Sketching How do I? Create a shape texture brush > To create a texture brush with shape and color attributes

Apply and remove paint using brushes

Use brushes to apply paint, erase, hide, and show paint, clone regions; customize brush properties and brush display.

Introduction to brushes

Introduces brushes.

Markers, Airbrushes, Solidbrushes, Sharpenbrushes, Blurbrushes, Smearbrushes, Clonebrushes, and Hide/Show mode are not available in SurfaceStudio. The default pencils in SurfaceStudio are colored.

The sketching and painting tools in AliasStudio are collectively referred to as brushes. When you create a sketch, you use a brush to apply paint to an image layer on a canvas plane.

Paint and erase

Choose a brush tool using Paint > [Brush type ] > [Brush name] and drag in a view.

Markers, Airbrushes, Solidbrushes, Sharpenbrushes, Blurbrushes, Smearbrushes, Clonebrushes, and Hide/Show mode are not available in SurfaceStudio. The default pencils in SurfaceStudio are colored.

To select a brush and sketch with it

  1. Choose a brush tool (Paint > [Brush type ] > [Brush name]).
  2. The Pencil, Marker, Airbrush, and Solidbrush tools let you drag the stylus to apply strokes of paint to a canvas plane.

    Pencil

    Marker

    Airbrush

    Solidbrush

    The Eraser tools lets you drag the stylus to remove paint from a canvas plane in strokes.

    Eraser

    When a brush tool is active, the cursor becomes a crosshair with the letter P (paint), E (erase), H (hide), or S (show).

    When you hold the cursor over a canvas plane, the cursor also displays a preview image of how the brush will apply paint to the sketch.



    You can turn off the brush preview and radius indicator.

  3. Drag the stylus on the canvas plane to begin sketching.
  4. To quickly switch between painting and erasing using the same brush, with a brush tool active press and release 1 to paint or 2 to erase.

    To erase paint, flip the stylus around and use the eraser function at the end of the stylus.

    To create a horizontal brush stroke in an orthographic window, drag the middle mouse button or the equivalent stylus button.

    To create a vertical brush stroke in an orthographic window, drag the right mouse button or the equivalent stylus button).

    To snap a brush to a curve, click the curve button to the right of the prompt line (or hold down Ctrl Alt).

    Brushes are most responsive when you are viewing the canvas plane at its actual size (1:1 or 100%).

    Brush strokes may appear slow when you are zoomed out of a canvas plane. This is because the stroke is actually very large relative to the canvas plane.

    Brushes may be more responsive if you do not have any other windows open (for example, the Canvas Layer Editor window or the Color Editor).

    Brushes may be more responsive if you do not have any other applications running.

    If you cannot paint, the active image layer may be hidden (the cursor becomes a shape cursor) or may contain hidden paint (you cannot paint over hidden paint) or the active layer may be a shape layer (you cannot paint on a shape layer; the cursor becomes a shape cursor).

The rest of the AliasStudio windows are hidden while the brush is down. You can go to Preferences > General Preferences Preferences > General Preferences and change the setting for Hide Windows During Brush Stroke to change the amount of time (in seconds) that it will take before the windows reappear.

    • The Current Color Swatch updates with the new color.

  2. Drag the Current Color Swatch from the Color Editor to the shelf with the middle mouse button.

Set brush and paint opacity

In the Paint Panel or Brush Options window set Min Opacity and Max Opacity, and in the Brush Options window set Color Opacity.
See also Sketch on a Cintiq

Opacity is a way of representing how "see-through" a brush's paint is. (Opacity is the opposite of transparency.) You cannot see anything underneath paint that has an opacity of 1. The lower the opacity, the more you can see through the paint. Paint that has an opacity of 0 is perfectly clear and invisible.

You can also control the opacity of layers.

See Change the opacity of an image layer

Most brushes in AliasStudio have two types of opacity: brush opacity (controlled by the Min Opacity and Max Opacity options) and paint opacity (controlled by the Color Opacity option).

The difference between brush opacity and paint opacity becomes noticeable when you paint more than once over the same spot. If the brush opacity is less than 1, the paint will build up and become more opaque. If the paint opacity is less than 1 (and the brush opacity is 1), the paint will not build up.

In addition, you can make the brush opacity change based on how hard you press the stylus on your tablet. The Min Opacity is the minimum opacity for the brush (when you press lightly with the stylus) and the Max Opacity is the maximum opacity for the brush (when you press hard with the stylus). If you do not want the opacity to vary with stylus pressure on the tablet, set the Min Opacity and the Max Opacity to the same value.

To set brush opacity

Do any of the following:

To set paint opacity

In the Brush Options window, set Color Opacity.

