Defines the size, density, and stroke characteristics of the paint tool. The paint tool is primarily used to apply properties to points, as in the case of weight mapping — see Using Brush-based Tools [Commands and Tools].

Weights

Controls the paint mode, the size of the tool's selection area, and other options. The size of the tool's selection area is determined by the brush radius, whereas the density of the brush affects the amplitude of the property applied to the selected area. A graphic depiction of the brush, shown at the bottom of the Brush section, updates in size and density as you manipulate the controls.

Weight Paint Mode

Controls the behavior of each paint stroke:

Normal modifies the current weight based on the Opacity value:
- To increase weight, click and drag.
- To decrease weight, Shift+click and drag or right-click and drag.
- To smooth weights, Alt+click and drag.
Set Weight sets the weight to the Opacity value.
Smooth Weight blends weight values. You can also smooth in Normal mode by pressing the Alt key.
Reveal erases paint strokes to reveal the underlying base weight map.

Brush

Radius	Controls the radius of the brush stroke, in SOFTIMAGE units.
Opacity	The amount of weight to add in each brush "stamp" in a stroke.
Hardness	Controls the proportion of the brush diameter that is solid.
Softness	Controls the gradient fall-off rate in brush density from completely solid to transparent. A lower value creates a more diffuse brush stroke.
Spacing (%)	Controls the distance between each brush "stamp" in a stroke.
Normalize	Automatically ensures that envelope weights always add up to 100. You can temporarily turn this off to remove some weight from an existing deformer in order to add weight for a new one.

Surface Coverage

Coverage

The maximum angle the brush is allowed to wrap around the object, relative to the middle of the brush. A value of 180 will cause the brush to paint completely around an object; a much lower value will cause the brush to paint only on the upper surface of the object.

Pen Tablet Pressure

Controls whether the pen pressure affects Opacity or Radius when using a tablet as an input device.

This works on Windows only. It also requires that the XSI_ENABLE_WINTAB_SUPPORT environment variable be set, which may affect performance. See Environment Variables.

Radius

Controls the size of the brush stroke.

Refresh

Controls how the scene updates as you are painting:

On Mouse Up: Softimage waits until you have finished a paint stroke and released the mouse button before updating the scene. You can see the color of a paint stroke on a weight map as you paint, but you won't see the result of, for example, a Push operator on the object's deformation until you release the mouse button. This method provides faster interaction.
Interactive: Softimage updates the scene as you paint a stroke. This method lets you see the results as you paint, but may slow down your computer.

Show Property Maps	Controls the display of weight maps while the paint tool is active. If it is off, maps are displayed only while the mouse button is held down during a paint stroke.
Pick Weight Map	Opens a transient explorer so you can pick the weight map you want to modify.

Vertex Colors

Controls properties for painting on Color at Vertices (CAV) maps.

Color Paint Method

Choose a painting method:

Brush: uses the brush to paint on the object. The brush attributes are defined by the Brush settings.

Raycast: uses the mouse pointer to paint on the object. Paint interactions affect only the vertex under the pointer, and adjacent vertices as defined by the Bleeding options.

Bleeding (Raycast mode only)

Vertex	Toggles whether the brush color will spread from the painted vertex into adjacent polygons.
Polygon	Toggles whether the brush color will spread from the polygon into adjacent polygons.

Brush

Radius	Controls the radius of the brush stroke, in SOFTIMAGE units. You can interactively adjust the radius in the active 3D view by holding down R and dragging.
Opacity	The amount of color to add in each brush "stamp" in a stroke.
Hardness	Controls the proportion of the brush diameter that is solid.
Softness	Controls the gradient fall-off rate in brush density from completely solid to transparent. A lower value creates a more diffuse brush stroke.
Spacing (%)	Controls the distance between each brush "stamp" in a stroke.
Selection	If you're painting on an object while some of its components are selected, you can choose how the vertex painting tool treats the selected components. Ignore: painting on the object affects the entire object, irrespective of the selection. Use: painting on the object only affect the selected components. Exclude: painting on the object affects everything but the selected components.

Pen Tablet Pressure

Opacity

If you are using a pen and tablet instead of a mouse to paint, uses the pressure to control the overall density of the brush stroke.

Vertex Color Display Property

Specifies the vertex color property to paint on. See Specifying Parameter Maps or Vertex Colors in Property Editors.This overrides the default vertex color property set in the Material Node Property Editor.

Show Property Map

Displays the vertex color property in the viewports.

Color Paint Mode

Mode drop-down list

Specifies the painting color mode:

RGB: painting on the object affects only the RGB channels.

Alpha: painting on the object affects only the alpha channel.

RGB+Alpha: painting on the object affects both the RGB and alpha channels.

Luminance: painting on the object affects its luminance.

Color Correction: painting on the object modifies the current vertex according to the settings in the Color Correction options.

Smooth: painting on the object smooths the transition between colors on adjacent vertices.

Brush Color

When the Color Paint Mode is set to RGB, Alpha, or RGB+Alpha, specifies the brush color using the palette, color editor, or RGBA sliders.

Color Correction

When the Color Paint Mode is set to Color correction, these options are displayed below the Color Paint Mode drop-down instead of the color selection tools. Painting on the object's CAV in color Correction Mode modifies the current vertex color according to the settings below.

Hue	Controls a 360 degrees hue shift through the HLS color space spectrum without modifying the intensity or saturation of the color.
Lum	Adjusts the level or luminance of a color. Similar to intensity or brightness.
Sat	Adjusts the saturation, or amount of "pigment," in a color.

Symmetry

Controls how painting is affected when Sym is on in the Transform panel.

Use Local Object Symmetry Plane	Uses the object's local center and whichever symmetry plane is currently active to determine symmetry. To set the active symmetry plane, right-click on Sym and choose an option.
Use Symmetry Maps	Uses any symmetry map applied on the object to determine symmetry.

If both options are on, symmetry maps take precedence. This allows you to symmetry maps wherever they exist and the object's local symmetry plane wherever there are no clusters with symmetry maps.
