I add Hd to my characters as this goes beyond normal maps and bump maps, bumps dont change the surface, and normal map add a nice skin/pores etc but hd can add more definition and wear to the skin, i tend to use all the tools in my basket, from bump, normal, displacement and Hd with a SubD set to 4. oh and to anyone reading this..... as i didn't know and it's hard to find any info, but you can use the HD morphs from characters in the Daz store on your own skins.

Getting old and still making "art" without soiling myself, now that's success.
