This node reads a USD file or LOP node and creates work items based on search criteria. The search is done on the composed stage of the specified input USD or LOP.
The name of the primitive.
The full path to the primitive.
Determines when this node will generate work items. You should generally leave this set to "Automatic" unless you know the node requires a specific generation mode, or that the work items need to be generated dynamically.
All Upstream Items are Generated
This node will generate work items once all of the input nodes have generated their work items.
All Upstream Items are Cooked
This node will generate work items once all of the input nodes have cooked their work items.
Each Upstream Item is Cooked
This node will generate work items each time a work item in an input node is cooked.
The generation mode is selected based on the generation mode of the input nodes. If any of the input nodes are generating work items when their inputs cook, this node will be set to Each Upstream Item is Cooked. Otherwise, it will be set to All Upstream Items are Generated.
The input the node reads to create the work items.
Determines the source of the USD file or LOP node.
Custom File Path
Uses the USD file specified by the custom file path.
Upstream Output File
Uses the output file produced by the upstream work item as the path to the USD file.
Reads the composed stage from the specified LOP node.
The data tag that identifies the result from the upstream work item.
This parameter is only available when USD is set to Upstream Output File.
The path to the USD file to be read.
This parameter is only available when USD is set to Custom File Path.
Add File Path to Outputs
When USD is set to either Custom File Path or Upstream Output File, this parameter determines whether or not the file path should be added as an output file on work items in this node.
The path to the LOP node from which to read the composed stage.
This parameter is only available when USD is set to LOP Node.
The search criteria the node uses to create the work items.
The Primitive Matching Pattern to apply to the specified input stage.
Determines how attribute keyframe values from the input stage are interpolated.
Work Item Frame
Uses the frame on the generated work item.
Uses the given time in seconds.
Uses the Houdini playbar time.
Strip Layers Preceding Layer Break
When on, any layers preceding a Layer Break LOP node connected directly or indirectly to the requested LOP node will be stripped from the USD stage before importing the stage.
This parameter is only applicable when the input is a LOP node.
When on, adds the specified string attribute to the primitive path.
When on, adds the specified string attribute to the primitive name.
Specifies the attribute pattern to use to identify which USD attributes to extract and then extracts those attributes.
:type syntax is not supported.
