Base Scale—
Altersthescaleofthesourceobject,
affecting each duplicate identically. This scale
occurs before any other t ransforms.
Vertex Chaos—Applies a random perturbation to
the vertices of the source object.
Animation Of fset—Lets you specify the number of
frames by w hich each s ource object duplicate’s
animation is offset from the previous duplicate.
You can use this feature to produce wave-ty pe
animation. At the default setting of 0, all duplicates
move identically.
Distribution Ob ject 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 perpendicular to its associate face, ver tex,
or edge in the distribution o bject. When off, the
duplicates maintain the same orientation as the
original source object.
Use Sel ect ed Faces On l 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 t he
geometry of the distr ibution object determines t he
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 distribut ion 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. T he editable field specifies how many
facestoskipbeforeplacingthenextduplicate.
When set to 0, no faces are sk ipped. When set to 1,
every other face is skipped, and so on.
Random Faces—Appliesduplicatesrandomlyover
the sur face of the distribution object.
Along Edges—Assignsduplicatesrandomlytothe
edges of the distr ibution object.
