unreal.RigVMController

class unreal.RigVMController(outer=None, name='None')

Bases: unreal.Object

The Controller is the sole authority to perform changes on the Graph. The Controller itself is stateless. The Controller offers a Modified event to subscribe to for user interface views - so they can be informed about any change that’s happening within the Graph. The Controller routes all changes through the Graph itself, so you can have N Controllers performing edits on 1 Graph, and N Views subscribing to 1 Controller. In Python you can also subscribe to this event to be able to react to topological changes of the Graph there.
