Keep the selected node from updating when its
inputs change.
Blocking.
Make the node active again.
Normal.
Notes
The
“HasNoEffect” state has a different meaning for each node type.
Some node types do not implement the state, in which case the state
acts just like “Normal”.
The
“Waiting” node states are used internally by Maya to keep track
of nodes that are waiting for a view update in the Hypergraph.
You should not normally set nodes to a “Waiting” state.
