PYROCLUSTER
Here is an example of using the color mix feature. First, let’s assume that you have
dened a gradient for Color on the Globals page, as shown below. So each puff
consists of a yellow core, turning through red to blue at its edge.
The gradient
controls the
base color of the
particle cloud.
You’ve then created a gradient for Color on the Age page that looks like the gradient
in the second picture below: red at the particle’s birth, turning green as the particle
dies.
The following results would be rendered for a Color Mix gradient that started at
white, turned gray in the middle and ended at black. Red is mixed in at birth, turning
the whole particle red. As the particle ages, dark yellow is mixed in, allowing the
yellow core to show through. Then darker colors predominate as the particle dies.
The particle is also becoming more transparent as it dies out because of the Alpha
set on the Age page.
The Color gradient on the
Globals page, set up to give
each particle a yellow core,
spreading out to red and then
blue at its edges; the gradient
has three knots (yellow, red,
blue from left to right). No Age
effect has yet been added.
