Filter
The base type for all nodes which are capable of choosing which scene locations a FilteredSceneProcessor applies to.
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
enabled
The on/off state of the filter. When it is off, the filter does not match any locations.
out
The result of the filter. This should be connected into the “filter” plug of a FilteredSceneProcessor.
