Houdini Digital Asset Node

This node drives one Houdini Digital Asset (HDA). The node takes the HDA file path and asset name as inputs. When valid HDA file and asset name are used as inputs, a Houdini Node is created and the node inputs and outputs are dynamically updated to expose the HDA’s reflected inputs, outputs and exposed parameters.

Installation

To use this Node, you must enable omni.houdini_engine.omnigraph in the Extension Manager.

Inputs

Name	Type	Description	Default
hda_file_path	string	The HDA File Path
hda_asset_name	string	The HDA Asset Name for that node
do_collect_geometry_attributes	bool	Collect all the primitive and detail attributes	True
trigger_node_cooking	bool	Trigger a cooking operation for this node	False
interactive_cooking	bool	Cook HDA node on every UI parameter change	False
use_builtin_hda_sources	bool	Search in the Houdini builtin assets when instantiating an asset based on the asset name. If checked, the input ‘hda_file_path’ is not taken into account when creating an asset.	False

do_collect_all_detail_attributes	bool	Collect all the geometry detail attributes.	False
export_input_bundle_attributes	token	Extracts the value of specific input bundle attributes and forwards them to the proper output bundle.
exec_tick	int	Private field.	0

Outputs

Name	Type	Description	Default
node_absolute_path	token	The Houdini node relative path in the Houdini Engine Session.
status	int	The status of the node’s latest execution (during cook or compute()). 0 for success, > 0 for any failure.
