Texture Brushes: Paint

Mixing

Paint Mode Curve Editor: Paint & Mix - This mode paints with certain pressure. If you use less pressure, from a certain point you start to mix the colors together. Adjust the pressure curve for the Paint & Mix mode of the brush using the curve editor:

Pressure curve for Paint.

Pressure curve for Mix.

Below are three examples of different settings of the Pressure curve for the Mix mode:

1. High Mixing - The curve below shows the example of high mixing - it takes longer for the first color (red) to get mixed with the new color (green). The first color prevails on the brush for a longer period of time with these curve settings:

2. Low Mixing - The curve below shows the example of low mixing - it takes a very short period of time for the first color (red) to get mixed with the new color (green). The first color mixes with the new color almost immediately with these curve settings:

3. Medium Mixing - The curve below shows the example of a setting between high and low mixing:

Paint Pressure Threshold - Represents the % at which using less pressure activates the Mix mode of Paint & Mix.

The value on the slider defines by how many percent you need to lower your pen pressure in order to start mixing. The default value is 10. This means that if you never ease your pen pressure during a stroke you will not mix anything, lowering it by 10% of the maximum pressure reached during the current stroke is required. After that, the Mix curve will control the paint mixing.

Paint Mode Curve Editor: Paint & Blend - This mode paints with certain pressure. If you use less pressure, from a certain point you start to blend the colors together. Adjust the pressure curve for the Paint & Blend mode of the brush using the curve editor:

Paint Mode Curve Editor: Blend - Adjust the pressure curve for the Blend mode of the brush using the curve editor:

Below are three examples of different settings of the Pressure curve for the Blend mode:

1. High Blending - The curve below shows the example of high blending - it takes longer for the first color (red) to blend with the new color (green). The first color prevails on the brush for a longer period of time with these curve settings:

   

2. Low Blending - The curve below shows the example of low blending - it takes a very short period of time for the first color (red) to blend with the new color (green). The first color blends with the new color almost immediately with these curve settings:

   

3. Medium Blending - The curve below shows the example of a setting between high and low blending:

   

Note

You can set the default pressure curves settings for Paint, Mix and Blend by going to Preferences > Tools. This setting will apply to all brushes globally.

Rendering

Normal - Every brushmark of the stroke builds up the layers of pigment on the canvas until the full opacity is reached.

Glaze - Turn the glazing on to build up the transparent layers of pigment on the canvas, limited by the Opacity slider in the Properties panel. Glazed strokes are used on top of one another to build up depth and modify colors in a painting:

Note

For the "Oils and Acrylics" tool only Normal mode is available.

Paint Blending determines the color blend mode used to lay down the paint on the layer. Usually, brushes use 'Default' mode (which for most of the tools is a 'Normal' mode), but you can use e.g. Linear Dodge to lighten the painting or Saturation to saturate/desaturate the painting with the brush

Original image on the left and image with Paint blending using Dodge mode on the right.

Note

These blend modes are not available for the "Oils and Acrylic" tool.

Default Color - Enable this option to save a color for the selected brush preset. Click on the color swatch to open the system color palette where you can set up the precise color of the brush.

Oils & Acrylics Impasto

Max. Impasto Height - Set the maximum loading of color on the oil and acrylic brushes (0-200).

Max. Impasto Smudge - Set the maximum smudge for the oil and acrylic brushes (0-200) and influences their impasto effect:

Thick Impasto - Achieve a more pronounced impasto with your brushes. The option is by default enabled for Rebelle 7 brush presets.

Textures

Paper Texture Strength - Set how much the paper texture should influence the brush stroke (0-100).

Texture Strength Curve Editor - Adjust the pressure curve for the Texture Strength influence using the curve editor:

Paper Texture Contrast - Set how the texture contrast should be visible on the brush grain based on the pressure of the pen (0-100):

Paper Texture Scratch - Open the settings to influence how the brush strokes should scratch over the paper texture:

• Auto - The default setting for each paper texture is used.

• Light Texture - The brush strokes scratch over the light parts of the paper texture.

• Dark Texture - The brush strokes scratch over the dark parts of the paper texture.

Legacy Paper Mode - Compatibility mode for Rebelle 6 brushes. It disables Height maps by default. It also uses Paper Texture Scratch mode from Rebelle 6 = all brushes set to 'Auto' use the dark parts of the paper, except for CA01 and CA06 papers which will use the light parts of the paper texture. Legacy Paper mode will automatically activate for Rebelle 6 brushes imported to Rebelle 7.

Background Textures

Add extra texture to your brush with two customizable background textures which are useful for example for additive texturing or the creation of random voids within your brushstrokes. This feature proves practical for generating dust effects with dry tools or achieving various scumbling and dry brush effects.

