Off This Normal—
When on, lets you set an
approach vector to specify the angle at which the
final approach occu rs. Default=off.
X/Y /Z—Use these settings to specify the final
approach vector in world coordinates. For
example, the vector spe cified by the default
settings of X=0, Y=0, Z=1 means that the delegates
w ill approach the target along the vertical world
axis.
Seed—Affectstherandomnumbersusedto
calculate the Deviation settings.
For similar randomization among different Surface
Arr ive b ehaviors, use the same Seed value.
Co lor Swatch—Shows the color used to draw the
target icon. Default=dark blue.
Display Target—Enables display of the target icon,
which appears during the solution when a new
interim goal is calculated for the delegate. Interim
goals are created when using the Approach group
settings. Default=on.
Target Scale—Specifies t he overall size of the target
icon. Default=5.0.

The Surface Follow behavior moves delegates
with respect to object surfaces, which can be
stilloranimated. Forexample,youcanapply
an animated Noise modifier to a patch grid to
simulate a choppy water surface, and objects
guidedbySurfaceFollowwillstayontop.
Note: By default, a delegate influenced by Surface
Follow picks a direction to move in at any given
frame based on its current facing and the plane of
thefaceit’scurrentlyover.Thusobjectsmoving
up a hill, while seeking a point at the bottom of
the other side of the hill, tend to turn left or right
to skirt the hill, rather than following the upward
slope. You can override this with the Projection
Vector option.
Interfa ce
None (label )—Specifies a single "target" object to
use as a surface. Click this button, and then click
the t arget object in the v iewport. The target name
then appears on the button.
If you’ve selected multiple targets using Multiple
Selection (see next item), the word Multiple
appears on the button. To see which objects are
designated as targets, click the Multiple Selection
button. The Select dialog appears with designated
targets highlighted.
Multiple Selection—Opens t he Select dialog to let
you designate multiple targets.
