Spline Path
By animating the Spline Path parameter you can change which spline the
object is aligned to during the animation.
Select the relevant Align To Spline tag and then drag the Spline object from the Object manager and
drop it into the Spline Path box on the Attribute manager’s Tag page.
Rail Path
You can optionally use a rail path. Drag the spline that you want to act as the rail from the Object
manager into the Rail Path box on the Attribute manager’s Tag page. This has a similar effect to the
Align To Path tag in the sense that the object’s Z-axis remains parallel to the spline’s tangent at all
times.
Tangential
If you enable Tangential, the effect is similar to that of the Align To Path tag, i.e. the object’s X, Y or
Z-axis is aligned to the rail path.
Position
If you animate the expression’s Position parameter, the object follows the path using the axis dened
by Axis. If the object should follow, say, only the rst half of the spline, animate Position from 0% to
50%. For more details on how to animate this Position parameter, see the Timeline chapter and/or
the Attribute Manager chapter.
