Hello all. 
I am new to working with V4.  With V3, there were mats in the !MAT V3 MapsHC that could be used to change the V3 texture from very light skinned person to an african american.  I can not find anything like that in the V4 MATerials Standard-Res folder.  Is there a way to change V4's skin tone without having to buy new textures?
Thanks for any help.
