Like a traditional paint
program, Paint Effects allows you to
use a brush and paint strokes. In Paint Effects,
the brush and stroke have unique qualities and characteristics.
A brush contains
the various attributes that define the appearance and behavior of
the paint. The template brush settings define
the initial settings for a brush.
When you drag the Paint
Effects brush, you create a path for the brush called the
stroke is a 3D curve (or collection of curves) with attributes that
define how the paint is applied along the stroke path. You can paint
strokes directly in the 3D scene or on objects.
When you select a brush preset from the shelf
or from the Visor, that brush is copied to the template brush. Any
changes you make to the template brush settings affect what the
next stroke looks like, but they do not affect any previously painted
To select a Paint Effects preset
brush from the Shelf
- From the Toolbox panel
layout shortcuts, select the Single Perspective View.
- From the Shelf, select
the Paint Effects tab to display
the Paint Effects preset brushes.
- From the Paint Effects shelf,
select the Daisy Large Brush.
In the scene view, the
cursor changes to a red circle with a vertical line indicating it
is set to paint a stroke. The circle indicates the width of the brush
path. With some types of strokes, this path will appear as the width of
the actual paint; with other stroke types, it indicates the width
of the tube seeding path, for example, plants, trees, etc.
settings of the preset brush you select are copied to the template brush.
The template brush settings are used when a paint stroke is drawn. If
you want to modify the brush presets before you begin to paint,
you must edit the template brush after you’ve chosen the preset

default, the brush cursor moves along the ground plane. The ground plane
lies in the X, Z dimension. This is the default behavior for the
brush cursor. If you draw a paint stroke, it is applied to the ground
plane (X, Z).
To paint 3D strokes in the scene view
the Daisy Brush selected, draw
one short paint stroke on the ground plane using one of the following
- Drag the stylus across the tablet while
exerting slight pressure on the stylus as you move it.
- Drag the mouse while pressing the left
One or more wireframe
daisy stalks appear in the scene view along the path of the paint
stroke. When you paint a stroke in the scene view it initially appears
as a wireframe. Paint is not applied to the stroke until it is rendered.
stalks that extend out of the curve or stroke are called tubes.
In Paint Effects, strokes are
either simple strokes or strokes with tubes.
Because the stroke has
a curve associated with it, you can move, scale, or rotate the stroke
like other objects in the scene. You can edit the curve to modify
the shape of the stroke path.
- Dolly and tumble the scene to better
view these strokes with tubes in 3D.
- Select the Move Tool from
A move manipulator icon
appears at the X, Y, Z origin. (If the move manipulator does not
appear, you can click on the stroke to reselect it with the Move
- In the scene view, drag any of the Move
Tool manipulator arrows to reposition the stroke.
Each time you paint a
stroke, Paint Effects creates a new
brush and stroke node and attaches them to the stroke that is created.
You can modify these brush and stroke nodes once they’ve been created.
To edit these brush or stroke attributes, you use the Attribute

daisy stroke. The various attributes for the stroke appear under different
tabs. Each tab represents a node associated with a specific set
- Click on the strokeDaisyLarge1 tab to
see its attributes.
This tab contains information
related to the transform node, because the most important attributes
on this tab control the stroke’s curve transformation.
- Under Transform Attributes,
set Rotate to be 0, 90, 0.
The stroke is rotated
90 degrees about the Y axis.
- Click the strokeShapeDaisyLarge1 tab
to see its attributes.
This tab is called the
stroke attribute node because the attributes establish the paint
stroke’s properties when the stroke is first created.
the End Bounds section by clicking
the arrow to see the Min and Max
Clip specifies the start of the stroke along the path. Max
Clip specifies the end of the stroke along the path.
- Drag the Max Clip slider
from its present value of 1.0 to a value of 0.1.
The stroke path is shortened.
Min and Max
Clip can be animated to create the effect of the paint
advancing along a path.
- Drag the Max Clip slider
back to its original value of 1.0.
- Click the daisyLarge1 attribute tab to
see its attributes.
This is the node that
contains attributes related to the paint brush associated with the
the Global Scale attribute to 6.0.
The daisies scale larger
along the stroke’s path.

The daisies lay on the
ground plane, as if wilting, with the increased gravity.

The last tab in the Attribute
Editor is the time node. The time node is used for animation
and dynamics. You do not use this node in this lesson.
