Cubism Modeler


Welcome to the User Manual for Cubism Modeler.
The navigation menu to the left contains all the information you need to get your project started.


    What is Cubism Modeler

It is a tool to create moving characters from flat images, called Live2D.

The model is created using layered images (PSD format and PNG format) with parts of the character separated into layers. For example, the bangs, eyes, lips, and clothes, each is designed to go onto their own layer.
Modeler will then create polygons to control the deforming and transforming of parts, which will create movement and enable facial expressions.
Some of the most useful features of Modeler is the creation, editing, and controlling the hierarchy of deformers that affect these polygons.


    Model Production Process

There are two phases of the modeling process inside Modeler.
The
"Texture Editing" phase, and the "key form Editing" phase.

Once you receive the artwork from the artist, you begin the Texture Editing phase which adds polygons to each part. Next you proceed to the Key Form Editing phase which controls how these parts interact with each other.

Texture Editing
Here polygons are assigned to the parts that have their own layers, and are laid out flat on the canvas to allow the program to read each part separately.
It will look something like this



Key Form Editing
Here, the interactive character comes to life by morphing and changing the parts, the eyes can smile, the mouth can change shape into a smile or a frown, and the head can rotate to look in different directions!
The character can mimic the speech patterns of Anime characters when given the correct mouth shapes.

In Live2D, each distinctive shape of a model part is called "Key Form", in the image above, the character shows 7 Key Forms. 

Creating a limited number of Key Forms and combining the effect will give you more shapes. For example, the [mouth shape] that controls the smile and frown etc, and [open/close state] of the mouth can be recorded into two separate parameters (Key Form controllers) to achieve this.
Modeler automatically generates the transition between each Key Form, all you have to do is change the parameter from one value to the other!


Elements on the Canvas: what is 'Object'?
The separated layers of the character's image are named "Drawing Object" once they are on the editing canvas.
Since they have polygons, you can edit each polygon separately to alter the shape of a Drawing Object, and save those different shapes as Key Forms.

However, Modeler also allows you to create an envelope that controls all the Drawing Objects together to move as one, such as controlling all the parts of the head together, or moving all parts of the hair to one direction when the wind blows.
This tool is called "Deformers".
Deformers appear on the canvas as square or rotating controllers, and can have Key Forms and be moved just like Drawing Objects.

Together, the [Drawing Object] and the [Deformers] that control them, are called "Object".


    Once the Model is Complete

Having a complete Live2D Model is only the beginning!
The next step would be making wonderful animations using Cubism Animator, to create movie clips, gif images, and interactive games and apps.

The model data saved by Modeler is [CMOX], and can be read by both Modeler and Animator.

Other formats that you can edit are [MOC] files, they are designed to save the Key Forms, Texture location, and other information to use with apps and games.
