I’m trying to get triangles from my mesh like this:

void UMyFunctionLibrary::InvestigateTris(UStaticMesh* Mesh, FVector Point, FTransform Transform, UObject* Outer)
{
	auto SMDesc = Mesh->CreateStaticMeshDescription(Outer);
	UE_LOG(LogTemp,Warning,TEXT("%d"), SMDesc->Triangles().Num())
	auto Desc = Mesh->CreateMeshDescription(0);
	UE_LOG(LogTemp,Warning,TEXT("%d"), Desc->Triangles().Num())
}

I’m getting the mesh from editor like this

But both logs say that there are 0 triangles in my static mesh this is the same if I pass null as Outer and the function auto generates the outer by package
