Houdini 18.5 Nodes TOP nodes

TOP Fetch Input TOP node

Input to a TOP fetch-ed network

On this page
Since 17.5

This node can be used to receive input data from a TOP Fetch node in a different network. The TOP Fetch node in the original network will write its attributes and input file list to JSON file. The path to that file is available in this node via the $PDG_FETCH_JSON_FILE environment variable.

Tip

The $HH/help/files/pdg_examples/top_topfetch example shows how you can use this node to retrieve input work items from a TOP Fetch node.

Parameters

Generate When

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.

Automatic

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.

JSON Data File Path

The file path to the JSON data pack produced by the TOP Fetch node. The TOP Fetch Input will load the work item attributes and inputs from the file and create a copy of the work item in this node.
