Bases: MayaInstancePlugin
Gather members for instances and pre-defined attribute
This collector takes into account assets that are associated with an objectSet and marked with a unique identifier;
Identifier
id (str): "ayon.create.instance"
Limitations
- Does not take into account nodes connected to those within an objectSet. Extractors are assumed to export with history preserved, but this limits what they will be able to achieve and the amount of data available to validators. An additional collector could also append this input data into the instance, as we do for
pype.rig with collect_history.
