4 Play back your simulation.
The particle smoke is still not rising as expected because now it is not
forced up enough by the Nucleus Gravity. Maya Nucleus solver applies
Gravity to objects as if the objects were scaled in meters, regardless of the
units in which your scene was created. Therefore, to maintain a real world
force of gravity acting on the objects in your simulation, you may need
to adjust the Nucleus node Space Scale. Decreasing Space Scale results in
a visibly increased gravitational affect on the nParticles and makes them
rise properly.
5 In the Attribute Editor, click the nucleus1 tab.
6 In the Scale Attributes section, set Space Scale to 0.05.
7 Play the simulation.
The nParticles now rise through the field and behaving more like smoke.
In the next section, you use the nParticle Shading attributes to make the
nParticle object look more like cigarette smoke.
Adjusting nParticle Shading attributes
By adjusting nParticle Opacity, you can mimic the way smoke disappears into
the air as the nParticles age. You can then set the Color ramp to add shades
of white, gray, and blue to the smoke.
