Customizing Texture brushes

To quickly get started with texture painting, choose any of the brush variants available in the Texture Cover and Texture Source Blending brush categories. In addition, Corel Painter gives you full control to create custom Texture brushes.

There are a number of different methods that allow you to specify whether a Texture brush uses the color, luminance, or both the color and luminance information of a selected texture and whether it interacts with paper grain.

You can control the amount of texture that a brushstroke reveals.

You can also specify how Texture brushes interact with paint already applied to the canvas. For example, Texture brushes can either cover or blend with the underlying image to create amazing effects.

Texture brushes can use the original texture color or mix the texture color with a different color. For example, if the texture that you want to use doesn't match the tone and color of your composition, you can sample a color from your painting and mix it with the texture color. You can choose an expression such as pressure, tilt, direction to vary the amount of color you mix into the texture. For more information, see Expression settings.

You can smudge a texture. Smudging reveals a little of the current texture as you push, pull, and smear pixels. You can choose a fixed amount of smudging or vary the effect with an expression. For example, if you link smudging to stylus pressure, light pressure will reveal more texture detail, increased pressure will reveal less detail.

For even more astonishing results, you can use dab stencils to shape the dab and modify the opacity of Texture brushes. For information about dab stencils, see Dab Stencil controls.

Texture brushes can have depth and support the impasto Depth and Color and Depth drawing methods. Corel Painter uses the luminance (brightness) information in the texture to determine how much depth is applied within a stroke. Light areas of the texture receive more depth; dark areas receive less. Black areas appear flat. For more information about impasto methods, see Adjusting and creating Impasto brushes. You can add or remove depth, and control the effect by manipulating the lighting of the painted result. Add depth to Texture brushes to create pores on skin, scales on a lizard, thick brick walls, and prickly pebble board.

Experiment with different brush settings to produce the effect you like. Texture brush settings are saved as part of a brush variant or applied to any active brush. For more information, see Adjusting brushes with brush controls.

After you customize a Texture brush variant, you can associate it with a texture and save it as a brush look for use in future projects. When you save a look, it is added to the Look Libraries panel. For more information, see Saving a brush look.

To customize a Texture brush

1	In the toolbox, click the Brush tool .

4	On the General panel (Window Brush Control Panels General), choose one of the following methods from the Subcategory list box:

5	Click the Texture Brushes panel toggle button on the extended property bar (Window Extended Property Bar).

To	Do the following
Set the maximum amount of texture a brushstroke reveals	Move the Strength slider.
Blend the texture with the underlying image	Enable the Source Blending check box.
Control the color of a texture	Enable the Color Control check box. Enable one of the following options: Current Color — lets you mix the original texture color with the selected color Texture Color — lets you use the original texture color Tips: To control the amount of color you apply with a brushstroke, move the Amount slider. You can choose an expression such as pressure, tilt, direction to vary the amount of color mixed into the texture. Notes: The Color Control option is not available for brushes that use the Texture Chroma or Grainy Texture Chroma methods. The Texture Color option is available only for brushes that use the Texture Luminance and Grainy Texture Luminance methods.
Smudge a texture	Enable the Texture Smudging check box. Move the Amount slider to adjust the smudging amount. Tip: To link texture smudging to an expression such as pressure, tilt, direction, choose an option from the Expression list box.

Add depth to a Texture brush

In the Impasto panel (Window Brush Control Panels Impasto), choose one of the following drawing methods from the Draw To list box: Color and Depth Depth From the Depth Method list box, choose Texture Luminance to use the texture luminance to control the appearance of depth. Drag the Depth slider to the right to increase depth, or to the left to decrease it. Tips: To adjust the appearance of depth, click Canvas Surface Lighting, and adjust the sliders in the Appearance of Depth area. To adjust the ambient and directional lighting, click Canvas Surface Lighting, and experiment with the controls in the Ambient Lighting and Directional Lighting area, respectively. For detailed information about the impasto depth controls, see Adjusting and creating Impasto brushes.

When painting with brushes that use Source Blending, you may notice overlaps when you overlay brushstrokes. To paint without overlaps, in the Texture Brushes panel, disable the Source Blending option and set the texture Strength to 100%. In the Layers panel, add a new layer, and choose the Overlay method from the Composite Method list box. Move the Opacity slider to adjust the intensity of the brush marks. This workflow produces results that are very similar to Source Blending.
