Hi

Could someone please explain, how pretrace_start affects the quality of the
final image? Radiosity pretrace phase is mentioned quite shortly in
documentation and tutorials, and only pretrace_end gets explained. As far
as I understand, the difference between pretrace_start and pretrace_end
specifies the number of pretrace steps. E.g if I specify pretrace_start
0.08 and pretrace_end 0.01 there will be 4 steps. But will there be any
difference if I e.g. specify pretrace_start the same as pretrace_end, and
there will be only one step?
