrows either. So I will hide them.
8:26Just I need only this one. So what do I
8:28have to do? Go here and make sure you
8:30are inside the blink one. Not inside
8:32the talking one. So you will go into
8:34Edit Mode and select this entire
8:35section. And if your model is fully
8:39symmetrical, meaning both sides are the
8:41same, then you can turn on this X here.
8:45So if you work on one side, it will
8:46automatically start working on the
8:48other side. So my model is already
8:50symmetrical, so I will use this, and
8:52after that, by pressing S and then Z, I
8:54will set it like this, first in this
8:56way. Then I will bring it out a little.
8:59That is super important somehow, in
9:01some way, like this. And that looks
9:03awesome by the way. And look, a very
9:05good feature of Shape Key is that you
9:07can modify it however you want
9:08according to your needs. And this is
9:11what I love about the Shape Key. I
9:13really like it, to be honest. So this
9:15is the best thing about it. If, let's
9:18say, I scale it a little bit here.
9:21Let's do one thing. Let's set a bit of
9:22control. A little more, so I made it
9:25slightly smaller on purpose. A little
9:27more, a little more, just keep it this
9:28much. Now I will manually select it
9:31myself and bring it down slightly. Like
9:34this, so what is happening with this?
9:36Basically, I am able to maintain the
9:38shapes of my eyes according to my
9:40preference. Look at this, this is what
9:42we want. This is the beauty of shape
9:46keys, that we can modify or move them
9:48however we want. And here we go. You
9:52will see that it takes a little bit of
9:54effort, but it is a one-time task.
9:56It’s a one-time job. Once you have
9:58done this. Then after that, you won't
10:00need to put much effort into it. So
10:03that we have to understand every time.
10:06So here we go. For now, this sharpness
10:10looks a bit off, so I will push it
10:11inward so it gets fixed. And I will
10:14push this one inward a little bit too.
10:16Something like that. And I need to
10:17remove the sharpness. So I need to
10:19bring this part out a little bit to
10:22create volume. And here we go. We have
10:26created a little volume. So you just
10:29have to pay attention to these things.
10:31Other than that, there is no such
10:32problem or trouble. And now you will
10:34see that the blink is working properly.
10:38If you feel that something is wrong,
10:40just fix it wherever it seems off. Okay
10:42. Right. Press G twice. Press G twice
10:45to move it back a bit. Press G twice to
10:47move it back a bit. Press G twice to
10:49move it back a bit. A little bit back,
10:51we will push this part inward slightly.
10:54It will look better with a bit of
10:56smoothness. Here we go. So wherever you
11:00feel that things don't look right. And
11:02here, it is totally a matter of time.
11:05It is all about time here, how you have
11:07to fix it or not. So you have to
11:10totally understand that. Alright? Now,
11:12let's talk about the eyebrows. So watch
11:14carefully how to do the eyebrows. Let's
11:15select both of them. We will press
11:17Shift again. Now look, first I will
11:19select the eyebrows, and since I have
11:21already selected both together, I will
11:23press P and separate by loose parts, so
11:25both will be separate. This is separate
11:27, and this is separate. Now you have to
11:29play the game very smartly here. You
11:31have to go into Edit Mode. Press A to
11:33select your eyebrows. After that, you
11:35have to select your eyes. And here you
11:37will see that when I go into edit mode,
11:39these eyes automatically close. So,
11:41what do you just need to do? You need
11:42to Ctrl + J this with this. And when
11:45should you do Ctrl + J? Select your
11:46eyebrow, and before that, select it in
11:49edit mode. Why am I doing this? There
11:51is a reason for it. I will select the
11:52eyebrow first. Then I will select this.
11:54I will press Ctrl + J. Now, as soon as
11:56I pressed Ctrl + J, you will see that
11:58the eyebrow has vanished somewhere. It
12:00has disappeared somewhere. Somehow you
12:02will see. But if you look, it is right
12:04there. Why did this happen? Because
12:06look, the texture that was inside it
12:08basically disappeared from it. So, we
12:09don't care about that. What do we need
12:11to do? Just take it out. This is a very
12:13large eyebrow, basically, and we need
12:15to bring it down. And what do we need
12:16to do with it? Scale it in this way.
12:19Because the texture that is basically
12:21inside it, I will bring that back later
12:23. But first, I need to set it according
12:25to the eyes. Something like this, and
12:28it doesn't even have to be set
12:29perfectly. Roughly, you have to set it,
12:31and you will see that your work is done
12:33. You won't even notice. Okay? But now,
12:35we need to apply the texture to it. So,
12:37we will go here into the materials, and
12:39these are the baby eyelashes. We need
12:40to assign this. Now, as you go to
12:42assign it, you will see that nothing is
12:44visible here. This is because I have
12:46joined it with this. So, the UV of your
12:48eyebrow has basically been shifted. So,
12:51what will we do? We will bring the
12:54eyelashes out from here. There they are
12:56. Now, I will select this. One second,
13:01let's look at it in the front view and
13:02top view once. I will normalize
13:05whatever I have here. I will press U
13:08and do "Project from View". So, my
13:09eyelashes have appeared. I will select
13:11it by pressing A, something like this,
13:13and you will see that the eyelashes
13:15have started appearing here. So, let me
13:17try to unwrap it normally once first,
13:20and angle-based...yes, angle-based is
13:22coming out better. So, I placed it
13:25somewhere here and set it somewhere
13:27here. I think it has flipped. Down
13:30there, like that, for now, I have
13:33roughly set it, something like this.
13:38And here we go, so you're getting some
13:40issues on the sides, like this. So now
13:44the texturing part remains, but I've
13:46shown you one already because the video
13:48is already getting too long, so I won't
13:50show the second one. So here is our
13:52eyebrow, and now you will see, as soon
13:53as I select it, look at its average,
13:55it's moving perfectly with it. So this
13:57is how we can do it. And if you want to
13:59make it even better, I mean this thing,
14:01then you will have to move it up a
14:03little bit like this. And look, its
14:05averages have become perfect. And here
14:07we go. Look at this. So these are going
14:10along with it. And basically, our
14:11blinking is also perfect now. One
14:13second, let me turn this off. Look at
14:16this. Okay? Now you might ask why it
14:18doesn't have that finishing touch?
14:19Because this finishing was still left
14:21to be done as we had already started
14:23working on the texture. We couldn't see
14:25it. And now that we can see it, we can
14:27set it here with a proper finish. There
14:30is no issue or problem with that. Yes,
14:32look, make it as perfect as you want to
14:36make it here. There is no such issue or
14:39problem. And here we go, it's working
14:42perfectly. Got it. So the second one
14:44will also be something like this. So
14:47alright guys, in this video we learned
14:49how we can do lip-sync for any
14:51character and also how to do blinking.
14:53So I hope guys you understood how this
14:56is done. And if you liked this video,
