I was using a fairly high octaves number of 7 to do the mountains I had made
for the animation I'm currently playing in.
I was generalizing greatly the affect each parameter had:

#declare H = 0.25; // roughening<>smoothing
#declare Lacunarity = 4; // roughening<>smoothing
#declare Octaves = 7; // smoothing<>roughening (computationally intensive
higher)
#declare Offset = 0.5; // height (suggested to start as 1 in the Doc.)
#declare Gain= 2; // smoothing<>roughening (I used too much maybe)
