I finally got the texturing and bump mapping, long with subsurface scattering, to a satisfactory outcome with Piero's legs and feet. This presented a tremendous challenge (since the series was done in 2.66 and I'm using 2.78b). But with perseverance and determination I made it, and the reward was worth the struggle. Thanks Kent for your great mentoring and encouragement. I don't know if Piero would be laid to rest jut yet, my friend. It IS possible!
