like this(bellow) in manual doesn't help at all We need video samples like phoenix fd has. Speed isze. Well how will we know what it is. Tweak and then cache and tweak and cache for hours. Give examples please
Perturb Speed group
Allows to control the parameters of turbulence in the velocity, giving the fractal noise to the speed. As a result, the wind speed at different points of space varies.
On
This checkbox enables this turbulence mode, and, accordingly, these parameters become available:
Speed Amount
Specifies the maximum speed deviation.
Size
Specifies the size of fractal noise.
Iterations
Controls the number of iterations (or octaves) used by the fractal function. Fewer iterations use less fractal energy and generate a smoother effect. An iteration of 1 is the same as turning Fractal off. Range=1 to 10. Default=1.
