human body textures?

I have a question, let’s say that I have made a low poly and high poly character for a game. The high poly character has fingernails while the low poly character doesn’t. Is there any way I can put the fingernails onto the low poly model via texture? I know how to do normal maps, but I don’t think that will solve my problem. HELP PLEASE!!!

P.S. Is this the right forum?

Would I bake textures, or Full Render?

Thanks for such quick responses, Richard. I will try to bake the textures and see if it produces the results I desire.
