Is this normal map or specular map issue? {Solved}

I tried frankenmeshing and successfully joined the mesh together and already tested run in game. Now, it's a recolouring and editing texture step (I followed the tutorials on this site about editing Bump map,shadow map and specular map.) but i have this unpleasant texture on sim's body. I don't know what cause this problem. So,i would ask for expert's clarification (i suspect specular map most since there's also unwanted blue tint on body,too)

Thank you in advance.
