yes, you need to manualy map them but it doesnt look as you expecting becouse you need to have normal maps and bump maps and you need to create themself.
Abad have you made the normal maps ? if you have, could you share them I'd like to try them and see what kind if a difference it makes. I'll give you 1000 points for sharing them 🙂
