A parameter allows you to keyframe an art mesh or deformer to specific movements or positions.
You’ll use parameters to define how something moves or changes — for example, head turning, eyes blinking, or breathing.
The parameter works by smoothly transitioning your mesh or deformer between keyed positions, like the GIF above, the logo is moving on a parameter from -30, 0, and 30.
Each parameter also has:
Angle X)🧠 You can find a list of default parameters and their IDs on the Live2D official site. These descriptions and remarks will help you choose the right ones as you rig.

To make a new parameter:
You’ll be able to:
Ranges control the amount of motion and how smoothly it plays out.
General guidelines:
⚠️ A large movement on a small range like -1 to 1 can appear jittery, especially when physics are applied.
To make a parameter affect a mesh or deformer, you need to add key points.
Then choose one of the following methods:
At the top left of the Parameter window, you’ll see three buttons:
Right-click the slider area of a parameter, and a menu will appear.
You can choose to add or remove key points from there.
A pop-up window for that parameter will open, and you can adjust the key settings just like the buttons above.
Once key points are active, you’ll see green dots appear in the parameter timeline.
You can assign more than one parameter to the same deformer or art mesh — this allows you to build more complex motion.
For example:
Angle X: -30, 0, 30Angle Y: -30, 0, 30You can link parameters by clicking the chain link icon next to each parameter in the list — this helps visualize how the positions overlap.
This is useful for when we want to rig things like the head's corner angles.
If the model was looking up and left, this would be one of the combined Angle X and Angle Y Parameter points.
Avoid using more than 2 or 3 parameters per mesh.
This is because having three parameters would create 27 different parameter positions. 9 for Angle X and Y, and then multiply that by 3 for each Angle Z position.
3x9 = 27 different positions.
Now you can see if there was was 4 or 5 parameters on one art piece or deformer, things could get pretty complicated.
A blend shape is a special kind of parameter that works just like regular parameters… but with one key difference:
👉 When you use multiple blend shapes, Live2D will automatically generate the in-between frames.
You don’t need to manually rig all 9 or 27 positions!
Since Live2D auto-generates the corner positions, you can’t control how those movements look.
For something like head angle corners, we want to control how the art meshes or deformers look, so blend shapes wouldn't be ideal.
You can create a blend shape by:
⚠️ You can’t convert a parameter into a blend shape if it already has keyframes — you’ll need to remove the keys first.