To make any brush erase paint, set the Brush Color to black and set the Color Opacity to 0. (To keep these settings for the brush, turn on Preserve Color.)

Set marker wetness

In the Paint Panel or Brush Options window set Wetness.

By default, most Marker brushes have a Wetness value of 0.5, which simulates ink from a somewhat used marker. You may want to increase the Wetness to simulate a brand new marker, or reduce the Wetness to simulate a dry or semi-dry marker.

When using a marker, pressing the stylus against the tablet without moving it will continue to apply paint to the canvas plane just like a real marker on paper.

If the Wetness is high (for example, 0.9), paint will be applied to the canvas plane more rapidly than if the Wetness is low (for example, 0.1). You can therefore create different types of strokes with a marker simply by moving the stylus faster or slower.

To set marker wetness

In the Paint Panel or Brush Options window, adjust the Wetness slider or enter a value in the Wetness field.

Set blur strength

In the Paint Panel or Brush Options window set Blur Strength.

By default, the Blur brushes have a Blur Strength value of 3.0. You may want to increase the Blur Strength to make the image or strokes less defined, or reduce the Blur Strength to add just a touch of blur (perhaps to get rid of some JPEG artifacts in an imported image).

To set Blur Strength

In the Paint Panel or Brush Options window, adjust the Blur Strength slider or enter a value in the Blur Strength field.

See also Blur paint.

Set sharpness and sharpen strength

In the Paint Panel or Brush Options window increase the contrast between strokes by adjusting Sharpness and Sharpen Strength.
> Sharpness

Controls the amount of sharpening. The valid range is 0 (no sharpening) to 10 (maximum sharpening).

> Sharpen Strength

By default, the Sharpen brushes have a Sharpen Strength value of 1.5. You may want to increase the Sharpen Strength to make the image or strokes harder or more defined, or reduce the Sharpen Strength to add importance to some edges without calling too much attention to them.

To set Sharpness and Sharpen Strength

In the Paint Panel or Brush Options window, adjust either the Sharpness or Sharpen Strength slider or enter a value in the Sharpness or Sharpen Strength field.

See also Sharpen paint.

Set brush size, shape, and profile

In the Paint Panel or Brush Options window set Min Radius, Max Radius, Aspect, Rotation, and Brush Profile.
See also Sketch on a Cintiq

Brushes apply paint to a canvas plane in strokes. A stroke consists of a series of closely spaced stamps. (If you click a brush onto a canvas plane, instead of dragging the stylus, you will apply a single stamp of paint.) The default brushes (Pencil, Marker, Airbrush, and Solidbrush) have circular stamps. You can, however, control the size and shape of brush stamps to produce different types of strokes.

> Size

The size of a brush is based on its Min Radius (when you press lightly with the stylus) and its Max Radius (when you press hard with the stylus). If you do not want the size to vary with stylus pressure on the tablet, set the Min Radius and the Max Radius to the same value.

Small brushes are more responsive than large brushes.

> Shape

The shape of a brush is based on its aspect ratio. An aspect ratio of 1 means the brush stamp is circular. The lower the aspect ratio, the flatter the brush stamp. The angle of a flat stamp is based on the brush Rotation.

> Profile

The profile of a brush controls the softness of the brush stamp edges.

To set the size of a brush

Do any of the following:

To set the shape of a brush

Do any of the following:

To set the profile of a brush

In the Paint Panel, or on the Stamp tab in the Brush Options window, set Brush Profile to Hard Solid, Solid, Buzz, Regular, or Custom. If you select Custom, an editable graph of the brush profile opens.

The Point Menu enables you to add, delete, or move points on the graph.

A slower slope represents a fuzzier edge; a steeper slope represents a sharper edge. The height of the graph represents opacity on a scale of 0 - 1.

Set brush stroke properties

In the Brush Options window set Spacing Bias, Spacing Noise, Rotate to Stroke, and Rotation Jitter in the Stroke section of the window.

Brushes apply paint to a canvas plane in strokes. A stroke consists of a series of closely spaced stamps. (If you click a brush onto a canvas plane, instead of dragging the stylus, you will apply a single stamp of paint.) You can control how strokes are generated from stamps.

For example, you can control the spacing between stamps in a stroke so they are close or far apart, or so their spacing has an element of randomness.

You can make stamps rotate in the direction of a stroke or always remain in the same direction, or rotate with an element of randomness.

To set brush stamp spacing

In the Brush Options window, do the following:

To set brush stamp rotation

In the Brush Options window, do the following in the Brush Stroke section:

Snap a brush to a curve

Hold down Ctrl Alt, click the curve and drag along the curve.

When you are sketching, you can snap a brush to a curve (or surface isoparametric curve or curve-on-surface). This allows you to use curves as sketching guidelines.

