Left: Fog with noise
Right: Changing uniformity creates "blobby" fog
Uniformity Ranges from -1 to 1 and acts like a high-pass filter. The smaller
the value, the more transparent the volume is with discrete blobs of smoke.
Around -0.3 or so your image begins to look like specks of dust. Because the
fog becomes thinner as this parameter gets smaller, you'll probably need to
increase the density or the volume will start to disappear.
Levels Sets the number of times the noise is iteratively applied. Range=1 to
6, including fractional values. Enabled only for Fractal noise or Turbulence.
Size Determines the size of the tendrils of smoke or fog. Smaller values give
smaller tendrils.
