brushes are a brush type that provide special features not available
with other Paint Effect brush types. Mesh
brushes render using polygonal triangles rather than brush stamps.
As a result, mesh strokes can be more accurately texture-mapped
for realistic results. They also appear more realistic compared
to other brush types whether they are viewed close-up or from a
mesh brush stroke can also be converted to a polygonal surface in
the Maya scene. Once the stroke is converted to polygons, the resulting
polygons can be modified using any of the Maya polygonal modification
tools and utilized like any other polygonal surface (animation,
rendering, and so on)
In this section, you
are introduced to mesh brushes and learn additional techniques related
to the various brush and stroke attributes. You learn how to:
- Understand the structure of strokes with
- Modify a variety brush tube attributes.
- Convert the mesh brush stroke to polygons.
- Modify the converted mesh using construction
- Render the polygonal meshes.
To select a mesh brush preset from the Shelf
File > New Scene.
A new empty scene is
- 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 Teapot Brush.
the scene view, the cursor changes to a sphere icon indicating it
is set to paint a stroke. The Teapot Brush is
a mesh brush type.
- In the scene view, drag your mouse or
stylus along the ground plane to create one short stroke.
- Dolly and tumble the view to see the
wireframe version of the stroke.
The teapot stroke displays
three wireframe tubes to represent the teapot. These tubes represent
the body, spout, and handle for the teapot.
Effects uses a plant or tree archetype to represent the
various tube attributes. If you envision how a plant or tree has
a trunk, out from which branches, leaves, flowers, and buds grow,
you understand how each attribute is controlled in the attribute
center vertical line represents the main tube, whose attributes
are found in the Creation tab of the attribute
editor. The diagonal and semicircular lines represent the Leaves and Flowers tube
attributes for the spout and handle of the teapot.
To render the paint effects stroke
- In the main menu, select
Window > Rendering Editors > Render Settings (or
click the Render Settings icon on the
Status Line) to display the Render Settings window.
- In the Render Settings window,
do the following:
- Select Maya Software from
the Render Using drop-down list.
- In the Image Size section,
select 320×240 from the Presets drop-down
- From the Status Line,
click the Render Current Frame button.
renderer executes, renders the paint stroke, and then displays the image
in a Render View window.
- Close the Render View window.
Mesh brush types are
useful for representing hard surfaces compared to other brush types
(the teapot is one example).
