Initial Meshing Size When improving the face shape, faces that are smaller
than the Initial Meshing Size are not subdivided. The threshold for deciding
whether a face is poorly shaped also gets larger as the face size is closer to the
Initial Mesh Size. Default=12 inches (1 foot) for US Standard units and 30.5cm
for metric units.

Shoot Direct Lights When adaptive subdivision or shoot direct lights is on,
the direct lighting on all of the objects in the scene is calculated analytically,
based on the following switches. Lighting is analytically computed without
modifying the object's mesh which produces lighting that is less noisy and
more pleasing to the eye. This switch is implicitly enabled when using adaptive
subdivision since it is a requirement. Default=on.
This switch is available when the Use Adaptive Subdivision switch is turned
off.
Adaptive Subdivision with light settings turned off
NOTE Lighting from lights that are not included while shooting direct light are
calculated using random sampling. These lights also are not able to affect the
adaptive subdivision of objects.
