Today I will give you a commentary on Angular XY deformation of hair. I will give three examples this time. This is for advanced users. This is the MEGURI I've been making all along. I have prepared three types of examples, one for beginners, one for intermediate users, and one for myself. I didn't make intermediate and beginner examples in time, sorry. A beginner is someone who knows the basics of how to use Live2D and how to rig. This is intermediate. It is a state where you can make a low cost model and you want to improve, but you don't know how. I'm talking about the level of seniors who can accept requests from companies. I'll show you advanced moves. This is a moving face. I have finished this production, so I got permission from the client to use this. This MEGURI is working. This is an intermediate move. Intermediate students are at a level where they can receive requests for personal work, but they lack a three-dimensional effect. There is no sense of incongruity when it is a model of this range of motion. It's moving big. It's a movement you often see in Live2D. When it moves a lot, the processing becomes a concern. It works well with low range of motion. This is a novice move. This is a common movement in Live2D. This is not bad. Live2D's movement is good, but it feels flat. This is moving by sliding parts. I will tell you how you can level up from here to intermediate and advanced. I will explain to beginners what techniques are missing. This is a big deformer with a swing deformer for the bangs. I am using this to move angle Y and angle X. This is the same for any model. This is planar. This is useless because the original shape does not change when facing left and right. This is a round shape, but it has the impression of just being slid. Place your finger on the top of your head. This is the top of the head. The bangs, horizontal paper, and back hair grow from there. The trichomes should not move. This is due to the movement of the trichomes, and the position of the triceps on the back of the head is displaced and separated. It feels like the parts are moving. Some people know how to round the trichomes. This is common for beginners. Some people end up with hair attached to their trichomes. Use the swirl as the starting point. The swirls no longer move. This is a problem. You can see this when you see it. It has a flattened forehead. touch your forehead The forehead is round. The forehead is protruding. It shrinks from there to the eyes and cheeks. It has a dent at the corner of the eye, a bulge at the cheek, and a chin. The forehead is protruding, but this one is concave. I see this rig a lot. I can think of this cause. The default state of the deformer is split into two. If you move it in this state, the center will be the base point and it will bend straight from the forehead. This is bad. how do i do this? Add roundness to this by moving the Bezier handle on the green bar of the Bezier curve. This makes sense once you understand how to use Bezier handles. This looks better now. Bezier division of this quadrant is difficult. I have 4 splits. This is easy to move. It's straight here, so it's bad. Please fix this. Have you ever touched a type of Bezier editing? I explained this on camera so some of you know. If you set this to "Smooth 3", it will be deformed while drawing the curve, so it will be easy to transform. There are multiple ways to do this. Please do not flatten this forehead. I use my favorite Deformation brush here. This selects the horizontal and bangs together and I can move them. Please pay attention to the thickness of the side hair on both sides. This hasn't changed. Since the thickness of both sides has not changed, there is no feeling that it is wrapped around the back. This is bad. This is good if you shrink the back. I processed the Deformer, but sometimes I adjust it with Artmesh. This changed the stereoscopic feeling. Please pay attention to the back of the hair. You can understand this by imagining a cylinder. This is because the back part looks shorter from the front. There is a sense of incongruity if the thickness does not change. The bangs are wrapped around the skull, so please change this thickness. I will thicken this inside. This differs in the roundness of the forehead. This has a different three-dimensional effect compared to the unprocessed one. This is the only operation, but there are changes. Deformers may Inversion of movement. This is an example. MEGURI's hair is asymmetrical. This may move strangely when facing the other side, so adjustment is required. I use this while Inversion of movement. This works better than the first. This is an angle X motion. What about angle Y movement? This angle Y move is a move that beginners fail. This is the face moving up, so the hair is curly. This does not change the relationship between the back of the head and the bangs. Do you know that the back of the head hasn't changed? When you look up, lower the back of your head. This looks flat. Just lower it to change it. Objects in front move and objects in the back do not. It moves in the opposite direction of the object in front of it. When the front face and bangs are facing up, the back of the head moves in the opposite direction. Look at the eye part of this face. This is uncomfortable with the bangs. This face is the same as the one I'm editing, so it's well deformed. The eyes arc upward, but the bangs do not move. This is bad. Since the head is round, it must move in an arc when moving up and down. This is WIG. Hair looks like a WIG if it doesn't move well. It looks like a WIG because it doesn't grow from the top of the head. In order to grow hair on a cute model, please add a three-dimensional effect. This one is facing up with the hair on the forehead. Some people divide the lateral hair deformer into left and right, but I don't do that. You can do this better if you don't separate them. Can you see that the three-dimensional effect has changed? It hasn't changed much. A small adjustment makes all the difference. There is no excuse not to do this. This is changing. I want to put my hair on