Displacement Painting Brushes
The tools for sculpting in Silo are called displacement painting brushes. You can
see the available default brushes by selecting
Editor/Options
>
Brush Editor
or
Modify
>
Paint Displacement
>
opt
or by pressing
Shift
T
( Figure 3.21 ).
There are six main brush functions and seven default brushes, although you
also have the option to create and save your own derivatives of the defaults. You
enter the tool by selecting
Modify
>
Paint Displacement
or by pressing
T
.

To get familiar with each of the functions, it is probably best to load a custom
primitive base bust (
Create
>
Custom Primitives
>
Base Bust
), subdivide a
few times, and then try each of the brushes. Some, you'll notice, have a much
more dramatic impact than others. Also important to note is that most of the
brushes have an alternate or opposite ef ect. To get the basic ef ect you'll use
the
Left Mouse Button
. To get the alternate ef ect you use the
Right Mouse
Button
. The size of the brush can be adjusted by holding the
Middle Mouse
Button
or
Scroll Wheel
and moving the mouse (or with the
Radius
value in
the settings screen). In general, you should see the following results:
●
Push
(or
Sharp Push
)
Brushes
: These brushes add volume to the mesh. As
you can see in Figure 3.22a, we've drawn a circle around the eye with the
mouse while holding down the left mouse button. Alternatively, using the
right mouse button will carve into the model.
●
Smooth Brush
: The
Smooth Brush
, much like the
Smooth
command,
helps put the object in order by evening out variation, diminishing the
impact of other sculpting tools, and decreasing volume. The right-click
alternative adds noise, making the mesh rougher. In Figure 3.22b, using
the
Smooth Brush
we have eliminated much detail from the base bust.
●
Move Brush
: The
Move Brush
is much like
Soft Selection
combined with
Tweak
. It allows you to grab a chunk of polygons and move them around
