check thread below about realistic faces to see the purpose of this, not a great example its a quickie just to illustrate a point... the head is a roughin for another project im working on {its about half way there} i added a scaled down pic of the quickly done texmap at the bottom ... as you can see just adding a texmap nomater how detailed it is to a figure doesnt make the figure look like the person the topography of the mesh needs to be reasonably close
Y'all have a great day.
