Overview
A special node that defines an input to a custom node (a subgraph turned into a node). Place it inside a custom node to expose one input port on the outside. It has no purpose on its own in a regular graph.
Usage tips
- Use it only inside a custom node. Place it in the internal graph where a value
should enter from outside, then connect its
valueoutput to the internal processing. pin_nameandport_typedetermine how it appears outside. Choose the correct type from the start; changing it later disconnects external connections.- Enable
requiredto report an error when the port is unconnected outside (for mandatory inputs such as an image). - Place multiple Input Pin nodes to give a custom node multiple inputs. Remember to manage their order as well.
