if you want to use this approach to get a dense cloud cover there are
some drawbacks. You have to make sure that the containers of the cloud
do not overlap -> this will probably give some strange artefacts.

concerning your questions:
it would be quite tedious to modify the source code and tracing all the
dependencies throughout all the files.
Is there an example of a scene showing those black dots?
And which media settings do you use?
Are you aware, that the docs contain an error in the media section?

DEFAULTS

docs		correct
----		-------
intervals 10	intervals 1
samples 1,1	samples 10,10

I'm not really sure but I always thought intervals spwans a new trace
for each interval.

So try keeping the intervals low and instead raise the samples.
