You need to use the turb_depth omega lambda and octaves to adjust the
various clumpiness of fog;
octaves will determine how many times to go into the turbulence using lambda
and omega to determine how chaotic or quiescent to make it.  The turbulence
is the overall amount to apply using these.  Lower numbers meaning less,
higher more.
I might have an example to show if I can find it.