To snap a brush to a curve

  1. With a brush active click the curve snap button to the right of the prompt line, or hold down Ctrl Alt, to activate curve snapping.
  2. Move the stylus so the brush profile is near the curve.
  3. The brush profile will jump onto the curve.

    To set the brush curve snap tolerance, choose Preferences > General Preferences Preferences > General Preferences r, then choose Paint from the left side of the option window, and set Brush Curve Snap Tolerance to the number of pixels the brush cursor must be from a curve in order for the brush profile to jump onto the curve.

  4. Drag the stylus along the curve.
  5. Click the curve snap button again, or release Ctrl Alt, to de-activate curve snapping.
  6. You can snap to invisible curves (see ObjectDisplay > Invisible ObjectDisplay > Invisible) or curves on invisible layers (Layers > Visibility > Invisible Layers > Visibility > Invisible).

Sketch using brush symmetry

Choose Paint > PaintSymmetry > Modify canvas brush symmetry Paint > PaintSymmetry > Modify canvas brush symmetry, select a brush, and start sketching.

You can sketch and automatically have the strokes mirrored, either bilaterally or radially.

To use bilateral symmetry

  1. In the option box, set Symmetry Type to Bilateral
  2. The axis of symmetry appears as a dotted line.

  3. Modify the axis in the following ways:
    • Drag the central red dot to move the axis.
    • Drag a red double-arrow to change the orientation of the axis. The axis rotates around the other double-arrow.
    • Move the double-arrows along the axis to change the rotation pivots.
    • Click the Reset button at the bottom of the window to reset the axis to its original position.
  4. Select any brush and start sketching.
  5. Everything you sketch on one side of the axis automatically gets drawn on the other side, as a mirror image.

To use radial symmetry

  1. In the option box, set Symmetry type to Radial, and Num Radial Sections to the number of sections.
  2. A number of axes of symmetry (equal to the value of Num Radial Sections) appear as dotted lines radially emanating from a center point.

  3. Modify the axes in the following ways:
    • Drag the central red dot to move the center point.
    • Drag the red double-arrow to change the orientation of the axes (by rotating them around the center point).
    • Click the Reset button at the bottom of the window to reset the axes to their original position.
  4. Select any brush and start sketching.
  5. Everything you sketch within one of the sections automatically gets drawn in all the other sections, creating a sort of kaleidoscopic effect.

To stop sketching symmetrically

Do one of the following to toggle off symmetry:

Sketch using predictive strokes

When sketching, the predictive strokes feature perceives what you're trying to draw, and redraws it with more precision. You can use predictive strokes to create straight lines, curves, and ellipses.

To use predictive strokes

  1. Choose Preferences > Interface > Hotkeys/Menus Preferences > Interface > Hotkeys/Menus, and open the Special > Paint section.
  2. Assign a hotkey to Toggle predictive stroke (curvature) to draw curves, circles, or ellipses, or to Toggle predictive stroke (line) to draw straight lines.
  3. Click Apply.
  4. Choose a brush, then press the hotkey.
  5. The cursor changes shape to indicate the predictive stroke mode you're in.

    Your paint stroke is redrawn when the stylus is lifted from the tablet, or the mouse button is released. The stroke will either be a circle, ellipse, or arc if Toggle predictive stroke (curvature) is on, or a line if Toggle predictive stroke (line) is on.

  6. To turn off predictive stroke mode, press the hotkey again.

Clone an area

Choose Paint > Effectbrush > Clone brush Paint > Effectbrush > Clone brush, click to select a source texture, then click or drag to apply the source texture.

This feature is not available in SurfaceStudio.

To clone an area

  1. Click the region of the image you want to use as a source texture.
  2. Click or drag anywhere on the image to apply the source texture.
  3. As you drag, more of the source texture is applied.

    To select a new source texture, hold down the L key and click the source texture.

    To resize the Clonebrush, hold down the R key and drag:

    • up to increase the minimum radius
    • down to decrease the minimum radius
    • right to increase the maximum radius
    • left to decrease the maximum radius.
    • To adjust the Clonebrush opacity, hold down the O key and drag:

    • up to increase the minimum opacity
    • down to decrease the minimum opacity
    • right to increase the maximum opacity
    • left to decrease the maximum opacity.

Flood an area with paint

Choose Paint > FloodFill Paint > FloodFill and click the area or color you want to fill.

This feature is not available in SurfaceStudio.

To flood or fill a consistently colored area of an image layer with paint

    The cursor becomes a paint bucket.

