I don’t think you’ll be able to read it that way. You will need the actual C++ class definition.
However, there is a way to get at the data through C++ at runtime. Unfortunately, my understanding is that this piece has not been wrapped in V5 for C#.
Where uuidProvider is one of these:
// Custom render mesh providers.
RHRDK_SDK extern UUID uuidEdgeSofteningCRMProvider;
RHRDK_SDK extern UUID uuidDisplacementCRMProvider;
RHRDK_SDK extern UUID uuidCurvePipingCRMProvider;
RHRDK_SDK extern UUID uuidShutLiningCRMProvider;
RHRDK_SDK extern UUID uuidThickeningCRMProvider;
Does that help?
