Hey =)
I´ve got a little problem. I tried to add a tattoo to my avatar in Unity. I just added it to the leg texture. The problem is that both legs using the same texture, that means that both got the tattoo now but I want it just at one leg… Can someone tell me how to get this to work? 
Good say.
You nees to create 2 diferent materials, eachmaterial with one texture, one with tatoo the other no. And apply each material to each leg.
Bye!