  1. Click the area or color on the image layer you want to fill with paint.
  2. In the Flood Fill Options section of the Paint Panel do the following:
    • To set the fill paint color, see Set brush paint color.
    • To set the fill paint opacity, set Opacity. (For more information on opacity, see Set brush and paint opacity.)
    • To set the range of colors to be filled, set Tolerance. A low value fills pixels having a color very similar to the color you clicked. A high value fills pixels having a broader range of colors.
  3. Click Accept.
  4. After Accept has been clicked, flood fill options are no longer editable until another floodfill operation is initiated. You can edit and modify the flood fill options up until you click Accept, mouse down on the image for another flood fill operation, or exit the tool.

    Alternately, you can set the Flood Fill Options before clicking the area or color on the image layer you want to fill.

Hide and show paint

In the Paint Panel or Brush Options window set Brush Mode to Hide or Show.

This feature is not available in SurfaceStudio.

See also Sketch on a Cintiq

You can use any brush to hide paint in an image layer. Hidden paint is not visible, but it still exists. You can later show hidden paint using any brush.

You can also easily show all hidden paint in an image layer or erase all hidden paint in an image layer.

You can sketch on an area of an image layer that contains hidden paint, but you won't see what has been painted until you choose Edit > Clear hide show in the Canvas layer editor.

To hide or show paint

  1. In any Paint Panel or Brush Options window, set Brush Mode to Hide or Show.
  2. Drag the stylus on the image layer to hide or show paint.
  3. To quickly switch between hiding and showing paint using the same brush, use the hot key editor to assign shortcuts.

To view hidden paint

  1. In any Paint Panel or Brush Options window, set Brush Mode to Show.
  2. Move the cursor over the hidden paint, but do not press the stylus against the tablet or press the mouse button.
  3. The brush preview will momentarily reveal the hidden paint beneath it.

To show all hidden paint in an image layer

  1. Select the image layer you want to show hidden paint on.
  2. in the Paint Layer editor choose Edit > Clear hide show.

To erase all hidden paint in an image layer

  1. Select an image layer you want to delete hidden paint from.
  2. In the Plane/Layer Editor window choose Edit > Clear hide show.

Create a texture brush

Create a brush that paints a captured brush stamp

To create a texture brush

  1. Select the brush style you want to start from -- for example, Solid brush, Airbrush, Pencil, etc.
  2. In this example we will create a simple leather texture brush, using a Solid Brush profile.

  3. First we scan our leather sample and save it in a standard image format like tiff.


  4. Open the Brush Options window and select the Stamp tab. Select the Shape and Texture option from the Capture Mode pop-up menu.
  5. You can also use the Brush Stamp Options in the Paint Panel.

  6. The brush cursor changes and the prompt line requests you to select the texture region. Note you can change the radius using the standard modifier key R if required. The moment you place a single click on the canvas, the texture is grabbed from the current image layer and loaded into the brush stamp. Note how the tool's icon, brush stamp and brush stroke preview have been refreshed in the Brush Options window.
  7. Create a few sample strokes on the image layer to test the brush effect. You may need to modify the distance between each stroke by adjusting the Brush Stroke > Spacing Bias and the Brush Profile, depending upon your texture style and personal preference.


Create a shape texture brush

Create a wheel texture brush with transparent holes by using a Solid Brush profile.

To create a texture brush with shape and color attributes



    The first step we need to do is remove the pale gray background using the MagicWand or shape mask tools.

    In this example, we will use the MagicWand tool because it's a quick way to select pixels for removal.

  1. Select your photograph or image and resize to approximately the brush size you require.
  2. Click on the outside of the image and adjust the tolerance in the Paint Panel.


  3. Hold down the "A" key while you select all the other gray areas you want to remove. Using the "A" modifier key allows you to add to the magic wand selection.


  4. The alloy wheel and tire are now protected by the selection mask.

  5. Select Windows > Editors > Canvas Layer editor Windows > Editors > Canvas Layer editor and click the erase image layer button to delete the gray pixels.


  6. Now select Pick > Nothing Pick > Nothing from the tool palette to delete the selection mask.


  7. Select the brush style you want to start from. You can select this from either the tool palette or the paint control panel -- Solid brush, Airbrush, Pencil, and so on.
  8. Open the Brush Options window and select the Stamp tab. Select the Shape and Texture option from the Capture Mode pop-up menu.
  9. The brush cursor changes to a camera within the radius circle, and the prompt line request you to select the texture region. Note you can change the radius using the standard modifier key R. The moment you click on the canvas, the texture is grabbed from the current image layer and loaded into the brush stamp. Note how the brush stamp and brush stroke preview refresh in the brush editor to show the stamp selection.
  10. Try a few sample strokes on the image layer to test the brush effect. You may need to modify the distance between each stroke by adjusting the Brush Stroke > Spacing Bias and the Brush Profile, depending upon the texture style and personal preference.

You have now created a texture brush that will create wheel stamps with transparent spoke holes.
