Object Edition

Mesh / ArtMesh

A set of triangles composed of vertices and lines is called a “mesh”.
PSD images loaded into Modeler are always placed on the canvas with this “mesh” assigned.
The image with the mesh assigned is the “ArtMesh”.

About ArtMesh


polygon apex edge

The triangles of a mesh, which is a set of triangles composed of vertices and lines, are called “polygons”.
The white points of a mesh are called “vertices”.
The lines of a mesh are called “edges”.


Deformer (warp deformer, rotational deformer)

A deformer is a container in which the vertices of an ArtMesh can be deformed and moved together.
There are two types of deformers: “Warp Deformers”, which can create curved shapes, and “Rotation Deformers”, which can rotate and scale.
Each can do different things, so they are used for different purposes.

About Deformer



Each element placed on the canvas, such as an ArtMesh or deformer, is called an “object”.


Parameter section


Parameters” can be used to store the transformation, position, etc. of an object.

About Parameters


key-key form

The point on the parameter where the shape is stored is called the “key”.
The shape specified by a key is called a “key form”.

Edit Parameters




Groups of characters divided by their components (eyes, nose, etc.) are called “Part”.
“Parts” are displayed in the Parts palette section.

About Parts


Draw order

The value that specifies the order in which the ArtMesh overlap is called the “Draw Order”.
It can be set between 0-1000, the larger the value, the earlier it will be displayed.

About drawing order


Texture Atlas

The image of the ArtMesh is called a “texture atlas”.
Typically, the format is PNG and the image size is created as n squares of 2.

This is required when exporting models for inclusion in the SDK or for Cubism 2.1.
(Not required for video applications.)
