Q:  Why are some of them sticking out and others are sticking in?
A:  That's what I'd like to know.

This is a head mesh, not terribly well-modeled I admit, subdivided three 
times, with the normals of the original faces represented by cones 
pointing in the normal direction.  The normals for the final mesh are 
not smoothed.

As you can see, the normals are not consistent, in spite of a macro that 
is supposed to be making them consistent, and which I thought was fixed 
when I announced a bug fix early this AM.

The lighting, by the way, is a bunch of jittered area lights.  I've been 
testing out ideas.

Debugging in progress...

Regards,
John
