Sorry to be such a bother, but I tried to enter the settings you suggested
and I keep getting errors....this is how I entered it:
global_settings {radiosity {count 200, error_bound 1}{ max_trace_level 100
ambient_light rgb<0.830000, 0.830000, 0.830000> assumed_gamma 1.0}
// sunlight
light_source { < 4226.182699, 14281.480312, 9063.078165 >, rgb <1.000000,
1.000000, 1.000000>
parallel point_at < -0.422618, -1.428148, -0.906308 > fade_power 0}
}
The radiosity line keeps getting errored....what am I doing wrong?
