Carbon Actor¶
Description¶
This node creates anchors to the world that can be animated. It can either be a single anchor from a single point or multiple anchors from multiple points contained in a geometry.
The Actor can then be used by a Carbon Joint to attach Carbon Rigid Body nodes to the world.
Use the Houdini handle to adjust the position and orientation of the Actor from within the Houdini Scene View.
Warning
Actor nodes are an experimental feature that are subject to change in future versions.

A Carbon Actor.
Parameters¶
Number Of Objects numobjects
Number of Actor objects created from within this node.
Object Name Prefix objname
Name prefix of the Actor objects created from within this node.
Object Counter Start objStart
Starting index of the Actor objects created from within this node.
Animated Position positionAnimated
Enable animated parameters for this section by evaluating and updating the values at every frame.
Start Pose

Enable ref
Enable/disable the reference pose.
Animated Geometry geometryAnimated

SOP Path soppath
Actor geometry used to provide a set of points (pose) in constraints such as draping. Ignored when used with Carbon RigidBody node.
Prim Group Prefix primgroup
Prefix of the geometry primitive groups that are used to create multiple Actor objects from within this node.
Parameter File¶
Use Parameter File fileOverride
Replace parameter values by expressions fetching the values from the loaded parameter file. Parameter values from the exclusion filter are left unchanged.
File Name fileName
Json file path to save this node’s current parameters to, and load the parameter file from.
Save save
Save this node’s current parameters to the specified file.
Load load
Load or reload the specified parameter file. As the overriding expressions always fetch values from the last loaded parameter file, and not from the file itself, use this button to refresh the loaded current parameter file with the values on disk.
Reload Every Time The Node Is Loaded reload
Automatically reload the parameter file when the scene is loaded. If the specified file cannot be found then the overriding expressions will use the values of the last loaded parameter file instead.
Exclusion Filter exclusionFilter
The exclusion filter allows to select which of the parameters are not to be replaced by the overriding expressions, therefore keeping their original values while all other parameters will evaluate with the values set from the last loaded parameter file.
