[1] Decoration brushes - brush tip images

The term “Decoration brush” refers to a type of brush that has an “image” registered as its brush tip. The general procedure is to create an image for the tip of the brush, and then registering that image to the brush.

Depending on their registered image, decoration brushes in CLIP STUDIO PAINT are roughly divided into the following two categories:

A: A Decoration brush that draws with the selected drawing color.

B: A Decoration brush that draws with a fixed color image.


More specifically, they draw as follows. Using the initial decoration brushes as an example,


A: Decoration brushes using the selected drawing color.

“A” brushes are brushes such as A-1[Sunflower] OR A-2[Melody], which are effected by red, the selected drawing color. As seen in sample A-1 with the [Sunflower] brush, this type of brush can also be used with a main color and a sub color.


B: Decoration brushes with fixed color images.

“B” brushes such as B[Barbed wire] are drawn with the image’s color regardless of the drawing color.

After deciding on which decoration brush to make, let us go into details on how to create each brush tip image.


On how to save and set the created brush tip images, refer to the following lesson.

Decoration brushes can be used for various expressions depending on the drawing color. In the following explanations, we will show several materials that are suitable for each decoration expression. Please use them as reference when creating materials. After registering the brush, please try it out and check if it turned out the way you imagined it!


[2] A: How to create brush tip images that allow for freely changeable colors

We will create a decoration brush tip image that can freely change colors.


· Layer selection

First, create a layer with the expression color set to [Gray] or [Monochrome].

When creating a two-color brush, draw the part that is the main color with black and the part that should become the sub-color with white.

When creating a single-color brush, draw the part that will become the main color with black only.

↓The expression color of a layer can be set with the [Layer Property] palette.


A brush created with white and black can reflect two colors you like.

For example, with a grass material, it is possible to draw line art in black and fill in the inside with white. This way the color of the leaves and the outlines of the leaves can be changed freely, creating a very useful brush.



■Creating a decoration brush on a layer with a [Gray] expression color


As opacity can be expressed with this type of layer, it is suitable for expressing shades of one color. When using this kind of material, you can select the color of your choosing.

Materials that have mixed densities such as effect brushes (“fluffy”, “sparkly”) are best created with a gray layer.


With a brush that uses this kind of brush tip image, the following image can be drawn.

When a drawing color is set as the main color, the brush tip image’s black portions are replaced with the main color, the white portions are replaced with the sub-color, and each are rendered accordingly.


When the drawing color is set to sub-color, it is drawn with the sub-color only.


When the drawing color is set to transparent, the black part of the brush tip image will be erased and become transparent.



■Creating a decoration brush with a [Monochrome] expression colored layer


If the expression color of the layer is set to monochrome, you can create the decoration brush in black and white.

The difference compared to a [Gray] layer is that gradients and anti-aliasing can not be expressed.


With this kind of brush tip image set, drawing works as follows.

The black part becomes the main drawing color, while the white part is replaced with the sub-color.


When the drawing color is set to sub-color, only the sub-color is drawn.


When the drawing color is set to transparent, the black part of the brush tip image will be erased and become transparent.


[POINT]

Although there is no anti-aliasing for this kind of decoration brush, when using the decoration brush on a layer with more color depth such as gray or color, anti-aliasing will be applied when changing the brush size etc.


[3] B: Creating brush tip images with fixed color images

We will create a decoration brush with a brush tip image that can draw with its original colors.

The color of the image will be expressed as is, an the colors cannot be changed when using them.

These brushes are best used for materials that are realistic, use multiple colors, or need to be specific colors.


· Layer selection

First, create a layer with the expression color set to [Color].

↓The expression color of a layer can be set with the [Layer Property] palette.


As an example, we will make a red and blue colored decoration brush.


A brush with a brush tip image created on a color layer will be drawn with the colors used when it was created, regardless of its drawing color.

Apart from the color expression, it is sometimes used when wanting to draw with constant density even in gray or monochrome settings.


[POINT: When publishing via CLIP STUDIO]

The usability of materials is sometimes hard to determine unless materials are downloaded and used in the application.

Especially when publishing fee-based materials, it is important to write details on its use to avoid people having false expectations as to what to do with the acquired materials.

It is recommended to describe the expression color (monochrome, gray, color) of the decoration brush and the layer type the material should be used on in particular.


[4] Types of decoration brushes

A decoration brush is a tool used to draw patterns (images) continuously. In CLIP STUIO PAINT, brushes that take advantage of the brush tip image are defined as decoration brushes.

All settings can be changed and adjusted in the [Sub Tool Detail] palette. Since there are many elements to adjust, this part will introduce only elements that are related to decoration brushes.



■ 1. Stamps


These decoration brushes can be used like a stamp, spacing each pattern, while still drawing continuously.

This is effective when drawing patterned shapes.

Set [Brush shape] → [Stroke] → [Gap] in the [Sub Tool Detail] palette to “Fixed” and adjust the values below.



■ 2. Spray effect


This setting scatters the pattern as if drawn with an airbrush.

These brush settings are effective when wanting to draw scattered patterns like cherry blossoms and such.

Set the [Brush shape] → [Spraying effect] → [Spraying effect] in the [Sub Tool Detail] palette to “ON” and adjust the elements below.



■3. Ribbons


Ribbon brushes draw a pattern continuously, while the image is deformed and drawn according to the curvature of the line.

This is effective when drawing string-shaped patterns.

Set [Brush shape] → [Stroke] → [Ribbon] in the [Sub Tool Detail] palette to “ON”.
