class URigVMPin : public UObject

Remarks

The Pin represents a single connector / pin on a node in the RigVM model. Pins can be connected based on rules. Pins also provide access to a 'PinPath', which essentially represents . separated list of names to reach the pin within the owning graph. PinPaths are unique. In comparison to the EdGraph Pin the URigVMPin supports the concept of 'SubPins', so child / parent relationships between pins. A FVector Pin for example might have its X, Y and Z components as SubPins. Array Pins will have its elements as SubPins, and so on. A URigVMPin is owned solely by a URigVMNode.
