Houdini 18.5 Executing tasks with PDG/TOPs pdg

pdg.FileDependency class

Represents a node’s dependence on the existence of an external file.

Inheritence

The key property contains the file path. The given file will be copied to the PDG working directory before the first work item from the node is scheduled to execute.

This can be used to ensure that supporting files like digital assets and custom scripts are available for the work item job.

The specified paths can be absolute or relative to HOUDINI_PATH.
