Syntax
UCLASS&40;&41;
class UUsdTransactor : public UObject
Remarks
Class that allows us to log prim attribute changes into the unreal transaction buffer. The AUsdStageActor owns one of these, and whenever a USD notice is fired this class transacts and serializes the notice data with itself. When undo/redoing it applies its values to the AUsdStageActors' current stage.
Additionally this class naturally allows multi-user (ConcertSync) support for USD stage interactions, by letting these notice data to be mirrored on other clients.
