Random effector

The random effector is very straight-forward as it simply adds randomness to any matrix of objects. You can randomize the position, scale, or rotation of the elements using a random function or several noise functions. The gaussian noise mode is more wave-like than random. The randomness can be contrained to a specific axis. The area effected can be controlled by falloff types, falloff size and strength. Animating the random effector's falloff can produce some interesting special effects, something close to an explosion. The Random effector can also make the clones have random colours by enabling effector colour on the parameter tab. Like other effectors the random effector can be used to define weightings on the clones or matrix objects / particles. Reducing the strength of the random effector to 0 removes the effect completely. This can be used for to do cool animations where objects are spread far and wide and then over time, they assemble themselves on to objects just as in the MoGraph tutorial 4 animation shown later in the review.

We've used the Random effector in a number of places throughout the review. Here's an example where both the red and blues cubes are being transformed with a Shader effector. The cloner object for the blue cubes has a random effector.

At the Cafe we've got a 8 minute 22 second tutorial on producing a similar animation. 10mb Flash format video.
