Random Seed
The Random Seed control sets the starting number for the Rand() function. The rand(x, y)
function produces a random value between X and Y, producing a new value for every frame.
Aslong as the setting of this Random Seed slider remains the same, the values produced at
frame x are always the same. Adjust the Seed slider to a new value to get a different value for
that frame.
