Particle systems

Particle systems are avaiable in the compositing editor, both in 2D and 3D compositions. Some particles configurations work better in 2D, other in 3D.

Adding a particle system

You can add a particle system with the default settings, or use one of the presets as a starting point. There are also several demos to help you find out how to use particle systems.

Emitter settings

• spread
  how much particles will follow the initial trajectory

• gravity
  replicate the gravity

• static
  don't animate the particles, but instead choose a time to take a 'snapshot' of the particles

• emission duration
  for how long the emitter with emit particles (in seconds)

• emitter strength
  the power of the emitter

• free floating
  enable it to add a smooth free floating movement to the particles, like fireflies

• lock rotation
  keep all particles facing the camera, ignoring their rotation

• re seed button
  click it to generate a new random sequence, usefull when duplicating a particle system to avoid the copy to be exactly the same as the original

Particles settings

• particles type
  choose one of the avaiable shape, or select an image from the files library

• animate color over life
  rather than a unique color, the color of particles will change over time

• stretch
  stretch the shape of the particles based on their velocity

• * over life
  click on the gray bar to set values, the pink bar represents the value over time
