reconstruct_blueprint_node
Repair Blueprint nodes after changing defaults or wiring wildcard pins. Forces UE to regenerate pins and propagate concrete types, then verify with graph readback and compile diagnostics.
Instructions
Force a Blueprint node to reconstruct after pin/default mutation.
Use this repair primitive after setting defaults or wiring wildcard nodes so UE can regenerate pins and propagate concrete types. Follow with graph readback and Blueprint compile diagnostics.
Args: blueprint_name: Asset name. node_id: Node GUID or short object name. graph_name: Graph containing the node. Default 'EventGraph'.
