Karen 7 textures

bevdog896_d08d9c913a

Oooh Kay. So I've notice that when I apply genesis 3 genitalia to a Karen 7 character and then apply the texture mat from the Karen 7 material list, when I come to render the genital area comes out a reddish colour. Any ideas? 

 

Ps, apolgies for the nature of the question, just can't figure out whats going on :)
