Mellow,
I'm not sure to understand what is your question, but I'm going to try an answer

- If you want to change the different body part of your character, Unity allows you to paste a texture into another one using scripts. Don't ask me how ... I'm just an artist

- In the previous version of the Warriors and Commoners, characters used 5 different materials (head, body, hans, legs and feet). The $150 version of the pack available in the
www.frogames.net Store includes both the 1 material and the 5 materials version. Contact me if you want to update to it ( christophe (a) frogames.com )
