UPercent—
Moves the object along the U

percentage of the U distance. This s pinner defaults
to a setting of 50 percent, which places the object

percent places the object at the left edge of the
gizmo patch, as seen from the viewport where the
patch was created.
UStretch—Scales the object along the U
(horizontal) axis of the gizmo patch.
VPercent—Moves the object along the V (vertical)
axis of the gizmo patch, based on a percentage of
the V distance. A setting of 0 percent places the
object at the bottom of the gizmo patch.
VStretch—Scales the object along the V (vertical)
axis of the gizmo patch.
Rotation—Rotates the modified object with respect
to the gizmo patch.
Move To Patch—Clicking this button moves the
object from its original position to the p atch objec t
you are using for deformation. This button is only
available with the PatchDeform (WSM).

The PathDeform modifier deforms an object
using a spline or NURBS curve as a path. You can
move and stretch the object along the path, and
rotate and twist it about the path. There ’s also a
world-space modifier version. See
PathDeform
(WSM) (page 1–533)
.
PathDeform creates a wiggle for the snake.
Using a Path to Defor m an Obj ect
Generally, you us e the PathDeform modifier
when you want to keep an object in place while
deforming to a path. Use the PathDeform
world-space m odifier when you want to move an
object to a path while keeping the p ath in the same
world space.
The PathDeform (WSM) modifier replaces the
space-warp version that shipped with previous
versions of 3ds Max, and is incompatible with
previous versions. See
PathDeform (WSM) (page
1–533)
for details on how to fix incompatibilities
from the previous version.
To use the PathDeform modifier, you apply it, then
click the Pick Path button and select a shape or
curve consisting of a single open or closed spline.
Once the object is assigned to the path, you can
adjust the parameters to deform or animate the
object along a gizmo copy of the path.
