The Subnet Input node is a special node that can only be used inside a Subnet. It acts as the placeholder for all incoming connections from the parent graph.
Purpose
The Subnet Input node acts as the entry point for data coming from the parent graph. When you connect nodes to the parent Subnet node, their combined output becomes available from this node’s output handle, allowing you to use external data within your subnet’s logic.
A subnet is not required to use its input; it can also generate all of its data internally.
- It has no input handles because it is the input.
- It can only be created from the node search menu when you are inside a
Subnet. It is also automatically created when you make a newSubnet.
A Subnet node encapsulates its own internal graph. Data can pass from the parent graph into the Subnet Input, get processed by custom logic, and then return to the parent graph via the Subnet Output.
