Cigarette Smoke

 
 
 

This compound lets you create a stream of smoldering smoke, like from a cigarette. Turbulence and wind are used to add realism to the smoke movement.

Plug its Execute output into a port on the ICETree node.

You can also choose Particles Create Particles Cigarette Smoke from the ICE toolbar and then pick an emitter object to create smoke using this compound.

Tasks: Particles/Presets

Output Ports: Execute

Emitter

Plug in the geometry from which you want to emit particles. This must be a geometry with a surface. You can plug multiple geometries into this emitter.

Rate

The number of particles that are emitted per second.

Size

Defines how large the particle is. This value is the particle radius, but the particle display size is the diameter. For example, if the Size value (radius) is 1, the diameter (display) size is 2.

See ICE Particle Size [ICE Particle Simulations] for more information.

Speed

Defines the speed at which new particles are moving when they are emitted, which is the number of Softimage units per second. If this value is set to 0, the particles are emitted, but simply remain on the emitting object.

See ICE Particle Speed [ICE Particle Simulations] for more information.

Color Gradient

Defines the particle color based on the colors in the gradient bar. The particle color is taken from this gradient at emission time.

  • You can set the color in each box below the gradient by selecting it and then using the color sliders.

  • You can add more boxes by clicking anywhere beneath the gradient, or remove boxes by selecting them and pressing Delete.

  • Set the position of each box by dragging it, or enter a value between 0 and 1 in the Pos text box below.

  • Drag the small circles above the gradient to set the range of each color defined in a box.

See Gradient for more information.

Wind Strength

The strength of the force applied to the particles or objects to get them to the target velocity. This value has turbulence applied to it.

Wind Direction

The direction of the force in XYZ global space. Note that the length of this vector is ignored, only the direction is considered.

Wind Speed

The target velocity for the particles or objects. If there are no other forces at work on a particle simulation except wind, particles will eventually reach the speed of the wind's velocity setting which, in some cases, can actually slow down the particle velocity at emission. This is because particles have an initial velocity of their own when they're emitted.

Turbulence Scale

The amount of turbulence applied to the parameter value.

Animation Speed

Changes the noise frequency of the turbulence over time. This value is the speed at which the noise evolves.
