User Manual

Path
The Path modifier uses two splines to control the animation of points: an onscreen motion path
(spacial) and a Time spline visible in the Spline Editor (temporal). To animate an object’s position
control using a Path, right-click the Position control either in the Inspector or in the viewer and
select Path from the contextual menu. This adds a keyframe at the current position. You can
begin creating a path by moving the playhead and dragging the center position control in the
viewer. The Spline Editor shows a displacement spline for editing the temporal value, or
“acceleration,” of the path.
Controls
Controls Tab
The Controls tab for the path allows you to scale, reposition, and rotate the path. It also
provides the Displacement parameter, allowing you to control the acceleration of an object
attached to the path.
Center
The actual center of the path. This can be modified and animated as well to move the entire
path around.
Size
The size of the path. Again, this allows for later modification of the animation.
X Y Z Rotation
The path can be rotated in all three dimensions to allow for sophisticated controls.
Displacement
Every motion path has an associated Displacement spline in the Spline Editor. The
Displacement spline represents the position of the animated element along its path,
represented as a value between 0.0 and 1.0. Displacement splines are used to control the
speed or acceleration of an object’s movement along the path.