her cheek. This is the side hair. Please put your hair on this cheek. She has hair on her cheeks. Upward is easy because it deforms along the curved surface. This downward direction is difficult. This is the same for me, but there are many people who are staggering this. It has a flat feel. Please make this bangs arc-shaped. If you look down, you can see the head part better. This allows you to see the upper part that was not visible from the front. Please transform it so that the upper part can be seen well. This is the Bezier division number of the Bezier curve. This is the green dot. This can be easily transformed by changing the number of divisions. I fix her hair This added dimension to her. Don't pull her hair too short. It hangs down due to gravity. i will fix this. This is no longer a planar up-down deformation. Let me also explain how to deform diagonally. It is difficult to transform diagonally. First press CTRL and 4. Auto-organize the four corner forms. If you simply auto-organize this. It makes the back hair go very high up. So first lower this like this. and raise this Please bring this down. Please raise this. Raise this on the other side. Please bring this down. Please raise this. Please bring this down. This is a rough transformation. About when this is oblique. Many people are flat here. It's cute if you bulge it out a bit. This will inevitably be stretched when tilted. It's straight here. It's cute if you make it round here. There is a sense of incongruity that this is straight. It's good to use a Deformation brush in such a case, so I use it frequently. It's straight here too, right? Regarding when she looks diagonally. It may not go well just by multiplying. This is a lot better than it started, right? Has anyone noticed this? It's about moving her face sideways like this when she looks up and down. Can you see the movement of this bouncing a little bit? This is a little less smooth. In such a case, please put "extended interpolation" in angle X. I have also explained this in NOTE. I put 3 points in the extended interpolation. 5 is too many, so I put 3 in. This will interpolate the movement here. This will interpolate on the curve, so the movement will be very smooth. This is what it looks like. The bangs and sides of this hair are beautiful. However, this does not come with back hair. This is a little difficult for beginners. Side hair and bangs of this are good. Adjusting the back hair is very difficult. So I'm going to speak for intermediates here. Here's an explanation for the intermediate level. I talked about this earlier. This is the story of someone who is very good at transforming this DEFORMER. I'm doing my best to move the hair behind this. This is slightly moving the hair in this part. However, the knot behind this is not moving together at all. An illusion tricks the brain into thinking this is moving. However, if you look closely at this, it feels strange. The side hair is moving very beautifully. It's like this. The hard part is the other side. It's just about the parts that were there originally. It may be impossible to move. It's like this. I think that they are doing their best to move things in this way. However, the shadow here suddenly appears. Only the appearance of shadows has not been fixed. This movement looks so beautiful, doesn't it? It's like this. Again, this side is a little strange. It moves slightly, but I'm still concerned about this gap. I often see models like this. This makes the bangs and side hair move very beautifully. But the back hair is not moving together. I see models like this very often. I am a rigger. So I look closely at the hair behind the picture so it bothers me. Ordinary people watching VTuber don't care about that. It is good to say that this is also good. This is the only thing that moves, so I don't care that much. For low excursion models, that's perfectly fine. However, this is a rig that you can see shadows when you look closely. Let's take a look at the advanced version. I can't explain much because the intermediate level is intermediate. You can become an intermediate player if you do the transformations of the beginner's edition properly. Intermediate students have a part that can't be done by itself. It's about the difference between seniors. Seniors are like this. Do you know that side hair is solid? This is advanced. Can you see the back hair of this completely wrapped around her body? I made this while consulting with Pirorikin Sensei . This is completely different, right? About how to make this. I am forced to add various drawings. Look over here. I haven't drawn much on this side. this is about what i did. I didn't do anything like this for beginners' drawings. If you move the picture in the intermediate level, it will move like this. I forced myself to draw a lot of dots along this shadow. This is stretched using DEFORMER. Here it is. This is good because you can do it without adding drawings. It's about what I did as a senior. I moved Artmesh like this. I am forcing this to work. I'm taking advantage of the recently announced feature. This is what it looks like without the parts. This is what it looks like with the parts. Can you see this is a little brighter? Here's what I did. I prepared a parts with a slightly lighter hair color like this. I am not adding to the drawing. If you add a darker color to the "screen color" here, her hair color will be slightly lighter than the original color. Her side hair is light. So if you don't make a solid connection with that, it's unnatural. It's like this. It will be side hair, back hair, front and back. It's about making it seamless. So I made this side a little brighter. Using such techniques this is rounded. I also move the part where the hair is tied. Beginners are just moving it and it looks like this. Intermediate players move this knot accordingly, can you see it? It's part of this vortex. Here it is just sliding as it is. It's like this. This is how I make everything look three-dimensional. Here it is. This has a three-dimensional effect. Pirorikin Sensei separated a lot of this. This is clearly