unreal.PCGPythonDataBridge

class unreal.PCGPythonDataBridge(outer: Object | None = None, name: Name | str = 'None')

Bases: Object

Lightweight UObject bridge for passing FPCGDataCollection (a USTRUCT) into Python scope. Created per-execution with a unique name so Python can locate it via unreal.find_object(). Used by the Python Data Processor node to give users direct access to input/output collections. todo_pcg:: This bridge exists because PythonScriptPlugin’s PyConversion headers are Private, so we can’t use PyConversion::NativizeProperty to transfer USTRUCTs directly between Python and C++. If those headers become public, this class can be removed in favor of direct struct marshalling.
