Defines the number of octaves to be added to the turbulence. The value of the turbulence is calculated such that for each
octave a noise of half the amplitude and twice the frequency is added. A complexity of one is simple noise with no fractal
pattern.
Complexity has an impact on performance. A turbulence with 2 octaves takes twice as long to calculate than a turbulence with
only 1 octave.
