For details on using gradients, look up ‘Using gradients’ in the index.

On this page you can enable and

disable age effects and adjust

the animation properties of

various attributes.

With these settings, you can have puffs change their color, radius and luminosity
depending on how far away they are from the emitter. This is useful for effects where
the color, shape and luminosity changes over distance, such as the flames of rocket
boosters, for example.

Radius



For details on using gradients, look up ‘Using gradients’ in the index.

In the Age Radius gradient,

white creates the radius set on

the Shape page, while a black

or a dark color creates a zero or

small volume radius respectively.

So, on the left, particles start

small and grow evenly over their

lifetime while, on the right, the

particles are larger to start with,

shrink a little and then grow to

their full size.

The Radius gradient controls the puff’s radius over the particle’s lifetime; each

grayscale represents a radius value.

On the Shape page you can set the basic volume radius for the selected PyroCluster
material; without any other effects turned on, PyroCluster will use this radius to render
the cloud or smoke effects. However, if you enable Age Effects, it’s different.

A plain white color in the Age Radius gradient represents the radius defined on the
Shape page and a plain black color represents a radius of 0 (i.e. a dot). The left and

right edges of the Age Radius gradient correspond to the time of the particle’s birth
and death respectively.
