on the intended use of your polygonal model, you may want a low
resolution version, a high resolution version, or both. In Maya,
its easy to increase the resolution of a model using the Smooth feature
Mesh > Smooth).
In addition, you can
preview a higher resolution version of the mesh using either Smooth
Mesh Preview or the
Proxy > Subdiv Proxy feature.
You can then view and edit the low resolution and high resolution
smoothed version of the mesh separately or simultaneously.
Mesh Preview lets you quickly preview how your mesh will
appear when smoothed.
Proxy feature links the original and the high resolution smoothed
versions via construction history, you can make changes to the low
resolution version and immediately see the effect on the high resolution smoothed
In this lesson, you’ll
use Subdiv Proxy to work with your
To create a high resolution smoothed
model using Subdiv Proxy
- Right-click the mesh, change the selection
mode to Object, and then select the
Proxy > Subdiv Proxy > , and
set the following:
- Division Levels:
- Mirror Behavior: None
- Subdiv Proxy Shader: Keep
- Click the Smooth button.
A higher resolution,
smoothed copy of the helmet mesh is created in the same position
as the original mesh. It is possible to see the two versions in this
position (and you can toggle the display to show either or both)
but in this lesson you’ll select the high resolution version and
move it slightly to the left.
NoteThe two versions
of the model are also grouped into the same node hierarchy when
the Subdiv Proxy operation is performed.
- Select both the low and high resolution
versions of the mesh in Object Mode.
- Press the ‘ key (located to the left
of the 1 key) to toggle the display between the low and high resolution
Toggling the display
between the two versions is useful when you want to view one or
- Press the ~ key to toggle the display
so that both are visible again.
Proxy Display (‘) and the Both Proxy and
Subdiv Display (~) display items are also available from
within the Proxy menu.
- Select only the smoothed version of the
mesh in Object Mode and move it to
the left about 25 units (X = -25).
As you edit the low resolution
version of the helmet mesh you’ll see the resulting updates on the
smoothed version beside it.
