Scatter Compound Object 321
Base Scale—
Altersthescaleofthesourceobject,
affecting each duplicate identically. This scale
occurs b efore any other transforms.
Vertex Chaos—Applies a random perturbation to
the vertices of the source object.
Animation Offset—Lets you specify the number of
frames by which each source object duplicate’s
animation is offset from the previous duplicate.
You can use this feature to produce wave-type
animation. At the default setting of 0, all duplicates
move identically.
Distribution Object Parameters group
These options affect how the duplicates of
the source object are arranged, relative to the
distribution object. These options have an effect
only when a distribution object is used.
Perpendicular—When on, orients each duplicate
object per p endicular to its associate face, vertex,
or edge in the distribution object. When off, the
duplicates maintain the same orientation as the
original source object.
Use Sel ected Fa ces O nl y —When on, limits
distribution to the selected faces passed up the
Stack. Perhaps the easiest way to do this is to use
the Instance option when picking the distribution
object.YoucanthenapplyaMeshSelectmodifier
to the original object and select only those
faces you want to use for the distribution of the
duplicates.
Distribute Using
The following options let you specify how the
geometry of the distribution object determines the
distribution of the source object. These options are
ignored if you’re not using a distribution object.
Area—Distributes duplicate objects evenly over the
total surface area of the distribution object.
Objects distributed over a spherical surface with Area turned on
Even—Dividesthenumberoffacesinthe
distribution object by t he number of duplicates,
and skips the appropriate number of faces in the
distribution object when placing duplicates.
Sk ip N—Skips N number of faces when placing
duplicates. The editable field specifies how many
facestoskipbeforeplacingthenextduplicate.
When set to 0, no faces are skipped. When set to 1,
every other face is skipped, and so on.
Random Faces—Appliesduplicatesrandomlyover
the surface of the dist ribution object.
Along Edges—Assignsduplicatesrandomlytothe
edges of the distr ibution object.
