This node allows users to directly author an APEX graph in the APEX network view. The parameters on this node provide utilities to help with common APEX graph authoring operations.
The input to this node can be a graph geometry or data in a character folder structure.
See APEX graph basics and graphs for numerical operations for more information on creating graphs in the APEX network view.
Parameters ¶
Reset
Clears the graph geometry.
Edit Graph 
Opens the APEX network view.
Error Handling
Provides the option to determine whether the graph is compilable.
Ignore
Does not compile the graph.
Report as Warnings
Compiles the graph and adds a warning to the APEX Graph SOP for each graph compilation error encountered.
Graph Path
The path to the rig in the character folder structure.
Merge Graph
Merges an APEX rig graph from another SOP into this node.
When the dialog comes up, you can either choose from the list of nodes, or select the SOP in the network editor, which automatically selects the corresponding node in the dialog.
As Subnet
When turned on, the graph from Merge Graph is merged into this node as an APEX subnet node.
Import SOP Nodes
Imports compilable SOPs into this node’s APEX graph. APEX nodes can only be verbs, so only compilable SOPs can be imported into an APEX graph. In the dialog, you can select multiple nodes by holding ⌃ Ctrl while selecting. The parameters on the imported graph nodes are set to the same values as the original SOP node parameters.
Add Missing APEX Convert Nodes
Adds conversion nodes where possible for all wires in the graph that connect ports with different types. Changes made are written to the comment on the node.
Update APEX Node Type Names
Updates all nodes with outdated type names to the current names. (The outdated type names are maintained for backwards compatibility). The updated graph may no longer load in older versions of Houdini.
These rigging scripts are utilities based around the KineFX skeleton.
Skeleton Path
The path to the skeleton in the character folder structure.
Import KineFX Skeleton
Creates an FK hierarchy of TransformObject graph nodes corresponding to the selected KineFX skeleton. A TransformObject node is created for each joint in the skeleton.
When the dialog comes up, you can either choose the skeleton from the list of nodes, or select the SOP in the network editor, which automatically selects the corresponding node in the dialog.
Update Rest Transforms From Skeleton
Uses the transforms of the selected KineFX skeleton to update the rest transforms of the FK hierarchy previously created by Import KineFX Skeleton. The names of the TransformObject nodes must match the skeleton joint names for this to take effect.
When the dialog comes up, you can either choose the skeleton from the list of nodes, or select the SOP in the network editor, which automatically selects the corresponding node in the dialog.
Add SetPointTransforms
Takes the selected TransformObject nodes in the graph, connects them to a new SetPointTransforms node, and outputs a modified skeleton geometry. This updated graph can be used to transform a skeleton. See APEX geometry deformation for an example of a similar graph.
-
Select the TransformObject nodes in the graph.
-
Click Add SetPointTransforms.
A skeleton input is promoted in the graph (the skeleton is connected to the parms input node), a SetPointTransforms node is added to the graph with its input ports named according to the TransformObject names, and the same skeleton with its transforms updated is output.
Save to Disk
Saves any subnets as a subgraph in the Output File.
Output File
The file to save the subgraph to. This overrides any existing graphs saved to the file.
Name Space
When turned on, adds the specified namespace to the saved subgraph. If you search in the APEX network view TAB menu, the saved subgraph will be listed with the namespace, for example, <namespace>::<subgraph_name>.
Inputs ¶
Input
The APEX graph geometry used as the initial graph to edit. After the graph is edited, the input is ignored. This input can also be a packed folder structure.
Outputs ¶
Output
The updated APEX graph geometry.

APEXGraphExamples Example for APEX Graph geometry node
This example demonstrates how to create APEX graphs that perform basic numerical operations, as well as build functionality for the animate state, including controls, hierarchies, constraints, and geometry deformation.
