Switch TOP node

Switch which between network branches

On this page

Parameters
Examples

This node can be used to switch between input network branches based on the Select Input parameter. The node network will behave as if the selected input branch is wired directly into the node on the switch’s output.

This node does not generate any work items.

Parameters

Select Input

Selects which input branch is active. Other branches will not be evaluated when cooking the TOP graph.
