TSwitchNode | Unreal Engine 5.6 Documentation

API > API/Plugins > API/Plugins/GeometryFlowCore

TSwitchNode selects one of N inputs and provides it as an Output. This allows for a minimal amount of branching / control-flow in a fixed GeometryFlowGraph. Only the active Input is evaluated.

The number of inputs is defined in the template type, eg TSwitchNode is a switch node with 3 possible inputs. Dynamic number of inputs cannot be easily supported without changes at the graph evaluation level.

Use UpdateSwitchValue() to select the active switch Input
