■ ZBrush and Working with Imported Meshes 85Figure 3.9 The stretched faces subdivide less efficiently.
Problems with stretched faces can sometimes be
corrected or at least reduced. Under the Tool → Subtool
menu you will find the Reproject Higher Subdiv level
button. This button is used to correct areas of stretched
faces. If you find a problem area like a nose or ear
where the underlying geometry is stretching to its limit,
step down a subdivision level, smooth the mesh enough
to even out the edge distribution, and then click the
Reproject Higher Subdiv button. This will reproject the
higher-res details on top of the newly smoothed edges.
Often this can reduce problems in areas of stretched
geomet r y.
There is another slider that you will find useful
in problem areas like the ones we’ve been discussing.
Under the Tool → Deformation menu you will find a
Relax slider. This slider can help correct stretched or
otherwise jumbled edges that sometimes result from
stretching the geometry too far.
Figure 3.10 Details here are less sharp because of the
lower subdivision level in the longer areas.
