Meander

While Flocking controls how particles interact with each other, Meander controls the independent wandering of each particle. Meander is affected by the Mass of the particle. It can be used to add some nice individual movement, or in tandem with other features such as Attract and Separate in Flocking to add some group motion around it.

Turn on Enable Meander to activate the Meander Simulation.

In the following examples we are using a Box Emitter with Y and Z set to zero, some size randomness added, and the Mass affected by Size turned up to 100%

Affect Direction

allows the individuals to wander, like a crowd milling about in a mall:

Affect Speed

adds variance to the speed of individuals, like traffic moving in different lanes:

Here’s the Affect Direction with some Attract turned up in Flocking. Since Mass is taken into account, the smaller ones are getting drawn to each other quickly:

Meander Controls

adjust the underlying guiding fractal.

• M Scale : sets the overall scale of the fractal.
• M Complexity : the number of Perlin noise fields added together to form the fractal.
• M Octave Multiplier : sets the influence of each added noise field as compared to the previous field.
• M Octave Scale : sets the scale of each added noise field compared to the previous.
• M Evolution Speed : sets how fast the Turbulence Field evolves over time.
• M Evolution Offset : offsets the Turbulence Field in time. Evolution Offset gives more control over how the Turbulence Field can be moved.
