The Help for VIZ 2008 says this about parameters for advanced ray-trace shadows:

“Antialias 1-Pass—Casts a bundle of rays. The same number of rays is cast from each illuminated surface. The number of rays is set using the Pass 1 Quality spinner.

Antialias 2-Pass—Casts two bundles of rays. The first batch of rays determines if the point in question is fully illuminated, shadowed, or in the penumbra (soft area) of the shadow. If the point is in the penumbra, a secondary batch of rays is cast to further refine the edge. The number of initial rays is specified using the Pass 1 Quality spinner. The number of secondary rays is specified using the Pass 2 Quality spinner.”

I can’t find these Pass Quality spinners.  I’m wondering if in the time between the writing of the Help and the publication of VIZ 2008, the spinners got renamed as Shadow Integrity (Pass 1 Quality), and Shadow Quality (Pass 2 Quality).  Is that the case, or are these spinners found elsewhere?

I would assume you are correct in your assumptions.  It is not unheard of for the Help file to be slightly off from what is reality, especially when it comes to Viz.