Click on the Background Texture 1 or Background Texture 2 button to reveal the panel for customization. To apply the background texture for the selected brush preset, activate the 'Enabled' checkbox and click on the icon to open the Image Library with the list of grains you can use for the background texture. You can easily import custom textures using the Import Texture button .

Texture Properties - Scale or change the brightness and contrast of the background texture grain.

Rotate - Rotate the background texture grain clockwise.

Flip Horizontally - Flip the background texture grain horizontally.

Invert - Invert the background texture grain.

A brushstroke without the background texture (top) vs. brushstrokes with a background texture used with different blend modes.

Blend mode - Set the blend mode to be used for the background texture.

Depth - Set the depth of the background texture (0-100). This value determines how deeply the background texture penetrates the brushstroke. Adjust the setting with the slider or set up a curve in Curve Editor to influence this value with different pressures applied by the pressure-sensitive stylus.

Opacity - Set the opacity of the background texture (1-100). This value determines the opacity with which the background texture will be displayed in the brushstroke. Adjust the setting with the slider or set up a curve in Curve Editor to influence this value with different pressures applied by the pressure-sensitive stylus.

Random Start - Randomize the position of the background texture grain at the beginning of the stroke.

Random Offset - Randomize the position of the background texture grain relative to the brush stamp for each stamp, so that each brush stamp is different from the previous one.

Use Shape Texture - Enable this option to influence the strength of the background texture with the shape of the primary brush.

Paper Texture Strength - Set how much the paper texture should influence the background texture. Adjust the setting with the slider or set a curve to influence this value with different pressures applied by the pressure-sensitive stylus.

Invert Paper Texture - Invert the influence of the paper texture on the background texture. By default, when Paper Texture Strength is used, the background texture applies to the valleys of the paper height map. By inverting, the background texture applies to the peaks of the paper height map.

Dual Brush

Add a secondary brush that influences the primary brush. Create an extra brush with its shape, spacing, and other parameters that follows the main brush and can add or remove parts from it, according to the blend mode.

To apply the dual brush for the selected brush preset, activate the 'Enabled' checkbox and click on the icon to open the Image Library with the list of shapes you can use for the dual brush. You can easily import custom shapes using the Import Texture button.

Texture Properties - Scale or change the brightness and contrast of the background texture grain.

Rotate - Rotate the shape of the dual brush clockwise.

Flip Horizontally - Flip the shape of the dual brush horizontally.

Invert - Invert the shape of the dual brush.

A brushstroke made with a primary brush (top) vs. brushstrokes where dual brush is enabled with different blend modes.

There are two options for how Dual Brush can be used:

• Use for Stroke - Dual Brush will influence the whole stroke. This option is disabled for Oils & Acrylics.

• Use for Stamp - Dual Brush will influence each stamp of the primary brush separately.

Blend mode - Choose the blend mode to be used for the dual brush.

Depth - Set the depth of the dual brush (0-100). This value determines how deeply the dual brush penetrates the brushstroke.

Count - Specify the number of stamps the dual brush makes.

Size - Set the size of the dual brush stamp (1-400).

Size Jitter - Specify how the size of dual brush stamps varies in a stroke (0-100).

Opacity - Set the opacity of the dual brush (1-100). Overlapping parts of the brush stamps will build up additional opacity.

Opacity Jitter - Specify how the opacity of dual brush varies in a brushstroke (0-100).

Spacing - Control the distance between the brush stamps of the dual brush (1-1000). Each brush stamp is spaced apart along the stroke by a set value. This option is available in the 'Use for Stroke' setting of the dual brush.

Spacing Jitter - Randomize spacing between the dual brush stamps (0-200).

Scatter - Brush scattering randomizes the placement of the dual brush stamps in a stroke up or down relative to the baseline of the stroke (0-200).

Distribution Curve - Open the distribution curve to set up the probability with which various scatter widths appear in the dual brush stroke.

Min. Scatter - Specifies the minimum scatter of the dual brush (0-100).

Angle Jitter - Each dual brush stamp in the stroke is rotated randomly according to the actual angle (0-100).

Follow Trajectory - The dual brush follows the stroke's trajectory rotation.

Cursor

Cursor Mode - Define the appearance of the cursor for the selected brush preset. You can choose from four different cursor modes:

• Circle - Sets up a circle cursor;
• Rectangle - Sets up a rectangle cursor;
• Shape - Sets up a cursor in the shape of the brush preset;
• Auto - Sets up the best suitable cursor based on the shape or shapes in the brush preset.

Threshold - Determines which parts of the shape's texture are taken into account for creating the cursor's shape based on opacity (1-10). Low threshold values mean that even parts with low opacity are going to shape the cursor. A high threshold determines only parts with higher opacity are taken into the shape of the cursor.
