This page is for Cubism version 4.2 or earlier. Click here for the latest version.

Brush Selection and Settings

Default brush settings

When creating a new ArtPath in the Editor, the default settings will be the following [Default Brush Settings].
If line width and brush settings are predetermined, it is convenient to create an ArtPath after selecting a brush in [Default Brush Settings].

[Line Width], [Opacity], [Line Color], and [Brush] can be set. [Line Color] and [Brush] are explained in detail in the next section.

Note: Please note that you cannot set up your own brushes from the [Default Brush Settings] in the [Tool Details] palette. The settings for your own brushes are set in the [Inspector] palette.

Brush line color

You can adjust both the Line Color and the Opacity of the line color.
If the Brush material itself has a color, the color of the material can be displayed by reducing the Opacity.

Note: Line color is like painting over the brush material with the line color you have set.

Click on the color box of the [Line Color] item in the [Tool Details] palette and [Inspector] palette.

The following dialog box will open.

Line Color can be specified directly from the color circle, entered as a color code, or selected with an eyedropper.
You can adjust the brightness by dragging the bar (1) up or down.

The opacity of the line color can also be adjusted by dragging the bar (2) up or down.

Brush selection

You can select a brush from the [Tool Details] palette. The brushes that can be selected here are those registered for the model.

To change the ArtPath Brush Settings after it has been created,
select the ArtPath you want to change and select a brush from the [Inspector] palette.

Brush settings

New brushes can be created and textures can be adjusted.
While adjusting the settings, the adjustment result is reflected in real-time on all ArtPaths for which the brush is set.

Note: The brush content set here will be saved in the cmo3 file being edited. It is not saved in the Editor.
 You can export brush settings by using “Export/Import Brushes.”.

Clicking on the red framed gear icon in the [Inspector] palette shown in the following image opens the [ArtPath Brush Settings] dialog box.

Sprite method

Setting/NameDetailsBehavior when changing values
NameAny name can be set.
IDAny ID can be set.
Texture / ImportLoad your own prepared brush image.
Drawing methodWhen multiple pieces of material are loaded, they will be in sprite format.
See “Creating and Adding Your Own Brushes” for more information.
Line Width MagnificationThe magnification factor for the line width of the brush texture can be set numerically in the range of 0-100.
DensityBrush texture density can be set numerically in the range of 0-10.
The higher the density, the more it affects the Editor’s overall performance.
 
QualityTexture quality can be set numerically in the range of 0-100.
The higher the quality, the higher the resolution of the texture selected for smaller line widths.
The lower the quality, the lower the resolution of the texture selected for larger line widths.
 

For details on the mechanism of the sprite method of brush drawing set up here, see “Sprite Method Drawing Mechanism.”

Mesh method

Note: The default setting of “Watercolor” does not have a border setting, so a border setting has been added for the purpose of this explanation.

Setting/Name Details Behavior when changing values
Name Any name can be set.
ID Any ID can be set.
Texture / Import Load your own prepared brush image.
Drawing method

When a single material is loaded, it will be in mesh format.
See “Creating and Adding Your Own Brushes” for more information.

Line Width Magnification

The magnification factor for the line width of the brush texture can be set numerically in the range of 0-100.

Top border

The area above the top border of the brush texture can be set numerically in the range of 0-1.

Note: 0 is the top edge of the screen, 1 is the bottom edge of the screen.

Bottom border

The area under the bottom border of the brush texture can be set numerically in the range of 0-1.

Note: 0 is the top edge of the screen, 1 is the bottom edge of the screen.

(Width on Canvas)
Top border 

The display ratio of the set “Top border” area to the actual above-top-border area on the canvas can be set numerically in the range of 0-100.

Note: The appropriate value depends on the resolution of the canvas.
It is recommend to make adjustments while looking at the actual ArtPath drawn on the canvas.
(The figure on the right is an example of the display on the canvas.)

Note: The border width set here is always maintained even if the line width of the ArtPath is changed.

(Width on Canvas)
Bottom border

The display ratio of the set “Bottom border” area to the actual under-bottom-border area on the canvas can be set numerically in the range of 0-100.

Note: The appropriate value depends on the resolution of the canvas.
It is recommend to make adjustments while looking at the actual ArtPath drawn on the canvas.

Create and Add Your Own Brushes

You can also prepare PNG images of your own brushes and load them into Editor for use.
The original image for the brush can be created using image creation software such as Photoshop or CLIP STUDIO PAINT.

There are two types of brush images that can be loaded into Editor.

Sprite methodMesh method

Create images using the sprite method

Please prepare at least two images for each brush size. Increasing the size provides resilience against image resolution degradation.
When creating an image, make sure that the brush size becomes reduced in proportion to the image size.
(E.g. 400 x 400, 300 x 300, 200 x 200)

The created image should be exported as a transparent PNG.

Note: There is no clear rule for brush size, but we recommend that you prepare a larger (thicker) size than you want to use in the source image.
Note: There is no color specification at the time of creation. The color will be drawn in the color specified at the time of creation if the opacity of the ArtPath line color setting in the Editor is set to 0.
 It is also possible to change the line color setting to any desired color.

Create images using the mesh method

There is one image to be prepared.
The created image should be exported as a transparent PNG.

Note: There is no clear rule for size, but we recommend that you prepare a larger (thicker) size than you want to use in the source image.
Note: There is no color specification at the time of creation. The color will be drawn in the color specified at the time of creation if the opacity of the ArtPath line color setting in the Editor is set to 0.
 It is also possible to change the line color setting to any desired color.
