Genesis 9 Skin detail converted to Genesis 8.1 Female.
Setup-
0.) Apply a PBR skin
1.) Add or replace existing detail textures
1.1) Remove any Detail weight maps (or not, personal preference)
2.) Remove Detail Roughness Specular Multiplier map, This one doesn't need it.
3.) Set Detail Horizontal and Vertical maps to 1 each, this isn't a tiled texture.
Enjoy.
