FACIAL ANATOMY FROM ZSKETCH BY TY SHELTON CH3

This post continued from previous post

At this point, the skull is really beginning to take shape. It should start to become very obvious as to which areas are coming together well and which areas still need a bit of work.

Once you are satisfied with the overall shape, go ahead and begin adding in a bit of detail. This should mainly consist of single ZSketch strokes that represent things like the teeth, the anterior nasal spine at the base of the nasal cavity, the mastoid process behind the ear cavity, etc.

As we near the completion of the ZSketch, make sure you fill in all of the remaining holes on the skull, including the

entire underside as well as the backside of the jaw bone.

Now, go back to the ZSketch sub palette and click the 'Optimize' button. This will clear out all of the ZSketch spheres that have been completely covered over by other ZSketch strokes and are no longer playing a role in the visible shape of the object.

Finally, turn on the button labeled 'PolyF', located just to the right hand side of your canvas.

You will notice that ZBrush has automatically created a «polygroup» for every one of the individual ZSketch strokes.

Though this can be extremely helpful in many situations, we can go ahead and just group them all together in one single polygroup for now. To do this, go to the tab labeled 'Polygroups', located in the 'Tool' palette. Click the tab once to expand the Polygroups sub palette and select 'Group Visible'.
