Set-up Guide
4th step : Tune up Live2d model
Now that you know what each button does, let’s check the most important one: The model configuration
The model I sent you is more or less configured but sadly I can’t do the fine tuning for you since face shapes do a lot on tracking so I’m afraid it’s your responsibility adjusting the final details of your model.
Let’s go step by step:
Clicking on the config wheel will show a new toolbar on the up-left corner of your screen:
1. The first page you encounter is the wheel. Here you can find many general configurations regarding Vtube Studio You can check them yourself but I will highlight some of the most interesting features:
Setting GPU priority to Vtube Studio might help if your model is lagged. A new instance might be helpful if you want to run two models at the same time. This option is only available if you purchase Vtube Studio (Recommended, removes watermark)
2. The second page is the camera. These options are for webcam. However, there are some interesting options. I recommend setting VTS to work at 60FPS if possible, 1920x1080p.Â
(DO NOT TOUCH THE MASKS, SINCE DOING SO MIGHT BREAK YOUR MODEL)
You can, however, play with the lighting of the model. Make sure to click on “off” if you want the model to go back to the original lighting! (DO NOT TOUCH THE MASKS UNDER ANY CIRCUMSTANCES)
3. Model parameters configuration
Here you will find the most interesting and complicated configurations for your model.
First, let’s take a look at some simple things. In this page, you can change the model display name (clicking on it) and the avatar (same way).
You can change them at your will, just take into account that I will make a placeholder picture for you, and you can keep it if you want, it’s really not that important.
You can use the option “Fix white outlines” if you find out that your model looks a bit “teared apart” which means thin white lines between pieces.
There’s no need for this if you can’t see them and I recommend making a backup before doing so.
DO NOT TOUCH DISABLE WORKSHOP SHARING AND AUTO SETUP.
This is a bit more advanced but you can use the “Customize model” option to custom your model however you want. You can, for example, choose which pieces (artmesh) will be affected by the lighting or even change pieces base color. Please, contact your artist before doing so since not all artists are fond of having their art modified like that.
It’s as easy as clicking on the pieces and modifying the lighting force on them. As you can see in the following screenshot, I clicked on the eye icon to know what artmesh it is and set the iris artmesh (artmesh12 and artmesh16) to 0. That way, the lighting is not affecting that piece at all. Then you just have to modify the lighting to get this effect.
When you are done, you can set everything back to 1 if you want to restore the original setup, or just click on “off” on the lighting tab.
Next is "Physics Settings"
I personally make my riggings completely physics-based so turning off physics will freeze the model. I personally recommend setting physics framerate to 60fps for my rigged models.
You can also play around with physics strength as much as you want but please take into account that will easily break your model since physics doesn’t affect only the hair (though you can change that clicking on the wheel next to “physics strength”).
Please contact your rigger before doing so since we don’t really like our models to look broken. Just remember to set it back to 50 when you are done playing.
Wind strength is an interesting option if you want your hair to move by its own, though it has the same problem as physics strength since physics affect more than the hair.Â
There are some things you need to beware about:
1. You can change the name if you want but it isn't necessary.
2. Input: This is a Vtube Studio parameter. It’s based on the tracking. In this case, the input says: “When FaceAngleX is detected...”, which means: “When the tracking notices you move on the X angle... (turning left and right)”.Â
3. Output: This is a Live2D parameter. It’s based on the rigging. In this case, the output finish the previous sentence. “... then the
ParamAngleX activates”, which means “... the model will move on the X angle”.
Then, we have the following sentence: “When FaceAngleX (input) is detected then the ParamAngleX (output) activates”, which means: “When the tracking notices you move on the X angle, the model will move con the X angle”. That’s how input and output works.
4. Limit range: I don’t usually use this feature but it’s a limiter in case you don’t want values to exceed the limit. You can leave them turned off if you want.
5. Smoothing: This basically makes the parameter go “smoother” but also slower. The tracking isn’t perfect and sometimes it will stutter. Smoothing solves this problem by ignoring mini-changes on values. However, this also implies that the model won’t be as reactive as it could be.Â
6. Auto-blinking: This will make your parameter value move fast every X time. Useful for, for example, eye blinking if your tracking isn’t good enough to track your eyes or you don’t have a tracking device at all. I don’t really use it on my riggings for models that will be tracked with webcam.
7. Auto-breathing: Same as auto-blinking but the movement will be much slower in time.
8. IN values: These are the standard Vtube Studio tracking values.Â
9. OUT values: These are the standard Live2D rigging values.
For model configuration set-up guides, I will share amazing tutorial videos from YoshinoArt on Youtube, Radd on X and Anata NFT on Youtube since it is better explained with video.
Since Live2d models are not plug and play, you must calibrate them to your face, provide good lighting and camera in order to get the best result. It is also recommended to practice movements to appear more natural. Also be more expressive than usual (exaggerated) will make your model looks alive.
