Particle Flow

 
 
 

Particle Flow is a versatile, powerful particle system for 3ds Max. It employs an event-driven model, using a special dialog called Particle View. In Particle View, you combine individual operators that describe particle properties such as shape, speed, direction, and rotation over a period of time into groups called events. Each operator provides a set of parameters, many of which you can animate to change particle behavior during the event. As the event transpires, Particle Flow continually evaluates each operator in the list and updates the particle system accordingly.

To achieve more substantial changes in particle properties and behavior, you can create a flow. The flow sends particles from event to event using tests, which let you wire events together in series. A test can check, for example, whether a particle has passed a certain age, how fast it's moving, or whether it has collided with a deflector. Particles that pass the test move on to the next event, while those that don't meet the test criteria remain in the current event, possibly to undergo other tests.

NoteOperators and tests are known collectively as actions.
  • How Particle Flow Works

    Particle View is the primary interface for building and modifying Particle Flow systems. The first event in the system is always a global event, whose contents affect all particles in the system. It has the same name as the Particle Flow source icon.

  • Particle Flow User Interface

    This section describes the various interface elements in Particle Flow.

  • Actions

    The Particle Flow components for creating particle systems are known collectively as actions. These are subdivided into three main categories: Operators, Flows, and Tests.

  • Simulation and Advanced Data Manipulation

    The Simulation and Advanced Data Manipulation tools for Particle Flow are included with the Extension for Autodesk 3ds Max 2013. Most features described in this section are currently available only to customers on active subscription for the Autodesk ® 3ds Max ® Entertainment Creation Suite Premium or Standard, or the Autodesk ® Entertainment Creation Suite Ultimate; the Cache Disk and Cache Selective feature sets are available to all 3ds Max customers on active subscription.
