Increasing the Shadow Integrity value creates more accurate shadow contour and
detail.
Shadow Quality Sets the total number of rays cast in the penumbra (soft area)
region, including the rays fired in the first pass.
These rays are projected from every point that is in the penumbra, or
antialiased edge of the shadow, to smooth it out.
The number of rays is as follows:
■ 2=5 rays
■ 3 to N = NxN
For example, setting Shadow Quality to 5 generates 25 rays.
The Shadow Quality value should always be greater than the Shadow Integrity
value. This is because the software overlays the secondary rays atop the first
pass's rays using the same algorithm.
Increase Shadow Quality to fix banding in the penumbra, and eliminate the
noise pattern from jittering.
