Control (UI) Default Value Function
basePath none Describes the Scene Graph location of the object to constrain.
The basePath parameter options are available in either the
scene graph widget or dropdown menu to the right of the
parameter. For more information on the basePath widget
parameters, see Common Node Widgets on page1.
targetPath none Describes the object(s) location to which the basePath object is
constrained. The targetPath parameter options are available
by clicking Add Locations. For more information on the
targetPath widget parameters, see Common Node Widgets on
page1.
targetBounds box Sets the type of bounds to use for the target object(s).
• box - the field of view is constrained to fit the bounding box of
the target object(s). This can be very useful for shadow maps,
as it produces a tight fitting bounding box.
• sphere - the field of view is constrained to fit a sphere that
encloses the bounding box of the target object(s). This can be
very useful for turntables when you don't want the field of
view to change as the object rotates.
angleOffset 0 Sets the angle added to the FOV during calculation.
allowMissingTargets No When set to Yes, silently ignore the constraint if its target is not
in the Scene Graph.
When set to No, produce an error on constraint resolution if the
target is missing.
Gaffer
The Gaffer node is used to wrap multiple lights into a single node, as well as adding the ability to:
• Use light profiles for different types of light
• Add light rigs to group lights together
• Mute and solo lights and groups of lights
• Link lights to specific geometry
• Add aim constraints to lights
