Interface: custAttribCollapseManager
The custAttribCollapseManager Core Interface provides controls over the behavior of Custom Attributes when the modifier stack is being collapsed.
Properties:
custAttribCollapseManager.surviveState : boolean : Read|Write
When set to true, Custom Attributes will survive collapsing the Modifier Stack - they will be copied onto the base object.
When false, Custom Attributes will be lost after collapsing.
