A low error_bound needs a high count to prevent blotchness. Try to increase
error_bound, maybe as high as 1. This will also decrease the render time.
You can compensate by using a smaller low_error_factor to get more sampling
during the last pretrace step. Also, adding 1 or pretrace steps can help.
Increasing nearest_count up to 20 (the maximum) can also help by averaging more
value to get the final illumination.
