Brush Properties
For each brush, Mari specifies several properties that you can view and change.
To view the properties of a brush, select a painting tool such as Paint, Blur, Vector Paint, Paint Through, Gradient, and Clone Stamp, then select a brush in the Shelf palette, and open the Tool Properties palette. The following properties display.
Property |
Explanation |
Example |
---|---|---|
Brush Settings |
||
Noise |
How much noise to add to each splat, to soften the appearance and reduce banding. Lower values give a harder brush, higher values a softer brush. (You can also add noise to the brush tip itself - under the Noise section below.) Range: 0.00 to 100.00, Reset: 0 |
|
Spacing |
The space between splats, as a proportion of the width of a splat. 1.00 = side-by-side (so if the tip is a circle, it would look like a string of beads.) .02 = .02 x the width of a splat. Range: 0.02 to 5.00, Reset: 0.02 |
A stroke from the same brush with spacing set to .02, .25, .50, and 1.0:
|
Paint |
||
Opacity |
How dark a stroke can be (maximum alpha). Range: 0.01 to 1.00, Reset: 1.00 |
A stroke from the same brush with opacity set to 1.00 and 0.50 with no jitter, and 1.00 with maximum jitter:
|
Flow |
Mimics how quickly paint is applied, by setting the maximum opacity in a splat. Range: 0.01 to 1.00, Reset: 1.00 |
A completely hard brush tip, full opacity, with spacing of 0.15 and flow at 1.00 and 0.30:
|
Jitter Opacity |
Whether to randomly vary the opacity (to the degree specified in Jitter Opacity Max). |
|
Jitter Opacity Max |
How much to randomly vary the opacity (if JitterOpacity is enabled). Range: 0.00 to 1.00, Reset: 0.00 |
|
Position |
||
Jitter Position |
Whether to randomly vary displacement from the line of the brush stroke (to the degree specified in Jitter Position Max). |
|
Jitter Position Max |
How many pixels at most to randomly vary displacement from the line of the brush stroke (if JitterPosition is enabled). Range: 0 to 1000, Reset: 20 |
|
Pressure Whether pressure on the graphics tablet affects properties of a splat (as calibrated for your tablet) |
||
Colors |
Whether more pressure increases the color strength. |
|
Radius |
Whether more pressure increases the radius. |
|
Flow |
Whether more pressure increases the flow. |
|
Opacity |
Whether more pressure increases the opacity. |
|
Radius |
||
Radius |
How many pixels at most the radius of splat can be (if JitterRadius and/or RadiusPressure are enabled). Range: 1 to 1200, Reset: 100 |
A stroke with and without radius jitter, where the jitter is equal to the whole radius of the brush:
|
Squish |
How much to flatten the radius. If the brush tip is a circle, 1.0 is a circle, .5 is an oval half as tall as it is wide. Range: 0.05 to 1.00, Reset: 1.00 |
|
Jitter Radius |
Whether to randomly vary the radius (to the degree specified for the Radius and InnerRadius). |
|
Inner Radius |
How few pixels the radius of a splat can be (if JitterRadius and/or Radius Pressure are enabled). Range: 1 to 1200, Reset: 1 |
|
Rotation |
||
Rotation |
The degree to which the brush rotates to match the direction you're painting (if Align to Stroke is enabled). Range: 0.00 to 360.00, Reset: 0.00 |
|
Align to Stroke |
Whether the brush tip rotates along with the direction you're painting. (With calligraphy, for example, the tip does not align.) |
|
Jitter Rotation |
Whether to randomly vary the rotation. |
|
Jitter Rotation Max |
How many degrees at most to randomly vary the rotation (if Jitter Rotation is enabled). Range: 1 to 360, Reset: 360 |
|
Steady Stroke |
||
Mode |
Whether to use the Off, Distance, or Smoothing mode. Reset: Distance |
|
Delay |
Defines how much delay is used for the brush stroke. In Distance mode, the Delay uses the specified amount of screen pixels, keeping a fixed distance, to define the brush stroke. In Smoothing mode, the Delay uses the moving average of the cursor movement to define the brush stroke. Note: When you move the mouse very fast, Mari gets fewer samples, so the delay looks longer. Range: 0 to 200. Reset: 0.00 |
|
Tail |
Whether to use the No Tail or Meet options for the finishing strokes. • Meet - The brush stroke catches up to the cursor's position when releasing the mouse or pen. • No Tail - The brush stroke stops as soon as the mouse or pen is released, with no catch-up. Reset: No Tail |
|
Tilt |
||
Y Stretch | Stretches the brush splat vertically (Y direction) based on tablet pen tilt. | |
X Stretch | Stretches the brush splat horizontally (X direction) based on tablet pen tilt. | |
Brush Tip | ||
Bitmap |
||
Use Painting |
Click to use the painting in the paint buffer as a brush tip. Mari prompts you to save it either as an .exr or a .tif file (which file format is used depends on the support in your graphics card). Note: EXR files are 16-bit - most other bitmaps are 8-bit. |
|
Path |
Type the path or click the button to select an existing bitmap to use as the brush tip. |
|
Type |
To use an image as the brush tip, you need to set Type to Bitmap. |
|
Geometry |
||
Vertical Shear |
How much to distort the brush tip diagonally, top to bottom (as if pulling opposite corners up and down). Range: -1.00 to 1.00, Reset: 0.00 |
|
Horizontal Shear |
How much to distort the brush tip diagonally, right to left (as if pulling opposite corners right and left). Range: -1.00 to 1.00, Reset: 0.00 |
|
Vertical Scale |
How much to distort the brush tip vertically. Range: 0.00 to 2.00, Reset: to .50 |
|
Horizontal Scale |
How much to distort the brush tip horizontally. Range: 0.00 to 2.00, Reset: to .50 |
|
Noise |
||
Octaves |
Number of applications of noise. Range: 1 to 8, Reset: 4 |
The same brush with the default and maximum noise:
|
Frequency |
How many spikes per octave. Range: 0.00 to 100.00, reset to 1.00 |
|
Scale |
How big the spikes are, as a proportion of the radius (1.00 = twice as big as the radius). Range: 0.00 to 1.00, Reset: 0.00 |
|
Segments |
Lines making up the brush outline, to which noise is applied (4=square, 360=circle). Range: 4 to 360, Reset: 360 |
|
Profile |
||
Profile |
For rendered brushes (see Brush Properties above), alpha profile of the brush tip from center to edge - determines how “hard” or “soft” it is.
In the Curve Editor, to move values along a curve, you can drag any of the points on the curve in any direction, and see the effects in the preview bar below the curve. Click to add a new point, and right-click to invert, select presets, and export and import settings. To remove a point, click on it while holding Ctrl/Cmd. |
Hard and soft brush tip profiles:
|
Bit Depth |
Byte (8-bit), Half (16-bit), or Float (32-bit) It is generally a good idea to use a brush with the same bit depth as the texture you're painting, to avoid stepping. Note that if you use an 8-bit bitmap, it still paints in 8-bit even if you set the bit depth to Half. |
|
Resolution | ||
Height Pixels | Set the height resolution of the brush tip. | |
Width Pixels | Set the width resolution of the brush tip. | |
Scratch pad - shows a squiggle painted with the selected brush. You can also paint directly in the scratch pad (the default squiggle disappears while you enter a stroke). |
Note: The texture properties vary from one painting tool to the other and some tools do not have texture properties. Only the tools containing texture properties are listed below.
