The FireFly™ particle system allows creating elaborate real-time particle effects in a true interactive 3D compositing space. There are 3D and 2D particle systems are available on Pandoras Box.

Since version 8, Particles are rendered based on the blend mode of the Layer. In prior versions, they were mixed with the background as if their blend mode was "Add". With the ability to choose a distinct blend mode, you can now also use particles darker than the background or create other effects.

Particle System Layer

The easiest way using particles, is to add a "Particle System Layer". Simply right-click a Site and choose "Add Devices". This layer is optimized and offers only parameters mostly needed for particles.

Old Workflow: Adding Particles to a Video Layer

particles_tabThe older workflow is still supported but requests more steps and has no advantages. In order to use the Firefly Particles you have to add a Particle System to a Video Layer first. As a second step you may then drag one or several emitters onto the specific system.

First, open the Particles tab: Open the Tabs menu and click on "FireFly Particles". Open the "Systems" folder and drag a 2D or 3D Particle System onto a Video layer in the Device Tree. Alternatively, select the Layer to see its parameters in the Devices Controls tab and drag the Particle System on the empty space right next to the last parameter.

With the particle system you define the environment, setting up the opacity of the system, Gravity and Wind. To see how these settings affect the emitters, you have to add at least one emitter.

Next, open the "Emitters" folder and drag a 2D or 3D Particle Emitter onto the Particle System (not the layer), either in the Device Controls tab or in the Device Tree on the entry "Particle System" under "PS".

The particle system section is now enhanced by the emitter parameters.

Drag

Drag of particles; as drag is a force which decreases the velocity / speed of an object it resists the particle´s motion, thus it increases the influence of gravity and wind

Particle Examples

In the following examples these files are used:

In the examples only the parameter values different from the default values are mentioned.

Example 1:
_img108
Image above: Here the emitter type is set to "Point", there is no gravity set for the particle system.

_img109
Image above: The particle systems gravity is now set to 155 – the emitters will fall down after they flew into positive Y direction.
_img110
Images above: The emitter type is changed to "Line", with the Radius set to 12. No gravity.
Left) Viewed from the front, Right) viewed from the side.
_img111
Images above: The emitter type is changed to "Circle", with the Radius set to 12. No gravity.
Left) Viewed from the front, Right) viewed from downside.
