Houdini 18.5 Executing tasks with PDG/TOPs pdg

pdg.regenerateReason module

Enumeration of possible reasons for a node to regenerate during the cook

Values

pdg.regenerateReason.Always

The node is configured to always regenerate, so it will do so because of that option. If the node is regenerating work items for a different reason it will take priority over this enum entry.

pdg.regenerateReason.Dirty

The node needs to completely dirty itself during regeneration and produce new work items.

pdg.regenerateReason.Full

Something about the node itself has changed, e.g. a parm and the node needs to be regenerated.

pdg.regenerateReason.Propagate

Same as Full, except that if PDG encounters this regeneration status on a node it will also ensure that all outputs are upgraded to the same status if they're set to None.

pdg.regenerateReason.None

The node is not regenerating at all, and its input nodes have also not been invalidated.
