Bristle 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:
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:
-
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:
-
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:
-
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.
Average Smudge Color - This setting controls how color smudging is applied by the brush. At low values, each bristle smudges the colors it touches individually, creating more textured, varied strokes. At high values, the brush uses a single, averaged color.
Use Automatic Value - When enabled, Average Smudge Color is automatically set based on the currently used Oiliness value (Oils and Express Oils only).
Use Blend instead of Average Smudge - When enabled, high Average Smudge Color values will blend colors instead of smudging.
Color¶
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.
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.
Color Noise per Bristle - Set variations in color per each bristle within the brush using the HSLuv palette.
Color Noise per Stroke - Set variations in color per each new stroke using the HSLuv palette.
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 Texture
Add extra texture to your brush with one customizable background texture which is 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 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.
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.
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.
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.
