Creates the smoke effect.

Sets the options when
creating a smoke effect. Here are the options:
- Sprite Image Name
-
Identifies the
filename (with extension) of the first image of the series to be
used for the smoke. To use the default images supplied with Maya,
enter the name Smoke.0.
To use files from a directory
other than the sourceimages directory in your current project, specify
the complete path.
The images must have
filenames in the format name.1, name.2, name.3,
and so on.
To choose a different
filename after you use the Smoke effect, display textures in the Hypershade and double-click
the file1 texture to display the Attribute Editor.
The Attribute Editor has an attribute
named Image Name that specifies the filename and path.
- Smoke Particle Name
-
Names the emitted particle object. If
you do not provide a name, Maya gives a default name to the object.
- Cycle Images (Cycle Enabled)
-
If you
turn on Cycle Images, each emitted
particle cycles through the series of images over the course of
its lifetime. If you turn off Cycle Images,
each particle picks one image and uses that throughout. You can
turn this attribute on or off in the emitted particle shape node.
- Start and End Image
-
Specifies the
numerical file extension of the starting and ending image of the
series. The extension numbers in the series must be continuous.
- Smoke Sprite Min and Max Lifespan
-
The particles
live a random time uniformly distributed between the Smoke Sprite
Min and Max Lifespan values. For example,
if Min Lifespan is 3 and Max Lifespan is 7, each particle lives
from 3 to 7 seconds. To change the height of the smoke without affecting
speed, adjust these attributes.
- Smoke Threshold
-
When each particle is emitted, it has an opacity
of 0. The opacity gradually increases, hits a peak, then tapers
off to 0 again. The Smoke Threshold sets the moment
the opacity hits its peak, specified as a fraction of the particle’s
lifespan. For example, if Smoke Threshold is 0.25,
each particle’s opacity peaks at one-quarter of its lifetime.
- Smoke Opacity
-
Scales the entire smoke opacity from 0 to 1.
The closer to 0, the lighter the smoke. The closer to 1, the denser
the smoke. The expression created by the Smoke effect controls opacity
on a per particle basis; it uses the value of this attribute.
