# Line 39 | Line 39 | for specific machines and users:
39                  Values greater than 20 use over 4 Kbytes per
40                  light source, which can add up to a lot of
41                  memory in scenes with many sources.

43 + -DAVGREFL=R     Set the average surface reflectance for the purpose
44 +                of indirect irradiance calculations to R, where
45 +                R is a real number in the range (0,1.0).  The
46 +                default value is 0.50 (50%).  This value indirectly
47 +                controls the maximum number of ambient bounces,
48 +                which can never be more than the log of the -ad
49 +                setting times the log of AVGREFL.
