This is an IModularFeature, and so clients can query/enumerate the available ApproximateActors implementations based on the ::GetModularFeatureName(). However, the preferred way is to use code like the following: IGeometryProcessingInterfacesModule& GeomProcInterfaces = FModuleManager::Get().LoadModuleChecked("GeometryProcessingInterfaces"); IGeometryProcessing_ApproximateActors* ApproxActorsAPI = GeomProcInterfaces.GetApproximateActorsImplementation();
