Relative Reference
This mode is similar to Use Start Position. It enables you to reference an element relative to the object
that owns the XPresso tag. Unlike the Use Start Position mode, you enter a path that gives the node
instructions on how to reach the element. The starting position is the object that owns the tag. For
example, the path ‘UPPDN’ stands for ‘Up, Previous, Previous, Down, Next’, where Previous and
Next represent a jump to the previous or next element on the same hierarchical level. Up and Down
represent jumps one level up or one level down the hierarchy. The advantage of a relative reference
is that it enables you to transfer the Object node from one hierarchy to another without problems.
Edit the path using the Path box.
Start Position
This denes the Start Position when Reference Mode is set to Use Start Position. The setting is relative
to the object that owns the XPresso tag. For example, if you set Start Position to First In This Level, the
node references the rst element on the same hierarchical level as the object that owns the tag.
 This Object: The object that owns the tag.
 Up In Hierarchy: Chooses the rst object one level up the hierarchy.
 Down In Hierarchy: Jumps to the rst object one level down the hierarchy.
 Successor On This Level: Chooses the next object on the same hierarchical
level.
 Predecessor On This Level: Jumps to the previous object on the same
hierarchical level.
 First On This Level: Chooses the rst element on the same hierarchical
level.
 Last On This Level: References the last element on the same hierarchical
level.
 First In Scene: Chooses the rst object in the scene.
 Last In Scene: Jumps to the scene’s last element.
Start Distance
With some Start Position modes you might want to jump several steps in the hierarchy in one go.
In such cases, use Start Distance as a multiplier for the Start Position. For example, to reference
an object that is three positions after the object that owns the XPresso tag, set Start Position to
Successor On This Level and set Start Distance to 3.
