UsdInActivationSet

Activates or deactivates scopes within the USD stage using the session layer. Deactivated scopes (and their children) aren't include in stage composition, so it's often more efficient to deactivate something unused there instead of Katana's Prune or Isolate nodes. Katana doesn't read USD data from locations that are removed by Prune or Isolate nodes, but they are still considered during USD stage composition.

Control (UI)	Default Value	Function
locations	None	One or more Katana scenegraph locations loaded from a UsdIn node.
