Mouth forms || Live2D rigging ||

hello hello everyone!! Since I've finished the art and working on rigging I thought along the way I could show off what I do, so I'll make posts going over rigging and things I do to make my models :3 in case anyone desires explanations or help

This one will be going over how I do the mouth forms

The mouth in particular I make a make two lips, upper lip line with skin, then a lower lip (you can add flesh teeth ontop if you so choose) top main teeth, with fangs same to the bottom, then back molars to make it more 3 dimensional for rigging! Then tongue, inside of the mouth and back of the throat.

Art is shown below on the right for easier seeing

Once imported I make the parameters directly on the art layer without using deformers, the lips are controlled by a deform path to make the editing of the lips easier to control! Also deform paths mostly primarily work on the art layer in live2d directly!

Then we get to the specifics of mouth forms so I'll explain simply

Mouth form- is tracking your smile

Mouth open- how far you open your mouth

The left number on the showcase bellow is my mouth form, and the right is my mouth open

Of course you want 1, 1 to be an open mouthed smile

I have noticed -1 (mouth form) in vtube studio is where it places the tracking for when you make an O with your mouth, so you'd want your more triangular/circular mouth there, then have the more open mouth transition on -.5 and 0

That will making the mouth tracking look more natural

Some people will add a small tongue click in the mouth open a parameter (.3) to seem like the character is making a L sound when speaking, although this is personal preference

Each frame has to be made individually (each point shown intersecting is one frame) the program will do the in-betweens... You will have to edit each piece (the teeth, to tongue and back of the mouth to lips) to make it track properly

I also now adays add jaw movement to make it seem like it's speaking then a little bit of a nose push up (scrunch) when the mouth is fully open (this is just my personal preference)

Since you've edited everything on the art layers later on you can add more 3d effect with deformers on top of the art layers but that is another explanation I'll go into later!

Thank you all so much for reading and I hope this will help someone I'll probably continue to post about model work while I make this new model!

Did y'all know that Gecko is a god at separation? Even the simplest artstyles and models can benefit from good understanding of rigging and Live2D separation ^^

Brow + Head tilt reactive ears || Live2D model tutorial/tips

Hello hello today imma bring a small new explanation this is one I've seen alot in more fancy models but never seen like a tutorial or explanation (hell finding out how from better rig makers was like pulling teeth)

what I'm talking about is having the ears on a character or pieces react to the eyebrows plus the head tilt all in one

So let's get started :3

I showed above what I did to make the ears and wings on this new model react to both movements but I'll also explain for those curious who would prefer to read over just looking and copying

I'll be explaining it for what I have since I use a web camera this is more simplified but can be used for more parameters

You'll need at least 4 base parameters

Your movements which in my case one brow movement (the tracking your brow up and down) and angle z (head tilt)

Then your ear/item movement on each side (have your left and right seperate-) you can seperate each ear/item like I did (such as having my wings and ears seperate)

I have a deform labeling what it is then the base parameters movement ontop labeled flop as my movement, to make the movement easier without rotation deformers (as these can be very picky)

You can hold ctrl (control) on your keyboard and move the deformer/red box

I place it near the base of the ear/item then rotate it by holding the corner giving me the option to rotate back and forth, you can then apply the end frames as how far you want

Please note deformers like this when rotated and pushed to far without the proper techniques will squish and distort the image/art, so do not push the rotation very far

Once you have all your movements done you can go into your physics settings/physics window which is where you'll make this movement happen, this is also the same place any physics are done (such as bouncy hair to eye effects etc)

next to duplicate press add to make a new physics group and label this group as whatever side of ear movement your doing, for this I'll be explaining the right as the one you see

Your input settings which I'm tabbed on is where your movement is, basically what is the beggining movement to cause the effect, which in this case what are my ear movements tracking??

For me in particular I have angle Z and browL Y, so you press add above the both then add those two parameters in, please note effectiveness can only react a max of 100 overall per angle (or position) so I've split it down an even 50/50

Next is normalization of input, this is what you need to edit to make the ears react the way they do

If you do not edit this your ears will react like a normal physic and not move the way you want it to

Since our type of input is angle we are editing the angle option in this, and setting it to minimum of -90 and maximum of 90

Normalization of input is basically the programs version of gravity, it's what tells your program where 0 is on your physics engine and reacting accordingly

Next is our output setting and physics model (aka the pendulum)

You will want your output as your item/ear flop/movement, but if you move it after adding this you'll see it's not reacting so you needed to add a pendulum point

Bellow pendulum setting pressing add, adds a point to the pendulum, and the NO (such as 1) is what number the blue dot is in the preview

To go over the basics

Duration- how long

Shaking influence- how much the point shakes when moved

Reaction time- how fast it reacts to a movement

Overall acceleration- how fast it moves after a movement

For this I set my duration to 15, since I don't want alot of shake/wiggle when the ears move I lowered the shaking influence, reaction time is 1 so it's a more simple but steady movement if you wish for the ears to move faster when you tracking or slower you can up or lower this, overall acceleration I keep at base 4.

This is the basis for the ear tracking

The left side is the same thing id just duplicate the group you just did change out the ear output for the other side parameters

If own of the angles is reacting the wrong way (such as opposite direction you want) you can in your input setting press reflect which will make it move the opposite direction output wise for that parameter movement

Thank you all so much for reading

Honestly these explanations are really fun to do and gives me a long time to yap and help people with issues I ran into myself- I kinda hope maybe this will help someone in the future who was just as stuck as me

blend settings go brrrrr

To try this on your own rigs, select the deformers or meshes you've already rigged. Ctrl+Shift+C when on the default keyform. Ctrl+Shift+B when on the keyform you want to adjust. Have fun :D
