But i’ve been searching through the forums and i cant see nothing similar to this, let me explain: I’m new to zbrush, so i took the provided head as base for some testing and practices. The moment i wanted to add some polypainted texture, i added UVs from MAX, resulting on this as the baked texture… 
Trying to make displacement of hd detail gives similar (faceted) results… being the “smooth UV” button pressed, any ideas on how to avoid the faceted colors please?
Ah!, im using zbrush 3.5R3
