Input
Input
Use Input to define the public entry ports of a reusable subgraph. These ports become the contract parents must supply when instancing the graph.
Availability
This node is available in the free feature set.
Common uses
- Add clear labels to ports so upstream graphs can connect inputs correctly.
- Treat input ports as a stable contract for reusable graph assets.
Input ports
-
None
-
No upstream image input required; this node declares interface ports.
Output ports
- None
Port names can depend on the graph or node configuration.
- Outputs declared interface values into the current graph.
Parameters
This node has no shared processing parameters.
Behavior
- Ports are normalized on load to ensure required defaults exist.
- Graph input handles map to instance input handles by ID.
Common mistakes
- Changing port IDs can break existing graph instance wiring.
- Missing defaults can cause unexpected empty inputs in instances.
