Note:
Direct Light Filtering works only when you
use Shoot Direct Lights (page 3–69).Ifyou’re
notusingShootDirectLights,everythingis
considered indirect lighting.
For a 65% quality solution, increasin g the Indirect Light
Filtering value from 0 to 3 creates a smoother diffuse light. The
results are comparable to a much higher-quality solution.

Controls the creation of a radiosity mesh and its
size in world units.
In order to create the lighting of a scene, the
software calculates the intensity for discrete points
in the environment by subdividing the original
surfaces into elements which are p art of a radiosity
mesh. This rollout allows you to determine
whetheryouwantameshornot,andtospecify
the size of the mesh elements in world u nits. For
quicktests,youmightwanttoturnoffthemesh
globally. The scene will look flat, but the solution
will still give you a quick impression of the overall
brightness.
The finer the mesh resolution is, the more accurate
the lighting detail will be. But there is a trade-off
in time and memory.
