I modified it a little bit to fit the runtime conversion.

void URuntimeToolBPLibrary::DynamicToStaticMesh(const UDynamicMesh* DynamicMesh, const FName Name, UStaticMesh*& StaticMesh)
{
	if (DynamicMesh == nullptr)
		return;

	const UWorld* World = DynamicMesh->GetWorld();
	UStaticMesh* LocalStaticMesh = NewObject<UStaticMesh>(World->GetCurrentLevel(), Name, RF_Transient);

	LocalStaticMesh->bAllowCPUAccess = true;
	LocalStaticMesh->bSupportGpuUniformlyDistributedSampling = true;

	LocalStaticMesh->SetLightingGuid();

	FMeshDescription MeshDescription;
	FStaticMeshAttributes StaticMeshAttributes(MeshDescription);
	StaticMeshAttributes.Register();

	const FDynamicMesh3* Mesh = DynamicMesh->GetMeshPtr();

	FDynamicMeshToMeshDescription Converter;
	Converter.Convert(Mesh, MeshDescription);

	TArray<const FMeshDescription*> MeshDescriptionPtrs;
	MeshDescriptionPtrs.Emplace(&MeshDescription);

	UStaticMesh::FBuildMeshDescriptionsParams mdParams;
	//mdParams.bBuildSimpleCollision = true;
	mdParams.bFastBuild = true;
	mdParams.bAllowCpuAccess = true;
	mdParams.bCommitMeshDescription = true;

	LocalStaticMesh->BuildFromMeshDescriptions(MeshDescriptionPtrs, mdParams);

	FStaticMeshRenderData* LocalStaticMeshRenderData = LocalStaticMesh->GetRenderData();
	FStaticMeshLODResources* LocalStaticMeshLODResources = const_cast<FStaticMeshLODResources *>(LocalStaticMeshRenderData->GetCurrentFirstLOD(0));
	if (LocalStaticMeshLODResources && LocalStaticMeshLODResources->Sections.Num() > 0)
	{
		for (int i = 0; LocalStaticMeshLODResources->Sections.Num() > i; i++)
		{
			LocalStaticMeshLODResources->Sections[i].MaterialIndex = 0;
		}
	}

	StaticMesh = LocalStaticMesh;
}
