To open and close hierarchies:
 Click the icon to the left of the node or XGroup name.
To create a new empty XGroup:
 Right-click (Windows) or Command-click (Mac OS) on the root XGroup’s name
in the XPresso Manager window and choose New XGroup > Empty XGroup
from the context menu.
To control the order of evaluation:
 Drag a node or XGroup name and drop it in a new position.
 The top-most elements in the XPresso manager are evaluated rst. This order
is especially important when the result of a node is passed to another XGroup,
otherwise the values passed may be incorrect and the expression may fail to
work as intended.
The XPresso Pool
The XPresso Pool provides a quick way to add nodes to the XPresso Editor. The XPresso Pool contains
all of the CINEMA 4D nodes, to which you can add your own pools, where each node is congured to
suit your needs. For example, suppose you often need to create a Math node for integer subtraction
(Data Type set to Integer and Function set to Subtract). Rather than change these parameters manually
each time you need to create such a node, you can add the congured node to the XPressoPool. The
next time you need the node, you can drag it from the pool and drop it into the XPresso Editor, already
set up for integer subtraction.
To open the XPresso Pool:
 The XPresso Pool is integrated into the XPresso Editor by default. However,
should you undock and close the pool, you can reopen it by choosing Custom
> XPresso Pool in the XPresso Editor.