divided into front and back. Thank you for that. So I hit the mesh like this. And this is how I move. Also, can you see how DANGO gets a little darker when you turn it this way? about the reason for this. This is a little brighter to match the color of the side hair. When you turn to the side, this leaves the side hair. This is the original color of this. Can you see that it looks a little floating? I darkened it a little to match the color of the hair behind the shadow. It's like this. I think this makes it easier to see this here. I am really grateful that such things can be easily done with "Screen Color" and "Multiply Color". Cubism4.2 is really convenient. I made the ribbon like this to match it. I give it a three-dimensional effect. All of this is also attached with Artmesh. The BLEND SHAPE I talked about last time is very useful. So I stopped using DEFORMER. All the wiggling movements in this one I added with BLEND SHAPE. At the angle XY I'm hitting a point directly with Artmesh. The way I make things has changed. This is how I do it now. It's enough to get to this point. However, if you want to receive a request for work from a larger company or office. People will think you're amazing if you can do this. what about the other side? I said this earlier. It was difficult with just the original parts. With Pirorikin Sensei permission, I added it. I drew it completely from scratch. It's like this. This is still an advantage for those who can draw illustrations. I made the drawing parts. It's about how I do this. Once in this state, add an image like this. Export the image and move it to PHOTOSHOP. And make a new parts there. Please move it here. Please shrink this with the front here as the default. Please shorten it like this. See that one dot in the middle here? Try to reach 100% at this halfway point. 0% when facing forward. This is my pride. The original picture is justice. The front picture drawn by the illustrator is justice. I don't want to change it too much. So I try not to show it then. It's because this state is the cutest. So it will be displayed when you turn a little to the side from that state. Here it is displayed by switching transparency. It's like this. Her original hair looks like this. It's dark because it's hidden behind. I am also drawing here. I'm trying to make it brighter when it's turned sideways like this. It's like this. It's about when you point it up or down. . I also added the swirling part here. This is also 0% when she looks up. It appears slowly. If you switch it, you may feel a sense of incongruity here. It's surprisingly hard to understand when it changes seamlessly. It looks nice. I paint. I don't want to paint So I have a painter draw a picture and I move it. Thank you. However, when I make the parts, I make them while consulting with the artist. If you can draw everything yourself, you can easily add parts like this. It certainly comes in handy. It's about when you can't draw. I want to respect the intention of the illustrator. So for example I provisionally draw it myself. For the time being, I will add here and here. I will send a video to the illustrator to show that I have added this parts. I will tell you that I added parts here and here. If the illustrator adds their own, I will replace it. Some illustrators don't care about that. Of course, there are illustrators who want to add their own drawings. In that case, I will ask the illustrator to send me what they added. and i will replace it. So even if you can't draw a picture, you can ask an illustrator to draw more. I do it that way If you can do that, the three-dimensional effect of this hair will change a lot. It's a small detail that you probably wouldn't notice. This is about the difference between beginner and intermediate. That's the air intake I also have. That's the part that's shaded and rounded here. I want you to see here of CARD CAPTORS SAKURA. This is the same for beginner and intermediate level. Do you know that the shape here has changed in the advanced version? Actually, I also finely point Artmesh here and move it. I separate them like this: I separate it in the back and in the back. I create a three-dimensional effect by dividing this part. The same goes for the top and bottom of this. This is a wrap around detail. After all, “God is in the details”. This place is also like this. After all, the three-dimensional feeling is different. And for example about hair that is a little bouncing. It's about different colors, mesh, and short floating hair. It's about the case where the hair is just one bunch curled up. I move it a little more like this. I make another DEFORMER and run it a little more. I didn't move the bottom shadow much. That way you can distinguish between before and after. Can you see that only the bouncing hair here is in front? If you have this, you will feel very three-dimensional. It clearly distinguishes between before and after. Without it it looks like this. This is cute with this. If it's an intermediate level, it's like this. Even this is cute. When such a three-dimensional effect is added here, it looks like this. Actually, I have divided everything here as well. When you turn it sideways, this is the front, so shrink it a little. On the contrary, I try to look good here. And so is the back and front here. In the previous video, I said, "It's good to divide this into parts." I use it like this. After all, I think that the three-dimensional feeling changes greatly when there is it. It is about important things in Live2D. That is the "appearance when moving". That's pretty important. So even if you stop the movement, these will not look much different to you. It's like this. Especially the side hair of this does not understand the difference. It's like this. But after all, if you move the picture, the three-dimensional effect of the side hair is different. It looks totally different for beginner and advanced. I cherish the three-dimensional feeling when moving. I also change my hair here. This is also like this because I separate all parts. This face is made by doing all these things. That's how it is.
